- Check out this Intercooler loss and how blow thru carb work!
Dang video!!!!
it was a 250HP difference in the intercooler, sorry I did not say it I only showed it @ 8:07. and accidentally deleted part of video and voice volume is terrible
I'm glad Steve is making more videos now. I love his content and I get a lot of value from it.
Ok
I've said it once, I'll say it again, Steve is The Man!
That is a ton of power on a Boosted Small Block Chevy!
Yes NO doubt .. But I'm really sorry but Steve might wanna go have his aggitts checked out what with his Malfunctioning DNA running around out there like He gives a shit when clearly he does NOT..Genome
Your discussion on Carburetors was spot on. Too many time no one will touch one because they don’t understand them. I’m one of the few in my area that can repair and rebuild most carburetors but I get paid well to do them.
Thank you for sharing your knowledge with us. No, I'm not planning on building anything like this but you answered a question regarding how much Jetting and how the fuel delivery is accomplished. You're a good man Mr. Steve!
Nice job on explaining the carb and how it functions with boost (power valves). Way back when,I started out with thermo quad carbs. Everything took off from there. Amazing how bits and pieces of different designs have been engineered to fit together over the years. Pretty much the same for most components.
For all the folks looking for the difference between the 2 intercoolers look at the graph @8:15. Run #9 made 1556@8000 with the air to air and run #11 made 1795@8000 with the air to wadder...
Thanks, was wondering 👍👊🇺🇸🤘
Thanks for that!!
Drop the t and say pop and that’s how you know you’re from Michigan
@@pimpdaddy9604 Its watter down in Fl. They even spell it that way.

Watter to air! Love your videos, Steve
I appreciate your ability to express yourself without the use of profanity! Thank you for all your help!!! Is there a video, or a price list somewhere? I'd love for you to build me a drive & drag sbc? N/A!
The biggest problem of that A/A intercooler was the size. To compare different style of cooling, at least the pipe diameter should be the same. On a high volume (+5l) engines, pipe diameter is crucial to keep the air flow cold and steady.
Mr Steve you are my super hero! I' have learned more in 2 months watching your videos all day long than I did hands on. I can't wait to see if my f2 blow threw runs like that. By the way my wife hates ya lol
Love my Steve tech wait a minute Your Steve tech. Same Name same mission extract the horses out of the barn. Just saw KSR and had your Motor in Will's car super cool. If people want evidence you have them all over the country. Making tracks its out there. Thanks for sharing. Steve!
I run Q16 in a 400HP Yamaha sidewinder, it did pick up a hundred rpm and had to clutch accordingly over C16. Great video 👍
250 HP difference thats huge so for the people with air to air like me stand a big HP gain with the water cooler ❤!!! Got to love the data and for free thanks so much for all your up loads !!
Good stuff. Old school is awesome. You are an aweome presenter. I Love the old big block bow tie 427. Small block is famous but gotta love the Ole 427 of late 60s early 70s.
Steve is OG blow thru guru! Good vid!
Great video. Really like the old school way with the carb. I want to go to the track and have it be simple and enjoy the day. Not to be stuck on a lab top all day.
Yeah me and my dad had a 871 blower on a true 350 and we had to quad keyed the crank and we still spun the pulley after a few hard street drives the tech has changed so much in 15 years
I had a 1980 Ford Mustang with the 2.3 l draw through turbo charger setup. I took the original 230 CFM carburetor off of it and put on a Holley 2 Barrel 500 CFM carburetor. Reported the intake manifold, they hadn't, I had a 1.75 inch exhaust manifold with a custom two and a half inch exhaust that ran up to the turbocharger, and he's 3 in exhaust from the turbocharger back to behind the car. It was the stock block with the forge flat top pistons running 9 to 1 compression ratio. On pump gas at 10 lb of boost it dynoed at 230 horsepower to the wheels. With the Boost unregulated, I could run 110 Octane leaded gasoline between 18 and 22 lb of boost is what it got but I never got a chance to put it on the chassis dyno it at that level but it was certainly faster!
That was the draw through, or wet turbocharger. It made some really cool noises at Full Throttle and between gears off the throttle you could actually hear this turbocharger speeding up with a little spanking boost when you'd first hit the throttle.
well Steve , once again you're schooling us wisely on the things that matter
i really appreciate the stuff you teach .!
I love the simplicity of this set up.
Been waiting for this love boost on carb content, budget guys need all info we can get
Thanks for sharing your secrets not a lot of guys would do it
glad you came into the cleetus world
So you left the shop with Kindergarteners in charge they couldn't even perform a simple intercooler connection and walked away saying nailed it ..Bravo steve Bravo
Man do I love this!!! Could you do a build breakdown on this!? This is like my dream setup honestly!
We use wander here in the Carolinas. All your videos are great, Thanks for all you do
I wonder/hope Billy and the old man from SRC will see this and learn anything from it. After watching this, I see why Billy is hesitant to switch the truck, and ‘maybe’ why he ran I to trouble switching carbs and running meth. Another great video Steve 👍👊🇺🇸🤘
SRC absolutely love the channel cool family making awesome content
I think Billy said one he would switch to EFI but he's gonna learn how to tune EFI on the Falcon and other things before he makes the switch. As good as the old man is working and tuning carburetors I probably would just stay carburetor but that's just me.
Didn't that carb have something stuck shut?
my goodness, the amount of knowledge gained... pure gems here. aired out any questions i had. 💎🔥
Spreading the knowledge!
Have not seen the modified air / fuel metering, including four floats, for a Holley, (you referred to the carb. by another name, did not catch the name), very interesting video. Thank you. Personally seeing where car owners are moving towards cold flowing *alcohol* with additives, and / or some sort of cold-air-flowing - modified fuel, running no external air cooler. The 90 degree restrictive elbows / turns, within the pushed air flow path, makes so much logical sense, *thanks again* .
Carb shop I think he said. im not sure there around anymore.
On the Carb. I built alot of Q-Jets when I was younger. I noticed GM used the same jetting alot of times between te BBCand SBC. It took awhile to figure that one out especially when I found out that my 500 Cadillac had the smallest jets GM made. Of course 3500 RPM was it on a stock one
I’ve already watched your other Steve-Tech videos on your dyno setup (surprising and interesting) but I’d like to see the console/operator perspective in a video at some point. Thanks for all the great info 👍👊🇺🇸🤘
Also interested to see the pressurised carb' setup. Back in the late 80's I bought an old (even then) Kawasaki Z1R Turbo with a pressurised carb and pressurised pre turbo water injection. The carb worked because the float bowl was pressurised by a feed from the inlet. Meaning that its internal pressure and float bowl pressure is near enough the same, leaving the carb to work as normal. The water injection tank was also pressurised from the inlet and fed the turbo intake via a jet with a spring valved jet set to open when the water, and boost pressure reached about 9 psi. I had a lot of fun with it, but that basic Bendix carb did not work well at low boost and it would fowl plugs and run like a dog. But on boost it could really clear it's throat and scare the cr?p out of me as it had way more power than chassis or brakes. The water injection worked as the one time I blew a hole in a piston (yes #2 always #2!) I discovered the water tank was empty.... Just remembering what a beast it was has me smiling now.
I bet that was a sweet bike. Thank you for the story.
Z1R TCs all came with a draw through Bendix. Turbo was the mini Rajay made by Shelby Spearco specially for use in the American Turbo Pack kit for the 1980 Volkswagen Diesel Rabbit Pickup. Turbo was noteworthy for only having labyrinth compressor seals which are specifically NOT to be used with a draw through carb. So somebody changed it before you got it, I guess.
@@patrickshaw8595 I am sure you are right. In truth the bike I had was a curious selection of parts, not all of which were original. I had thought it was based on a Z1000 with the Z1R fairing added but why then add the cae operated remote front brake reservoir?
@@richarddoyle689 Believe me buddy - I have "hottrodded" and "Frankensteined" everything from pencil sharpeners to 1950s aerial target drones. Somebody had a lot of good clean fun building that death trap, err - I mean motorcycle, lol.
I built the world's quickest SS 1/4 mi. gasoline-fueled motorcycle in 1980. It had a V8 outboard 2-stroke, water/steam-cooled centrifugal clutch, a parachute and very little else : D
Richard, I have been building Draw Thru Turbocharged/Supercharged motorcycles since the late 70z, and to this very day, inline 4 and
V twin, get rid of the Bendix and you'll truly enjoy life like never before. Nothing negative towards you and or the mods to the carb Sir, but with the Bendix, you leave a LOT on the table, h.p./torque and most importantly, drive ability.
T.S. RACING
awesome video Steve
thanks for explaining blow thru carb set ups
I would have found it to be more useful to see like for like pulls with water to air and air to air. It's kind of a no brainer that an undersized intercooler of any type would perform poorly. Perhaps you could do that comparison sometime in the future.
Good to see Steve do some stuff on traditionals
Anyone looking for or wanting more power than 2k through a blow through carb deserves associated issues. Talking like prior 1900’s technology evolved into the 21st century and it can support up to that much Hp. Your nuts! Very impressive capabilities of antique dinosaur technology. I’m only making like 650 hp with a blow through sbm, and I’m impressed with that lol. Never could imagine this kind of power with a carb…
That’s awesome all of your videos are great!!! You are the KING of HP👍
Gen 1 SBC Greatness----------love it!
I like the bowling alley bench. The best benches there are period. Get it now if you can.
Awesome information, we all appreciate your knowledge, and big hp videos steve,,,blazing tires,all the time
lots of know how in this one. thanks steve
Love me some blow through action.. cheers mate from Brisbane Australia
Congrats on your motor in Mullet winning drag week
I still have love for the "dinosaur bowls" and had many great memories using them. It's hard to beat what a good standalone will do. Awesome video!
If forgetting the fuel pump is the worst thing that happens today, it'll be a great afternoon. Haha
As always - interesting stuff. CHEERS from AUSTRALIA.
That's one badazz small block Chevy!!!
Sooooo, wadder is a Michigan thing? 😂 love the knowledge Steve, thanks for all the videos!
Nope, I say it the same. Pa. Haha!
love me some Q16. it'll take ur breath away if you get a wiff of it on a hot summer day. oxygenated fuel, 🤪 always ran Q16 in my naturally aspirated BBC because it made more power on the dyno and was trying to get everything we could out of it. Was truck pulling in a class that had to be all cast iron heads and intake.
Was going to ask about the air to air run numbers but I see in the comments the answer. A FYI a 90* bend has the same restriction as 160' of straight run. So your set up of 6 elbows is the same as adding 960' of additional piping. So elimination of the elbows alone would help that set up but 250HO difference is a lot.
Nice
crazy that the exhaust didnt need a wild set up.... it flowed 1850 hp,,,,
Love the content, would like to see a how to on boost and compression ratio's :)
Ok
Man i love the engine dyno work. Love where this is all going. Need to ditch that dynocom controller system on the hub dyno. Sending my love from New Zealand :D
Great info n video Steve
Would love to know my way around power like that
Always has me glued to what I'm watching
Just work n home life schedules won't let me get there yet
Been a passion for years though
Good video...need more on .the items on a turbo..best placement and brands names blow off valve to buy
16:50 is the reason why I (and probably your son) dont like carbs as much. With EFI you know so many more points of info and what exactly is going on. I have an efi mod motor and a carb 383 sbc.
Always so much information, advice, etc 👍👍
i love my turbo charged 383 . ive had it for 5 years now. nocarb though i have a ls1 ecu.
Watch the belt at 5:50 on the supercharger. It raises OFF the pulley because of belt flop. Hopefully Steve reads this and watches or noticed it when making the video. Maybe alter the belt routing some or lengthen it to move the belt under the pulley a little more hopefully to improve engagement. Plus that bottom side flop CAN NOT be good to a belt..
"Wadder to air" that's quite the Northern Midwest accent you've got, there 🤣
Wish I had the money to send my sbc to you for building. It would be a killer setup. ☺️😉😁😁
CSU was the best in my time + kev was a top person out to help .
Hi.
Thanks for the facilitation.
Legend!
Karl from Australia
Absolutely awesome setup old school small block Chevy making monstrous power what's the cubic inch on this piece
bucket list item #3 is to have a Steve Morris engine in my ssr #2 is to run said engine at Dragway 42 in Ohio #1 is to meet Steve, Cleetus + crew
Thanks for leaving the mistakes in the video…. Keeps it a little more relatable ✌🏽😎
I love this engine.
Very interesting and informative , as always. Many thanks.
Excellent engine, thanks for the video, all the best to yous and your loved ones
MY NEW FAVORITE CHANNEL BROTHER
Share to everyone 😁
love the video and also love all the info in here but Please for the LOVE OF RUM... lol turn the camera around when your talking so much please. It just makes it easier to understand your words and what your saying. :) hope u have a good day
I got my hands on a nice Barry grant carb. Its too big for my engine right now. but I cant wait till I can build by 445 olds
Nice K.I.S.S. build! 👌
I don't have an instagram account.
This guy is a legend! 👍🏻👍🏻
Thanks for the video hope everyone is having a blessed day
✝️🇺🇲🙏
That TINY A/A intercooler looks more like some OEM Factory POS than a high performance aftermarket item!
Interested in some general head specs. Mfg, 18° or 23° we have a 23° 434 nitrous motor that would be nice to shorten the stroke up in and throw some boost at it.
23 degree 245 runner track 1 heads
Blow thru is simple , it works and gives the engine what it wants , fuel injection tells an engine what it needs .
I'm slowly buying parts to build a 406sbc. I currently have, brand new AFR 210cc Competition Ported cylinder heads, Eagle 4340 crank, Eagle 4340 6 inch H beam rods with L19 rod bolts. Probably going do use a Dart SHP block. Could you recommend a good cam, intake, and carb? I want around 10.5:1 compression pumps gas 93 octane engine. It will be a street strip bracket raced car. Probably be 3000lb with a 4.10-4.56 rearend gear, glide or turbo transmission. I want to at least make 600 horsepower at the flywheel. Just need a good recommendation to go well with my cylinder heads. Heads are setup for solid lift roller camshaft up to .710 lift. Any suggestions would be greatly appreciated. Love the videos been watching a lot of yours lately.
Take care, be safe, and have fun regardless.
Would love to see a methanol no intercooler vs A2W setup.
3000 hp carb builds back in the day on this channel.. Steve knows a ton about carbs..
Can you break down all the different types of fuels??? Including meth alcohol ethanol and pump
I've always wondered how much HP the blower uses..Could you put a load cell on a seperate idler that increased wrap on driven pulley and then calculate power needed to run blower. Might make it easier to sort out blower losses or maybe a "good" blower
Hmmm, possible
They make blower dynos. Mostly used by people like top fuel/funny car to test blowers after a rebuild.
Wouldn’t be super hard since you can drive the blower with an electric motor. Measure how much power the motor takes to spin the blower a certain speed and you can figure out the power required.
Thanks for the wisdom
Fantastic video Steve!!
Curious what bore was this small block and what method was used to seal it up (head gaskets)…Copper/fuel hoops/O-rings/ MLS gasket? Thanks for the Great work and info!!
Dang. Thats rowdy for a smallblock!
A carburetor is a fancy fuel leak 🤪🤪😎😜
Putting in a chiller between the blower and intake. Went with the BB snout after rolling the crank keys.
Besides protecting the intercooler. Is it beneficial to blow off prior to the intercooler. I assume if there is less air mass going thru the intercooler than the deltaT can be faster? Have you see any numbers on this. They can be faster temp transfer on higher pressure gas/liquid.
Get your son to learn carbs, man! If the younger generation stops learning it, carbs will just disappear. And then the most raw, bare form of hot rods won't exist any longer.
My buddy 23 years old built a blow through carb 1987 turbo Toyota pickup. It doesn’t make a million horsepower. But from the 117 it used to make to over 250 it’s amazing in that tiny truck.
whaaahht!!! 1850 HP out of old school 400. Holy sheyitte
Big power small displacement bro!
Its impressive how all the high horsepower stuff if running a pro charger.
How longs that head gasket gonna last????? I’m sure SM cam make it last
I'm thinking about a turbo blowing through the sidedraft Webers on my Toyota 20r
Would love to see you work with SRC on the sbc they have in the trucks
Hey Amy chance you could share what brand power valve that is ?
Thanks for sharing the videos !
I had a Frankenstein on my coyote will built in coolers on both sides. I lost 300 whp over an air to air Intercooler. Not bad for a 7k dollar Intake that didn't work well.
When using a BBC crank snout, is this a n adapter that goes on the SBC crank, or are you using a crank that is custom built with a larger snout? ThanksJeff.
