imagine that there exists people like this that gives you an honest respectable in depth video of something that you can actually learn from, i have a hard time learning things but i only had to watch this once
Very cool cars! I had several Datsun Z cars growing up. I always wanted to turbo them, but never had the time or money back then. Now Im working on a blow through system for my Studebaker 289 V8.. Stude was the pioneer of boost.
Thank you so much, seems when people start talking forced induction they throw a bunch of side-remarks in there and complicated everything they're saying to show off their words. From a guy with no turbo experience whatsoever, I appreciated this video very much and it pointed me in the direction I was looking for.
Although I drive an 86 z28, I still love watching informative stuff on cars, such as boosting. Awesome video, I'm not a forced induction expert, but I learned alot.
Bryan Dunn Lots of potential in the Camaro series. Lots of budget twin turbo kits available for the Small block Chevy engines. Superchargers are great in the Camaro as well.
Budget Boosting Agreed, I can pickup the piping, fmic, wastegate and bov, and a decent (non-ebay) turbo for a little over a grand. My problem would be tuning, my car uses the TPI setup from gm, so its run off of an ecm with a pretuned memcal. I think my next project is going to be a mkiii supra, although I haven't decided whether or not I like the 7m-gte platform more than the 1jz.
DUDE...I had a 77 280z and would have gave my left nut to have that set up. This was the best most simple, straight forward DIY how to on a budget even. Never know you could turbo a carbed motor. And compared to an EFI upgrade + turbo's it's a real budget build with big power potential. While retaining drivability.
starbattles1 Yes, I remember when I decided to go that route due to the stock fuel injection not handling the turbo set up very well. I went the blow through turbo route and I have liked that set up the best. I started with the Demon 650 blow through carb which was pretty good and eventually to the Quick fuel SS-650-BAN 4 barrel carburetor and I like it even more. I have the intake and exhaust manifolds off this Z car waiting for a custom twin turbo header which a friend of mine fabricated to fit two of my z cars which will fit any z from 1970-1983, all the L series inline sixes. It was fabricated to fit in these cars once the air conditioning compressor is removed and a few other things that are in the way for the twin turbo setup. To me no A/C is a small price to pay for a twin T04e powered L28 Z car. Once I get this new twin turbo header, I will get with my fabricator and he will start making them so we can sell them to others desiring twin turbo z cars. We will sell them on our budgetboosting ebay account where we currently sell our window stickers.
All Out Throttle awesome, boosted Mustangs fun to run. They are very popular at NMCA races in all classes. Would like to race that series in the future.
I have been referring to this video for years, thinking about various vehicles I've had over the years that had carbs on them. But I'm doing it finally. Putting a turbo on an old 85 dodge ramcharger with the 318. I'm hoping to get it done before a big trip to moab Utah next April
@@ChinzySpecials uhh......😅 not so good. The weather got bad so I had to stop working on it for like 2 months. We got thw motor and trans in, and got the motor fired up for thw first time without the turbos, and then went to move it undernits own power for the first time, but something is wrong with the trans, so it has to come back out
@@garymaddux2000 haha I get that completely I'm doing a single turbo on a sbc. Got the turbo next is blow through carb and all the rest of the parts. Turbo kit will be made of pure exhaust tubing haha
@@ChinzySpecials I still need to get my turbo and blow through carb. Or I might go with an efi setup to make it simpler. For now, my headers just come up and point forward at where the radiator use to be lol.
@@garymaddux2000 haha I still have to gap the rings haha got the turbo engine all apart in my shop haha. The truck is under a snowbank lol. But I'm just throwing pretty much using every paycheck for parts haha. Easy to do when you are 18 lol. But let's of projects as it it
Austin Hermann Outstanding, do make sure you have the great assortment of gages to monitor all the engine perimeters that will change when adding boost to an already strong engine.
Thanks a lot a light bulb went off in my head when you mentioned the T connection for the oil supply. I just realized that engine oil is under pressure from the oil pump so all you have to do is tap into that pressurized oil and it will be pushed into the turbo... I used to be confused as to how turbos got fed with oil O thought maybe the turbo has a pump inside that pulls oil from the oil pan or there's gravity feeding but none of those sound like they would work.
Huh, I have a 280zx with an L28 EFI. I thought that you HAD to go Megasquirt, big injectors, T3 and whatnot. But this looks very interesting.... I’ve never seen a carbureted car that is also turbocharged. Thank you for introducing this route to me. I’m considering this now that I see it.
The carburetor is designed for boost blow thru. It is a quick fuel 650-BAN www.summitracing.com/parts/QFT-Q650-BAN. This carburetor with an arizona Z 4 bbl intake manifold will allow boost thru carb without complicated fuel injection systems. arizonazcar.com/engine
Blowoff* valves aren't necessary, but bypass valves in general, yes, ALWAYS run one on a boosted gasoline setup. Important tip: a blowoff valve is a specific type of bypass valve. I know stock tuning sometimes won't compensate quite correctly for a true blowoff valve [versus a stock bypass valve], but running a full on blowoff valve is undeniably safer than having no bypass at all. When the throttle plate closes under boost, if there's no bypass valve, that pressurized air has nowhere to go but back out through the turbocharger, in the wrong direction. Even if it doesn't literally cause the turbo to momentarily spin backwards, it can still mechanically stress the turbo unnecessarily. Overall good video though. Always run some sort of bypass valve on your turbocharged gasoline engine.
Your in with this here,and thanks for a brief explanation of how the thing works I've studied little about the systems but always held interest in the older cars run with much electronic assist.
arthur clark Yes the older cars really benefit from turbocharging. I see many old monstrous twin turbo Camaros, Corvettes, Mustangs and many others blow through the traps and very high speeds and very low times at Top Gun Raceway.
back pressure is not considered from the point of bottom dead center but again the boast adds pressure the cylinder should test positive for vacuum if valve timing is correct likely in most of the older cars it's not as tight or correctly timed when it is the turbo is likely larger than normal
arthur clark At idle a turbo engine will see its normal vacuum, as load is added to the engine and boost increases, vacuum will become positive pressure so having the stock vacuum advance will not benefit the older vehicles. I removed the vacuum from my electronic distributor so it is a constant and no adjustment on vacuum. I also install a boost referenced fuel pressure regulator that ensures fuel pressure rises as boost rises. When much larger turbochargers are installed, usable boost will take longer to build up and directly reflect negative vacuum and boost pressures. One way valves or breathers should be installed to ensure boost does not pressurize the valve covers or engine block. Lots of things to consider when turbocharging a non-turbo car. Its quite the adventure though.
Terry Lewis Nice, lots of aftermarket support for fox body mustangs and many have been successfully turbocharged to very monstrous proportions. I really like the foxbody and its potential. Thank you for watching. I made 4 new videos and two of them are related to turbo conversions.
I’m building a 91 Isuzu 2.3 turbo. Trying to find a decent manifold that’s not 700.00. Geminiturbo had a nice manifold and other than stock all I can find. Thanks for the info. Hopefully by mid summer I’ll be boosted!
You could have an adapter flange made with a T3 turbo flange and a custom made bolt on adapter for your intake manifold to run a holley style blow through carb.
Sorry I'm late to the party, but you can use a standard carb in two ways. Firstly isn't so easy (unless it's fairly commonly done with that model of carb for example SU carbs), seal up any vents/throttle shafts etc and find a way of venting the float bowl as well as being able to pressurise it on boost. *Second & much easier* but less tidy maybe is if you build the whole carb into a plenum chamber. This means the whole carb inside and out sees boost and thus no excess pressure is put on it. You then only need to seal up the point the throttle cable and fuel line enter, just make sure to use a linear fuel pressure regulator with the plenum set up so that your fuel pressure stays at the correct level relative to the boost rather than the boost overcoming the fuel pressure causing the car to lean out.
How the hell are you going to say building a boost box for a carb is easier than $50 worth of mods that anyone can do in a day to any Holley carb easier ? To the original poster if you haven't already bought a blow through there's a right up by hanger18. Not everything listed is necessary unless your making 18psi plus. I have built 3 Holley blow through carbs for around $50 each. But the most mine have seen is 15psi.
I thought I had a Z problem lol. keep it up, good to see another blowthrough z running around. my blowthrough setup is using triple side drafts, but this is what i was planing to do had i not found all the parts. great video!
Budget Boosting I believe I found your website with the old HKS triple deuce blow through turbo kit. I have always liked that kit ever since I saw it in Japan on an S130z with twin TD06 turbochargers on a 3.1 stroker. That car was wicked and that kit is severely hard to find. In the states Jim Cook Racing used to sell the Cartech triple weber side draft complete kit including a T04 turbocharger, external wastegates, intercooler and all the tubing and bolt ups necessary for installation for around $3500. If only those complete kits were still for sale, that company would make a fortune since there are many old Z enthusiests than there were then..... I like the HKS set up you installed, since you were running rich, a much larger turbocharger would fix that, somewhere around a T70 with ball bearing, 15-20 lbs of boost, 100 octane fuel and you would be golden.
Nice job on the blow thru setup!! I had a 79 280zx I converted to turbo but kept the EFI and it was a pain to get enough fuel to the engine at higher boost levels so I ended up using hobbs switches and extra injectors to feed it enough. Detonation was always a problem until I replaced the distributer and ecu with ones from a turbo car, then I used water injection at higher boost levels to prevent detonation. Now I got an 86 4x4 Nissan pickup with a 2.4 liter 4 banger and I'm planning a blow thru setup using a t3/t4 hybred turbo and intercooler fed into a Holley 350 2 barrel that's been prepped internally for turbo use with a boost referenced power valve and pitot tube on the bowl vent to keep a positive pressure in the bowl along with an EFI fuel pump and aeromotive boost sensing regulator. I have all the parts gathered up and ready now but need to get a smaller power brake booster since the turbo won't fit in there with the stock booster.
SuperDaveZilla I also first tried the fuel injection on my 79 and the fuel delivery had issues and that is what led to my using the blow through setup. I even ran the MAF sensor in the boost path just prior to the intake manifold so the MAF directly adjusted to boost but even that was not enough fuel delivery for boost and the low octane pump gas. Found that the blow through set up works well and will even work with the pump gas as long as the boost is not too high. Thank you for watching and look forward to some pictures of the Nissan 4x4 truck blow through when its done.
I forgot where your other video regarding the fuel pressure regulator, but i'm going to post this here. In your fuel pressure regulator video you said you had one for boost, yet they also make one for vacuum. So, in my vehicle which runs a carb but not any boost, would it be practical to put a vacuum controlled fuel pressure regulator to keep my carburetor with fuel?
Do you need an intercooler? I read some suggesting it will run better without since the fuel will mix better with air at higher temp and the boost isn't high enough that temp will be a problem.
Mmm perfect for my project I have 1987 mazda b2000 truck but is a carburetor I never thought u can boosted time to work on it if I have any questions hope you can give me some ideas or information thanks
Like the idea... how much boost do run? I own 71 240z with l28et on megasquirt... the cost of your Demon carburetor was about the cost of megasquirt standalone.
There is spring in blow off valve what you can usually adjust tighter and it isn't open with low boost if is it adjust hard. you can hear tsuhhh sound when it's open and there isn't thad sound.
What if the turbo used for 110cc carburetor bike? how the placement like? Is it from turbo to carburetor and then to the engine, or from carburetor to turbo then to the engine?
Very informative. I am considering building one. Currently,I have a 496ci BBC that is highly modified. I run a Dominator 1050. It has annulars. I can't use it with turbos,... right? Do you recommend air to air or a water to air intercooler?
Couple questions. WHat boost is the carb capable of handling? As much as large jets allow? How much boost have you got it to so far? I will be doing this on a 351 Cleveland. Any thoughts or suggestions?
starbattles1 I was running around 18 pounds of boost. It should support 21 pounds just fine and jetting and other factors such as fuel octane and timing also will help increase or limit boost ranges. I am considering turbocharging my 1989 F250 4x4 with the 351 Winsor V-8 in the future when my other cars get done....
hi Matt, so where is the best place to put an external wastegage on a turbo setup is it between the exhaust manifold flange and turbocharger.also what exhaust manifold you used for your setup.did you use a datsun 280zx turbo manifold?
f rod best place for ext wastegate is at the end of the exh manifold just before turbo flange or between exhaust manifold and turbo flange. I used a Nissan 280 zx turbo exhaust manifold I found on ebay. Some turbochargers have provisions on the exhaust housing for external waste gates. I have seen them as options on turbonetics turbochargers.
oh ok I see.I saw a wastegate adapter in ebay.I wanted to know if I can use that adapter to mount a wastegate without having to cut and weld tubing to add a wastegate.Let me know if you think that will work. www.ebay.com/itm/Progate-T4-Wastegate-Adapter-/171391515044?pt=Motors_Car_Truck_Parts_Accessories&hash=item27e7baf9a4&vxp=mtr
f rod that adapter looks good. Its a t3 to t4 with external waste gate hook up. Just need a t4 turbo like a gt45, t04b or any turbocharger with the t4 flange to fit the adapter.
All those Datsuns .. I have a couple . My brother has one with 350 , lowered ,nitrous , flares , anyway thanks for showing the turbo , I want to put one on my c10
Hey man, nice video. Going to do a blow through carb lt1 and had some questions. If you remember.... how much boost were you running ? Did you ever need to get a brpv ? Thanks.
would you have to advance your ignition as well? would you not only have to change the idle ignition timing but also how fast it changes and the WOT ignition timing? how would you know how much to do it? and how would you go about it? by modifying the distributor? i have a bmw m10b18 not whatever this car is by the way
Budget Boosting what are these devices called? the ones to control timing, are they sort of like an FMU but for timing? my main problem at the moment is i live in europe and the only blow through carbs i can find are from america, expensive and then i have to have them shipped on top and maybe pay tax, and as they dont even sell them here i cant see it being easy to find one second hand. i might have to give up on this which is a shame as a boosted, carbed 4 cylinder would be fairly rare thing to see, and really cheap to buy replacement engines for and such. might just have to engine swap to something with fuel injection and do that :( sounds so boring compared to boosting a m10, would be like my own version of a 2002 xD other option is to try megasquirt the carbed engine, but for that money i could just buy a fuel injected one. i suppose i gotta choose easy, cheap and boring. or hard, expensive and epic xD
+Charlie Ward would be real neat if you could find a used 335i engine, they are well over 300 hp 300 lb torque twin turbo straight six from the factory on your lighter BMW would be a monster.
Budget Boosting that would be perfect but and engine like that would cost a fortune where I live, I've probably bought a m40 and I'm going to just put a turbo and bigger injectors, not very special all I can afford tho thanks for your help :)
Back again. Decided to leave the Trans Am naturally aspirated, But I do have a 1973 Dodge Dart sport with a 225 slant 6. A buddy of mine was telling me to go with a Paxton supercharger but I also thought about a turbo setup. DO you have any suggestions or information to share as to what would be best for that slant 6? Wondering what my best course of action would be.
+number3665 The slant 6 would be a great custom turbo engine. A modified or custom made turbo header with a t3 or t4 flange to bolt on turbocharger to install the turbocharger where you have the best room. The blow through 4 barrel carburetor with carb hat to seal the boost blowing in the carb. The turbo slant 6 would have loads more torque which would really haul that Dart around.
Budget Boosting Thanks! I think I'll go with that. I'm going to do some more research and watch more of your videos. And that Dart is the lightest car I've ever owned at about 2900 lbs. just a little bit of power will send it screaming down the road.
I was under the impression that if you don't have a blow off valve all that happens is the excess charge just goes back through the exhaust, via internal wastegate? Idk never claimed to know it all, correct me if I'm wrong. I've owned a couple Cars that didn't have factory blow off valves, one being a Mitsubishi Starion or conquest tsi. Lol I actually owned 5 of those over the years. Like I was saying I always thought that's what the waste gate flapper was for.
2013 you had lots of Datsun Z cars around. In this video, was this an 8.3 low compression motor converted to boost. Or a flat top piston motor ? You don't see blow thu much then or now in 2020. Great info....thank you
So you don't suggest running a BOV? So you don't mind blowing your turbo to bits when you let off? You don't mind the dangerous situation of 'boost surge' where you let off and it doesn't immediately respond?
***** I take care of my turbochargers, monitor EGT, fuel pressure, boost pressure, regular oil changes with synthetic oils. No problem with any of my turbochargers. Most of my turbo cars do not have blow off valves, the blue 280zx custom turbo in the video you are commenting in DOES have a BOV.
Budget Boosting I'm referring to when you said that you don't need a BOV. The problem isn't immediate, but you'll ruin the turbo by breaking the one way bearing for the turbine which can shatter the casing, all cause because the pressure that was compressed by the turbo then won't all go into the cylinder, some will try to exit back out where it came in, that is why a BOV was designed and is implemented in every car that features a turbocharger. Then there's the boost surge when you let off the throttle because of the still compressed air, some goes back out the intake and some still goes into the cylinder which on a FI engine it will run lean.
***** Really depends on the size and type of the turbocharger. I usually do not run them and turbochargers are designed to be strong but they must be taken care of. Including idling down around 5 minutes before shutdown to ensure clean cooler oil is going through them. So many variables can cause a failed turbo. I have not seen lack of a blow off valve being the problem. It was caused by some other forms of turbocharger care neglect.
Are you using a fuel pressure regulator ? I thought buing this : Mallory Fuel Pressure Regulators 4309. And I if you are using an other pressure regulator, where do the tubing have to go ? Thx for answer :)
Lars T Yes I am using a bosch boost referencing fuel pressure regulator. We will make a video on fuel pressure regulator installation soon. Fuel source to in side arrow of fuel pressure regulator out arrow to carburetor or fuel rail, usually the bottom part of regulator port goes to return line, most regulators have arrows showing fuel flow in and out and RTN for the return line port. Intake manifold pressure/vacuum source to vacuum source fitting going to regulator. Once it is installed correctly, the adjustment port has nut to loosen, make adjustment to desired fuel pressure at idle with vacuum disconnected, plug vacuum in and watch fuel pressure gage and adjust after test driving as necessary for your desired fuel pressure/performance.
Lars T Also when shopping for fuel pressure regulator to use with turbo setup, make sure its a boost referenced fuel pressure regulator. Some regulators are just vacuum referenced which just work for natural aspirated engines.
thanks, well I hope you make a video about it :) because I need some guidens. And I am going to look upp on that boost referenced fuel pressure regulator
Lars T keep checking back on our new videos, should be out later this weekend. Until I make the new video, watch our Nissan z cars carburation conversion video, its not a turbo z however I do believe I go over the fuel pressure regulator installation a bit. The difference between the two is the vacuum and boost port, for turbo you use boost referenced regulator for N/A a vacuum referenced regulator. The installation is the same other than that.
Hi guys. I've got a datsun 120y. Was hoping to turbo whilst keeping the carby as I've never seen this done before. Money and time is not an issue for me. Just information. Any chance you guys could help me?
You'd probably get better performance to relocate the air filter to the grille area, its gotta be oullin in hot air in that spot. That bein said, im new to this style set up so thank you for the information!
how are you controling how much boost your making. I'm trying to turbo a Chevy s10 with a built 4.3 I'd like to run about 10psi on the street and 15psi at the track. do you use a manual valve in the system? if so where?
the boost is controlled by the wastegate which bypasses exhaust spinning the turbocharger when it reaches boost pressure that compresses spring inside wastegate. A controller can be connected to the wastegate to raise the boost higher than the spring's compression rate.
My god, these kids and their blow off valve beliefs... Good marketing from the bov companies have them all thinking they must have, and buy one or they will hurt their car..:) Thanks for all the good videos Budget, I appreciate the info your sharing with all of us.....keep em coming!
Ray Dolinger Right, they didn't grow up seeing turbo powered engines evolve like we did. From the 1965 Chevy Covair,H-6 draw through turbo, the 1978 Buick Sport Coupe Regal 3.8 draw through turbo V6, the 1980 Pontiac Trans Am Turbo 4.9 turbo, draw through V-8, 1980-1983 Datsun/Nissan 280zx turbo 2.8 straight six fuel injected turbo, 1984-1988 Nissan 300zx 3.0 turbo V-6, and many more. All those cars never had blow off valves and no turbo car I have seen had a blow off valve from the factory. A lot of them had relief valves to prevent overboosting engines when the internal wastegate rubber tubing disconnected or wastegate failure. Kids these days do not know the history of turbocharging, how it evolved into what it is today. Thank you again for watching.
Its not marketing it's a fact if your running less than 10psi then no a BOV may not absolutely necssary but get above 12psi and compressor stall is real and damages the compressor wheel over time. I've been involved since the days when turbos were all draw thru. I remember seeing a 68 camaro w/468 running twins drawing thru a 1050 dominator make god like power 850 on the dyno. but it was a mess to drive and a hot house flower only good? for drag racing turbo lag was measured in secounds as in 5 then it spooled like a light switch nothing, nothing ,OMG. It was a waste land none knew anything few guys running Offys at indy and some old vets from WWII with fighter plane experience. One was to small the other to big same for the turbos. It was all cut and paste with crutches and no cheap welders migs cost a couple of K tig was just not an option, Since they were draw thru one back fire could destroy everything or even kill you all the intake plumbing back to the intake inlet was filled with combustable mix big boom sharpnel and other pcs flying everywhere and direction.
roger depew I have a blow off valve on the Blow through carbureted 280zx car and it runs fine. I do not have one on my fuel injected 300zx turbo, using a budget friendly TO4e ebay turbocharger and run around 18 psi daily driving, runs great and reliable. Turbochargers that fail are for issues not related to lack of blow off valve use. They usually fail due to foreign object damage, no air cleaner, dirty contaminated or poor oil change schedule, not allowing the car to idle down for several minutes to allow hot oil in the bearings to cool down before shutdown. Most people just drive the car hard, avoid preventative maintenance, park and shut off the engine and wonder why their turbochargers fail. Many companies do capitalize from these failures and conveniently relate them to the lack of blow off valve use. Draw through turbocharging, you cannot reasonably use a blow off valve due to fuel and air released in the engine compartment when the valve opens. Honestly, a well made turbocharger is built to withstand very extreme heat and pressure forces and one that fails for some surging is really not a well built turbocharger. The 1984 though 1987 Buick GNX, Grand National, T-type series turbo regals boosted 15 psi stock and many increased the boost much higher. None of them ever had blow off valves from the factory and very few ever installed them or even heard of them in the 80's. I know of many people today still running the original 27 plus year old turbo Buicks with the original Garrett turbochargers still laying down competitive drag times and great daily driving cars as well. Many Nissan and Toyota turbo cars I tuned, drove and enjoyed in Japan did not have factory blow off valves in their cars and I drove them hard and they performed great and reliably. The above is the reason I made blow off valves, the truth video. I am one that does not believe the hype about blow off valves, I have had them on some cars, and not used them on others and honestly had no genuine need to. Its always up to the owner and the tuner of the engine to make that decision.
what is ur opinion on in closing the carb in a box for installing a turbo. plan on putting a 4.9 i6 in my 97 expedition n putting a turbo on it. not wanting much more than 5 lbs or so of boost. just want enuff power to pull a load
+Budget Boosting I remember seeing the people with the old import mini trucks running them. I just need enough to push a 4.9 ford i6 up to 250 hp n 300 ft lb torque.
+sketchyssk8shop You should have no problem, the torque and power on the inline six is great once it has enough carburetor. From the factory, many of those sixes were under carbureted with a very small 1 bbl. The larger 4 bbl. carb with some boost should meet your goals.
Ive got an 87 mustang, 306, b303, gt40p, 1.7 rr, performer intake, demon 650 carb, bbk shorty headers/ x pipe. Dropping the motor in thr car in 2 weeks. 1st ever car build. Will the gains over stock be notable? Im worried its not gonna be much more over stock. If nah then turbo is my next step but im just sketched bc these blocks are said to grenade at 500hp.
If your cam rpm power rating ( for example 2500-6500) is the same rpm rating as your intake manifold, your power, torque, and feel of your performance will increase greatly. Some have mismatched intake manifold power rating and cam power ratings and end up losing power. For example you have an intake manifold that puts 3500-7500 rpm power band with a 1500-6000 rpm power band cam, it will be mismatched and lose power. What you want is the cam power band the same as the power band rating of the intake manifold or as close as possible for best power rating. For turbocharging its a bit different since turbochargers tend to start pulling good at around 3000 rpm, so a cam and intake manifold rated for 3000-redline would be best for turbo setups.
I have a 400m ford v8. I'm sure you can't just pull oil and slap it together.... compression issues? More or less what would a rough price be for all the appropriate equipment?
Wyatt King The oil pressure sender or switch on the side of the block gets removed and a t fitting is installed to use the oil pressure switch and run the oil supply for turbocharger. The higher the compression of the engine, the less turbo boost you need to run to make good power, higher compression is also an advantage due to less turbo or boost lag so engine is more responsive off the line with high compression. Just takes better quality of fuel than the low octane pump gas to really benefit from the performance. Rough price for sourcing the turbo and upgrades would be around $2000 or less depending on the source. Thank you for watching and subscribing.
imagine that there exists people like this that gives you an honest respectable in depth video of something that you can actually learn from, i have a hard time learning things but i only had to watch this once
Idiot.
Knowledge is power great video
VERY useful car enthusiast information right here.

Took me hours searching to find good info like this, thank you!
The beginning of the video was good, the guy laughing in the back ground made it awesome, lol.
Very cool cars! I had several Datsun Z cars growing up. I always wanted to turbo them, but never had the time or money back then. Now Im working on a blow through system for my Studebaker 289 V8.. Stude was the pioneer of boost.

From a guy with no turbo experience whatsoever, I appreciated this video very much and it pointed me in the direction I was looking for.
I wanted to eventually run a super with a carb. Nice to see a UA-camr who finally talks about the ins and outs of running a blow through carb setup.
Although I drive an 86 z28, I still love watching informative stuff on cars, such as boosting. Awesome video, I'm not a forced induction expert, but I learned alot.

by far the best channel i’ve found
also where to get the air/fuel gauge?
This is an excellently put together and well explained video for blow through turbo. 🙌🙌
thanks,
it is indeed a budget boosting
you make really good videos! thanks for sharing the knowledge
I had no idea how carbs worked with turbos before this, thanks for the in depth description
DUDE...I had a 77 280z and would have gave my left nut to have that set up.
This was the best most simple, straight forward DIY how to on a budget even. Never know you could turbo a carbed motor. And compared to an EFI upgrade + turbo's it's a real budget build with big power potential. While retaining drivability.
starbattles1 Yes, I remember when I decided to go that route due to the stock fuel injection not handling the turbo set up very well. I went the blow through turbo route and I have liked that set up the best. I started with the Demon 650 blow through carb which was pretty good and eventually to the Quick fuel SS-650-BAN 4 barrel carburetor and I like it even more. I have the intake and exhaust manifolds off this Z car waiting for a custom twin turbo header which a friend of mine fabricated to fit two of my z cars which will fit any z from 1970-1983, all the L series inline sixes. It was fabricated to fit in these cars once the air conditioning compressor is removed and a few other things that are in the way for the twin turbo setup. To me no A/C is a small price to pay for a twin T04e powered L28 Z car. Once I get this new twin turbo header, I will get with my fabricator and he will start making them so we can sell them to others desiring twin turbo z cars. We will sell them on our budgetboosting ebay account where we currently sell our window stickers.
Love the wire intercooler mounts.
Best way to start a video❤
Fantastic video thank you sir. Boosted 65 mustang coupe in progress and this is a huge help in my planning process.
All Out Throttle awesome, boosted Mustangs fun to run. They are very popular at NMCA races in all classes. Would like to race that series in the future.
I almost jizzed in my pants when I saw all the z's. I miss mine alot. Thanks for info, the z's were an added bonus.
Bryant Arnold Thank you, Its great to have people that appreciate our work.
I have been referring to this video for years, thinking about various vehicles I've had over the years that had carbs on them. But I'm doing it finally. Putting a turbo on an old 85 dodge ramcharger with the 318. I'm hoping to get it done before a big trip to moab Utah next April
How is your project coming along?
@@ChinzySpecials uhh......😅 not so good. The weather got bad so I had to stop working on it for like 2 months. We got thw motor and trans in, and got the motor fired up for thw first time without the turbos, and then went to move it undernits own power for the first time, but something is wrong with the trans, so it has to come back out
@@garymaddux2000 haha I get that completely I'm doing a single turbo on a sbc. Got the turbo next is blow through carb and all the rest of the parts. Turbo kit will be made of pure exhaust tubing haha
@@ChinzySpecials I still need to get my turbo and blow through carb. Or I might go with an efi setup to make it simpler. For now, my headers just come up and point forward at where the radiator use to be lol.
@@garymaddux2000 haha I still have to gap the rings haha got the turbo engine all apart in my shop haha. The truck is under a snowbank lol. But I'm just throwing pretty much using every paycheck for parts haha. Easy to do when you are 18 lol. But let's of projects as it it
Thanks man for explaining this so easily
It’s the exact engine I’m looking to turbo awesome vid
plan on doing this to my 521 stroker in my truck cant wait to see the results gonna be a damn monster
Austin Hermann Outstanding, do make sure you have the great assortment of gages to monitor all the engine perimeters that will change when adding boost to an already strong engine.
Thanks a lot a light bulb went off in my head when you mentioned the T connection for the oil supply. I just realized that engine oil is under pressure from the oil pump so all you have to do is tap into that pressurized oil and it will be pushed into the turbo... I used to be confused as to how turbos got fed with oil O thought maybe the turbo has a pump inside that pulls oil from the oil pan or there's gravity feeding but none of those sound like they would work.
Huh, I have a 280zx with an L28 EFI. I thought that you HAD to go Megasquirt, big injectors, T3 and whatnot. But this looks very interesting.... I’ve never seen a carbureted car that is also turbocharged. Thank you for introducing this route to me. I’m considering this now that I see it.
The carburetor is designed for boost blow thru. It is a quick fuel 650-BAN www.summitracing.com/parts/QFT-Q650-BAN.
This carburetor with an arizona Z 4 bbl intake manifold will allow boost thru carb without complicated fuel injection systems. arizonazcar.com/engine
@@budgetboosting cool. Is there a difference between 650,750 or 950 other than price?
Going to boost my Carb’d 4AC Toyota Corolla thanks to you
This video was awesome thank you for posting 🙏
Blowoff* valves aren't necessary, but bypass valves in general, yes, ALWAYS run one on a boosted gasoline setup. Important tip: a blowoff valve is a specific type of bypass valve. I know stock tuning sometimes won't compensate quite correctly for a true blowoff valve [versus a stock bypass valve], but running a full on blowoff valve is undeniably safer than having no bypass at all. When the throttle plate closes under boost, if there's no bypass valve, that pressurized air has nowhere to go but back out through the turbocharger, in the wrong direction. Even if it doesn't literally cause the turbo to momentarily spin backwards, it can still mechanically stress the turbo unnecessarily. Overall good video though. Always run some sort of bypass valve on your turbocharged gasoline engine.
Great video! I'm looking at buying an Lseries motor to rebuild and potentially use, which ones are the ones to have? TIA
Your in with this here,and thanks for a brief explanation of how the thing works I've studied little about the systems but always held interest in the older cars run with much electronic assist.
arthur clark Yes the older cars really benefit from turbocharging. I see many old monstrous twin turbo Camaros, Corvettes, Mustangs and many others blow through the traps and very high speeds and very low times at Top Gun Raceway.
back pressure is not considered from the point of bottom dead center but again the boast adds pressure the cylinder should test positive for vacuum if valve timing is correct likely in most of the older cars it's not as tight or correctly timed when it is the turbo is likely larger than normal
arthur clark At idle a turbo engine will see its normal vacuum, as load is added to the engine and boost increases, vacuum will become positive pressure so having the stock vacuum advance will not benefit the older vehicles. I removed the vacuum from my electronic distributor so it is a constant and no adjustment on vacuum. I also install a boost referenced fuel pressure regulator that ensures fuel pressure rises as boost rises. When much larger turbochargers are installed, usable boost will take longer to build up and directly reflect negative vacuum and boost pressures. One way valves or breathers should be installed to ensure boost does not pressurize the valve covers or engine block. Lots of things to consider when turbocharging a non-turbo car. Its quite the adventure though.
def thanks for this video, dont know much about turbos and u cleared up alot in a shirt matter of time.. now ima turbo my foxbody
Terry Lewis Nice, lots of aftermarket support for fox body mustangs and many have been successfully turbocharged to very monstrous proportions. I really like the foxbody and its potential. Thank you for watching. I made 4 new videos and two of them are related to turbo conversions.
Most def! Thanks again
all done? how did it run?
Do you need a boost reference for fuel pressure with that carb? What's a good starting point for fuel pressure for it? Thanks!
I’m building a 91 Isuzu 2.3 turbo. Trying to find a decent manifold that’s not 700.00. Geminiturbo had a nice manifold and other than stock all I can find. Thanks for the info. Hopefully by mid summer I’ll be boosted!
You could have an adapter flange made with a T3 turbo flange and a custom made bolt on adapter for your intake manifold to run a holley style blow through carb.
very helpful and educational good stuff
you just got yourself a new sub...love your shit..
Ghosty wun Thank you for the comments and thank you for watching. Happy boosting !
Really well explained.
Awesome vid
what in the grown ass jimmy newtron shit is going on here lol love it
Hello sir can i use a standard N/A carb in conjunction with a turbo? i can see you are using a well made turbo carb. thanks.
Sorry I'm late to the party, but you can use a standard carb in two ways. Firstly isn't so easy (unless it's fairly commonly done with that model of carb for example SU carbs), seal up any vents/throttle shafts etc and find a way of venting the float bowl as well as being able to pressurise it on boost. *Second & much easier* but less tidy maybe is if you build the whole carb into a plenum chamber. This means the whole carb inside and out sees boost and thus no excess pressure is put on it. You then only need to seal up the point the throttle cable and fuel line enter, just make sure to use a linear fuel pressure regulator with the plenum set up so that your fuel pressure stays at the correct level relative to the boost rather than the boost overcoming the fuel pressure causing the car to lean out.
How the hell are you going to say building a boost box for a carb is easier than $50 worth of mods that anyone can do in a day to any Holley carb easier ? To the original poster if you haven't already bought a blow through there's a right up by hanger18. Not everything listed is necessary unless your making 18psi plus. I have built 3 Holley blow through carbs for around $50 each. But the most mine have seen is 15psi.
no
great video, rare one indeed
Great job. I wish you were my neighbor. Does this type of system cause problems in this car?
Move on over man the more the merrier
I thought I had a Z problem lol. keep it up, good to see another blowthrough z running around. my blowthrough setup is using triple side drafts, but this is what i was planing to do had i not found all the parts. great video!
Like z cars, even like them more turbocharged and carburated.
Budget Boosting I believe I found your website with the old HKS triple deuce blow through turbo kit. I have always liked that kit ever since I saw it in Japan on an S130z with twin TD06 turbochargers on a 3.1 stroker. That car was wicked and that kit is severely hard to find. In the states Jim Cook Racing used to sell the Cartech triple weber side draft complete kit including a T04 turbocharger, external wastegates, intercooler and all the tubing and bolt ups necessary for installation for around $3500. If only those complete kits were still for sale, that company would make a fortune since there are many old Z enthusiests than there were then..... I like the HKS set up you installed, since you were running rich, a much larger turbocharger would fix that, somewhere around a T70 with ball bearing, 15-20 lbs of boost, 100 octane fuel and you would be golden.
I like this video coz its simple, easy to understand and gave all da info i needed!! Good work guys! U have a subscriber now!!!
Outstanding, thank you, it is our goal to share what we have learned and see others accomplish this great technique on their fun cars.
I love the sound of those Z’s
The cardboard gauge holder is a nice touch! Did you paint it blue or did the cardboard come that way?
perfect perfect video bro , perfectly explained 💪💥🤘🏍️
You've cleared a lot of things up for me!!
This video Literally just save me like $700 thank you
No worries man, good to hear the video's are having real world applications to people.
Nice job on the blow thru setup!! I had a 79 280zx I converted to turbo but kept the EFI and it was a pain to get enough fuel to the engine at higher boost levels so I ended up using hobbs switches and extra injectors to feed it enough. Detonation was always a problem until I replaced the distributer and ecu with ones from a turbo car, then I used water injection at higher boost levels to prevent detonation. Now I got an 86 4x4 Nissan pickup with a 2.4 liter 4 banger and I'm planning a blow thru setup using a t3/t4 hybred turbo and intercooler fed into a Holley 350 2 barrel that's been prepped internally for turbo use with a boost referenced power valve and pitot tube on the bowl vent to keep a positive pressure in the bowl along with an EFI fuel pump and aeromotive boost sensing regulator. I have all the parts gathered up and ready now but need to get a smaller power brake booster since the turbo won't fit in there with the stock booster.
SuperDaveZilla I also first tried the fuel injection on my 79 and the fuel delivery had issues and that is what led to my using the blow through setup. I even ran the MAF sensor in the boost path just prior to the intake manifold so the MAF directly adjusted to boost but even that was not enough fuel delivery for boost and the low octane pump gas. Found that the blow through set up works well and will even work with the pump gas as long as the boost is not too high. Thank you for watching and look forward to some pictures of the Nissan 4x4 truck blow through when its done.
Im gonna use this idea on my bobber, be fun to try
you my friend have gotten a subscriber. hope you still do more videos
This car is awesome, Safety wire and zip ties make anything possible.
thanks for those videos man , im learning alot from them :D
Yeah great video.. Guy is a great teacher.. should be working at ITT Tech!
KFLY67 Thank you, I had instructing and facilitating experience teaching my fellow military personnel during various times in my 21 year career.
Great video and alot of useful information 👍
I forgot where your other video regarding the fuel pressure regulator, but i'm going to post this here. In your fuel pressure regulator video you said you had one for boost, yet they also make one for vacuum. So, in my vehicle which runs a carb but not any boost, would it be practical to put a vacuum controlled fuel pressure regulator to keep my carburetor with fuel?
Most adjust the boost referenced power valve circuit...for fuel enrichment
Dude, you are awesome, thanks!
Do you need an intercooler? I read some suggesting it will run better without since the fuel will mix better with air at higher temp and the boost isn't high enough that temp will be a problem.
Mmm perfect for my project I have 1987 mazda b2000 truck but is a carburetor I never thought u can boosted time to work on it if I have any questions hope you can give me some ideas or information thanks
No cane!!! Good job man awesome progress!!!
Its an older video
+Budget Boosting do you have a video with a carburetor enclosure
the blow through carburetor video has a 4 barrel carburetor enclosure. It is not a large enclosure but designed for blow through application.
Freaking fantastic you talk everything love it!
Like the idea... how much boost do run? I own 71 240z with l28et on megasquirt... the cost of your Demon carburetor was about the cost of megasquirt standalone.
There is spring in blow off valve what you can usually adjust tighter and it isn't open with low boost if is it adjust hard. you can hear tsuhhh sound when it's open and there isn't thad sound.
johanijohani yes the ones that have the adjustable spring are the best type.
Was it a l28 turbo before the blow through carb or if not what internals are you running
Holy crap. This is amazing.
What if the turbo used for 110cc carburetor bike? how the placement like? Is it from turbo to carburetor and then to the engine, or from carburetor to turbo then to the engine?
Awesome 👍 Thanks. Always wondered.
Very informative. I am considering building one. Currently,I have a 496ci BBC that is highly modified. I run a Dominator 1050.
It has annulars. I can't use it with turbos,... right?
Do you recommend air to air or a water to air intercooler?
is the blow off valve responsible for the flutter sound?
Cool learned a few new things, thanks
Couple questions. WHat boost is the carb capable of handling? As much as large jets allow? How much boost have you got it to so far?
I will be doing this on a 351 Cleveland. Any thoughts or suggestions?
starbattles1 I was running around 18 pounds of boost. It should support 21 pounds just fine and jetting and other factors such as fuel octane and timing also will help increase or limit boost ranges. I am considering turbocharging my 1989 F250 4x4 with the 351 Winsor V-8 in the future when my other cars get done....
hi Matt, so where is the best place to put an external wastegage on a turbo setup is it between the exhaust manifold flange and turbocharger.also what exhaust manifold you used for your setup.did you use a datsun 280zx turbo manifold?
f rod best place for ext wastegate is at the end of the exh manifold just before turbo flange or between exhaust manifold and turbo flange. I used a Nissan 280 zx turbo exhaust manifold I found on ebay. Some turbochargers have provisions on the exhaust housing for external waste gates. I have seen them as options on turbonetics turbochargers.
oh ok I see.I saw a wastegate adapter in ebay.I wanted to know if I can use that adapter to mount a wastegate without having to cut and weld tubing to add a wastegate.Let me know if you think that will work.
www.ebay.com/itm/Progate-T4-Wastegate-Adapter-/171391515044?pt=Motors_Car_Truck_Parts_Accessories&hash=item27e7baf9a4&vxp=mtr
f rod that adapter looks good. Its a t3 to t4 with external waste gate hook up. Just need a t4 turbo like a gt45, t04b or any turbocharger with the t4 flange to fit the adapter.
All those Datsuns .. I have a couple . My brother has one with 350 , lowered ,nitrous , flares , anyway thanks for showing the turbo , I want to put one on my c10
What intake and turbo exhaust are you using???
Need to know please!!!!
Hey man, nice video. Going to do a blow through carb lt1 and had some questions. If you remember.... how much boost were you running ? Did you ever need to get a brpv ? Thanks.
Great video, enjoyed and very informative
nica8487 Thank you for your comments and watching, glad you like them. We will continue.
what brand of turbos do you normally run? I wasn't sure if you mentioned in the video
How much did you have to go uo on your primary and secondary jets, Thanks, nice build!!!!
I believe I went 68 primary and 66 secondary, its been a while since I did it.
would you have to advance your ignition as well? would you not only have to change the idle ignition timing but also how fast it changes and the WOT ignition timing? how would you know how much to do it? and how would you go about it? by modifying the distributor? i have a bmw m10b18 not whatever this car is by the way
Budget Boosting what are these devices called? the ones to control timing, are they sort of like an FMU but for timing? my main problem at the moment is i live in europe and the only blow through carbs i can find are from america, expensive and then i have to have them shipped on top and maybe pay tax, and as they dont even sell them here i cant see it being easy to find one second hand. i might have to give up on this which is a shame as a boosted, carbed 4 cylinder would be fairly rare thing to see, and really cheap to buy replacement engines for and such. might just have to engine swap to something with fuel injection and do that :( sounds so boring compared to boosting a m10, would be like my own version of a 2002 xD other option is to try megasquirt the carbed engine, but for that money i could just buy a fuel injected one. i suppose i gotta choose easy, cheap and boring. or hard, expensive and epic xD
+Charlie Ward would be real neat if you could find a used 335i engine, they are well over 300 hp 300 lb torque twin turbo straight six from the factory on your lighter BMW would be a monster.
Budget Boosting that would be perfect but and engine like that would cost a fortune where I live, I've probably bought a m40 and I'm going to just put a turbo and bigger injectors, not very special all I can afford tho thanks for your help :)
Back again. Decided to leave the Trans Am naturally aspirated, But I do have a 1973 Dodge Dart sport with a 225 slant 6. A buddy of mine was telling me to go with a Paxton supercharger but I also thought about a turbo setup. DO you have any suggestions or information to share as to what would be best for that slant 6? Wondering what my best course of action would be.
+number3665 The slant 6 would be a great custom turbo engine. A modified or custom made turbo header with a t3 or t4 flange to bolt on turbocharger to install the turbocharger where you have the best room. The blow through 4 barrel carburetor with carb hat to seal the boost blowing in the carb. The turbo slant 6 would have loads more torque which would really haul that Dart around.
Budget Boosting Thanks! I think I'll go with that. I'm going to do some more research and watch more of your videos. And that Dart is the lightest car I've ever owned at about 2900 lbs. just a little bit of power will send it screaming down the road.
I'm looking for a blowthrough carb that will work on my 1.5l tercel, any advise?
I was under the impression that if you don't have a blow off valve all that happens is the excess charge just goes back through the exhaust, via internal wastegate? Idk never claimed to know it all, correct me if I'm wrong. I've owned a couple Cars that didn't have factory blow off valves, one being a Mitsubishi Starion or conquest tsi. Lol I actually owned 5 of those over the years. Like I was saying I always thought that's what the waste gate flapper was for.
2013 you had lots of Datsun Z cars around.
In this video, was this an 8.3 low compression motor converted to boost. Or a flat top piston motor ?
You don't see blow thu much then or now in 2020.
Great info....thank you
Holy shit I'm so godamn jealous, the 240-80z are my favorite cars, mainly the 240z
wish i had found you guys earlier !
So you don't suggest running a BOV? So you don't mind blowing your turbo to bits when you let off? You don't mind the dangerous situation of 'boost surge' where you let off and it doesn't immediately respond?
***** I take care of my turbochargers, monitor EGT, fuel pressure, boost pressure, regular oil changes with synthetic oils. No problem with any of my turbochargers. Most of my turbo cars do not have blow off valves, the blue 280zx custom turbo in the video you are commenting in DOES have a BOV.
Budget Boosting I'm referring to when you said that you don't need a BOV. The problem isn't immediate, but you'll ruin the turbo by breaking the one way bearing for the turbine which can shatter the casing, all cause because the pressure that was compressed by the turbo then won't all go into the cylinder, some will try to exit back out where it came in, that is why a BOV was designed and is implemented in every car that features a turbocharger. Then there's the boost surge when you let off the throttle because of the still compressed air, some goes back out the intake and some still goes into the cylinder which on a FI engine it will run lean.
***** Really depends on the size and type of the turbocharger. I usually do not run them and turbochargers are designed to be strong but they must be taken care of. Including idling down around 5 minutes before shutdown to ensure clean cooler oil is going through them. So many variables can cause a failed turbo. I have not seen lack of a blow off valve being the problem. It was caused by some other forms of turbocharger care neglect.
What would be a good size carb for a Toyota 22r for a blow through set up?
Are you using a fuel pressure regulator ? I thought buing this : Mallory Fuel Pressure Regulators 4309. And I if you are using an other pressure regulator, where do the tubing have to go ? Thx for answer :)
Lars T Yes I am using a bosch boost referencing fuel pressure regulator. We will make a video on fuel pressure regulator installation soon. Fuel source to in side arrow of fuel pressure regulator out arrow to carburetor or fuel rail, usually the bottom part of regulator port goes to return line, most regulators have arrows showing fuel flow in and out and RTN for the return line port. Intake manifold pressure/vacuum source to vacuum source fitting going to regulator. Once it is installed correctly, the adjustment port has nut to loosen, make adjustment to desired fuel pressure at idle with vacuum disconnected, plug vacuum in and watch fuel pressure gage and adjust after test driving as necessary for your desired fuel pressure/performance.
Lars T Also when shopping for fuel pressure regulator to use with turbo setup, make sure its a boost referenced fuel pressure regulator. Some regulators are just vacuum referenced which just work for natural aspirated engines.
thanks, well I hope you make a video about it :) because I need some guidens. And I am going to look upp on that boost referenced fuel pressure regulator
Lars T keep checking back on our new videos, should be out later this weekend. Until I make the new video, watch our Nissan z cars carburation conversion video, its not a turbo z however I do believe I go over the fuel pressure regulator installation a bit. The difference between the two is the vacuum and boost port, for turbo you use boost referenced regulator for N/A a vacuum referenced regulator. The installation is the same other than that.
Hi guys. I've got a datsun 120y. Was hoping to turbo whilst keeping the carby as I've never seen this done before. Money and time is not an issue for me. Just information. Any chance you guys could help me?
If kitami-jun was American
You'd probably get better performance to relocate the air filter to the grille area, its gotta be oullin in hot air in that spot. That bein said, im new to this style set up so thank you for the information!
how are you controling how much boost your making. I'm trying to turbo a Chevy s10 with a built 4.3 I'd like to run about 10psi on the street and 15psi at the track. do you use a manual valve in the system? if so where?
wastegate spring and blow off valve perhaps?
the boost is controlled by the wastegate which bypasses exhaust spinning the turbocharger when it reaches boost pressure that compresses spring inside wastegate. A controller can be connected to the wastegate to raise the boost higher than the spring's compression rate.
I need help ! I got a 4G33 engine in my car (4 cylinder inline gasoline) with carb, can i turbocharge it?
Love the gauge pod lol 😂
My god, these kids and their blow off valve beliefs... Good marketing from the bov companies have them all thinking they must have, and buy one or they will hurt their car..:) Thanks for all the good videos Budget, I appreciate the info your sharing with all of us.....keep em coming!
Ray Dolinger Right, they didn't grow up seeing turbo powered engines evolve like we did. From the 1965 Chevy Covair,H-6 draw through turbo, the 1978 Buick Sport Coupe Regal 3.8 draw through turbo V6, the 1980 Pontiac Trans Am Turbo 4.9 turbo, draw through V-8, 1980-1983 Datsun/Nissan 280zx turbo 2.8 straight six fuel injected turbo, 1984-1988 Nissan 300zx 3.0 turbo V-6, and many more. All those cars never had blow off valves and no turbo car I have seen had a blow off valve from the factory. A lot of them had relief valves to prevent overboosting engines when the internal wastegate rubber tubing disconnected or wastegate failure. Kids these days do not know the history of turbocharging, how it evolved into what it is today. Thank you again for watching.
Its not marketing it's a fact if your running less than 10psi then no a BOV may not absolutely necssary but get above 12psi and compressor stall is real and damages the compressor wheel over time. I've been involved since the days when turbos were all draw thru. I remember seeing a 68 camaro w/468 running twins drawing thru a 1050 dominator make god like power 850 on the dyno. but it was a mess to drive and a hot house flower only good? for drag racing turbo lag was measured in secounds as in 5 then it spooled like a light switch nothing, nothing ,OMG. It was a waste land none knew anything few guys running Offys at indy and some old vets from WWII with fighter plane experience. One was to small the other to big same for the turbos. It was all cut and paste with crutches and no cheap welders migs cost a couple of K tig was just not an option, Since they were draw thru one back fire could destroy everything or even kill you all the intake plumbing back to the intake inlet was filled with combustable mix big boom sharpnel and other pcs flying everywhere and direction.
roger depew I have a blow off valve on the Blow through carbureted 280zx car and it runs fine. I do not have one on my fuel injected 300zx turbo, using a budget friendly TO4e ebay turbocharger and run around 18 psi daily driving, runs great and reliable. Turbochargers that fail are for issues not related to lack of blow off valve use. They usually fail due to foreign object damage, no air cleaner, dirty contaminated or poor oil change schedule, not allowing the car to idle down for several minutes to allow hot oil in the bearings to cool down before shutdown. Most people just drive the car hard, avoid preventative maintenance, park and shut off the engine and wonder why their turbochargers fail. Many companies do capitalize from these failures and conveniently relate them to the lack of blow off valve use. Draw through turbocharging, you cannot reasonably use a blow off valve due to fuel and air released in the engine compartment when the valve opens. Honestly, a well made turbocharger is built to withstand very extreme heat and pressure forces and one that fails for some surging is really not a well built turbocharger. The 1984 though 1987 Buick GNX, Grand National, T-type series turbo regals boosted 15 psi stock and many increased the boost much higher. None of them ever had blow off valves from the factory and very few ever installed them or even heard of them in the 80's. I know of many people today still running the original 27 plus year old turbo Buicks with the original Garrett turbochargers still laying down competitive drag times and great daily driving cars as well. Many Nissan and Toyota turbo cars I tuned, drove and enjoyed in Japan did not have factory blow off valves in their cars and I drove them hard and they performed great and reliably. The above is the reason I made blow off valves, the truth video. I am one that does not believe the hype about blow off valves, I have had them on some cars, and not used them on others and honestly had no genuine need to. Its always up to the owner and the tuner of the engine to make that decision.
what is ur opinion on in closing the carb in a box for installing a turbo. plan on putting a 4.9 i6 in my 97 expedition n putting a turbo on it. not wanting much more than 5 lbs or so of boost. just want enuff power to pull a load
+sketchyssk8shop that should work fine for low boost.
+Budget Boosting I remember seeing the people with the old import mini trucks running them. I just need enough to push a 4.9 ford i6 up to 250 hp n 300 ft lb torque.
+sketchyssk8shop You should have no problem, the torque and power on the inline six is great once it has enough carburetor. From the factory, many of those sixes were under carbureted with a very small 1 bbl. The larger 4 bbl. carb with some boost should meet your goals.
I'm thinking of doing this on my B2200
Thanks man your video was very helpful. I'm about to attempt this on a 86 Monte Carlo with a stock HO 305. Gonna order a twin turbo kit from eBay.
Kevin Williams That should be a beast, Summit sells great Quick fuel blow through SS-650-BAN carb.
Awesome. Thanks
@@KevinWilliams-px6il it will be an awesome grenade.take lots of video when you run it/blow it up
Ive got an 87 mustang, 306, b303, gt40p, 1.7 rr, performer intake, demon 650 carb, bbk shorty headers/ x pipe. Dropping the motor in thr car in 2 weeks. 1st ever car build. Will the gains over stock be notable? Im worried its not gonna be much more over stock. If nah then turbo is my next step but im just sketched bc these blocks are said to grenade at 500hp.
If your cam rpm power rating ( for example 2500-6500) is the same rpm rating as your intake manifold, your power, torque, and feel of your performance will increase greatly. Some have mismatched intake manifold power rating and cam power ratings and end up losing power. For example you have an intake manifold that puts 3500-7500 rpm power band with a 1500-6000 rpm power band cam, it will be mismatched and lose power. What you want is the cam power band the same as the power band rating of the intake manifold or as close as possible for best power rating. For turbocharging its a bit different since turbochargers tend to start pulling good at around 3000 rpm, so a cam and intake manifold rated for 3000-redline would be best for turbo setups.
I have a 400m ford v8. I'm sure you can't just pull oil and slap it together.... compression issues? More or less what would a rough price be for all the appropriate equipment?

Wyatt King The oil pressure sender or switch on the side of the block gets removed and a t fitting is installed to use the oil pressure switch and run the oil supply for turbocharger. The higher the compression of the engine, the less turbo boost you need to run to make good power, higher compression is also an advantage due to less turbo or boost lag so engine is more responsive off the line with high compression. Just takes better quality of fuel than the low octane pump gas to really benefit from the performance. Rough price for sourcing the turbo and upgrades would be around $2000 or less depending on the source. Thank you for watching and subscribing.
