I’ve been looking for a video that SIMPLY and slowly explains how boosting with a carburetor works and why!!! Thank you so much everything makes sense now!!
Seriously same here and this id exactly it
This little "series" about turbo-ing a bike is honestly one of the best explanations of turbos (car or bike) and how they work that I've ever seen. I really hope you follow this up with more videos explaining some of the other things you discussed previously.
Keep up the good work!
I'd have to agree with you as well he really does do an excellent job.
I'd love to get him to do a video on twin charging as he explains things well and precise but without dragging on like I do. It'd make alot more people realize it's not as hard as it seems on cars.
My bike already has a fuel pump. Now all I need to do is duct tape a turbo on and I'll basically have an H2 right?
Duh wernt you paying attention
i love that you put golem in the thumbnail it looks so funny!
Finally someone did a simple explanation. Thank you
You are too smart
Hey!
About that with 15 psi fuel tank pressure 20 psi turbo pressure is not a problem to solve. You put on a gas pump, gas pressure gauge and a gas pressure regulator, and for make sure that the bike does not goes lean, you adjust the fuelpressure 2.9 psi higher than the turbo pressure👍🏼 I do that on my Honda CBR900rr turbo dragbike, and it works perfectly😁
How do you match air pressure and fuel pressure? Its not always the same to fix it at some value with pressure regulator.
Excellent explanation of the issues when turbocharging. Kawasaki did the blow through carb thing in 1979, but the 84-85 DFI fixed all the issues.
Watched.
Despite my unbridled hate for green motorcycles, supercharging is the way for 2 wheels
Delivering the goods man! I currently run a drawthrough setup on a Suzuki Savage 650 one-cylinder. Started it up a few days ago and it ran very well for what it was, idle aswell as gas was no problem. i figured there would be problems with fuel delivery since the fuel has to travel for about one meter in pipes after the carburator. But, as said, no problems.
Well, draw-through seemed lika a more simple setup for me at the time. Maybe i will rebuild it to a blowthrough later, but i want to test this out first. I will probably have to re-jet to bigger sizes though, i have not wind it out on high rpm's because it's snowy were i live.
Do you have any pics of this set up?
Defiantly learned some new things in this video. One thing i think you forgot about is explaining the air screw passage and pilot jet.
Wow, thnk you for this video:)
That was the best explanation I've heard yet. Thank you.. simple to the point. I'm contemplating putting one on my 87 Suzuki savage. Single piston 652cc. Any advice?
Shout out to tutor👍 and thanks to youtube algorithm 😎😎💣
I turbocharged a kawasaki 220 bayou with a turbo off a 300d turbo diesel. It could spool it but the draw through pipe we had couldnt handle the vacuum and would snuff the bike out.
Haven't even watched yet!!! Matt your fucking awesome
Your writing is better upside down :D
Does the restrictor in carb vent pipeline help when you suddenly close the throttle (before blow-off drops the pressure) to prevent the engine from overfilling with the gasoline?
Yes - more on this when I put together a demo
i love this series mate. not that i have a bike but is sure is great watching this! (offtopic. in your update you said that isac would maybie continue tairing down the crap engine, did he? )
Not yet - he was busy this weekend
Oh well, to bad. keep up the great work!
Makes sense indeed, it kind of reminds me of how I've had to tune my car after a turbo conversion, the ecu has no boost sensors so we basically configure the engine to cope like 20psi (5psi boost) is the normal pressure
Ermmm can't do an S backwards... (3:29) after writing 5 or so before..😂 Great video matt.. As always.
@ 6:06 SNAIL!! lol omg that made me laugh so hard this video definitely made my night thanks Matt!
just cut poor oul ave short when i saw this notification.
exelent video thanks mate!
great vid
You´re forgetting an importing thing, the pressure you put to float bowl often needs to be pressurized with dynamic pressure.
To solve this you need to take pressure to bowl with a pitot tube.
boost reference to the carbs would be better through a pitot tube system from the plenum wouldn't it? Also you'll want a rising rate fuel pressure regulator so the fuel pressure stays 2-3 psi above the absolute pressure in the venturi :)
Is it useful if i turbocharge my r15v3..? 155.1cc motorcycle
What about doing a similar set up like say a dodge cummins where the turbo is put on the exhaust. And doesn't goes through carb or injectors?
Cant you just put the whole carb in a space and pipe the turbo into it so the pressures are balanced in the carb? Like a pre-manifold, manifold...
NM see MadxJim comment below.
This may be a stupid question, but how do you prevent the fuel pump from overfilling the carb if sitting at idle? Is the pump flow rate regulated by rpm or some other method?
The pump has a bypass circuit where the pressure for the fuel circuit has a threshold to overcome. This can be in the form of a minimum level and a check valve.
@@dirtygarageguy lol muuuuuch simpler than i was thinking. Thanks for the quick reply
@@dirtygarageguy I'm going to run an after market electric fuel pump with a boost referenced fuel regulator with a 1:1 ratio. I'll set the fuel pressure at 2-3 psi the regulator has a boost reference port/inlet that I'll connect a hose to which connects to the back of the plenum. Then no matter how much boost pressure you have the fuel pressure will always be 2-3 psi above my boost pressure and I'll have a return line ran back to my tank. Anyone doing this with a carb'd bike knows we don't have an ecu. So unless you own a Dyno or at least have easy access to one which I do not they can do like me and install a wideband AFR unit. Installing the wideband will cut out a lot of headaches when tuning
Being honest my knowledge comes from a very patient retired engineer that I was blessed with meeting two years ago.
My hat comes off to people like you and him that are willing to share the knowledge y'all have. Thank you
So you wanna Turbo your bike: Dude, for the video serieseses would you mind naming them something like "Part 5 of 5" Or "Part 5 Final" Just something so we know the series is finished. Cheers !
LOL when is anything finished?
USD forks have nout on your upside down 'art work' !
Guy Martin did this on his bike but it was not really ready if anyone remembers it ?
Great informative videos! What do you think about putting a turbo on a 1994 CBR250RR inline 4
Something i wonder about is why did they invent the carburetor in the first place , the functioning of a mechanical ijection sistem semes more easi to comprehend in my mind . But who am i to judge the experts ?
im currently doing a pull through turbo at 7 psi on a 171cc forged internal gy6 motor. im using a oko 28mm carb, ive got a wideband and i can tune the jets accordingly. but my question is should i be okay with a vacuum fuel pump getting vacuum in between the carb and the turbo air inlet? going for a land speed record with this motor and your advice has cleared up a few things, but id love a video on the pull through style
"going for a land speed record"
- with a GY6? Are you actually insane? Secondly what turbo are you using?
The Workshop vz21 and the record is only 68.
So basically a kit built to work at sea level won't work at 5k above sea level ? Even if you buy a fully set up kit you will have to alter it for a carb bike. Re jet and tune ,blow up motor after motor until you get a base line tune for weather conditions.
You will have to tune if you want it to run at its best, but it won´t blow up for simply having a "not optimal" air-fuel mixture.
Why not just pressurize the tank the same way you pressurize the float bowl?
That doesn't sound like a good idea...
The only blow through setup i have seen was on a Renault 5 GT Turbo, are there benefits of blow through vs pull through and visa versa?
MadxJim A raider you say? Were those the dark blue ones, or am I getting them mixed up with the Clio Williams? :p
We'll get to this in a future vid
MadxJim must be rare indeed, I've never seen one in the wild
can you make a video about how to re-set the ecu and what kind of a program i need to put on may laptop Because i have no clue how to do that I beg you
Didn’t know you were me squiggle
You related to Tony hart?
mate can you show to us in ACTUAL how to install properly the BLOW THROUGH AND DRAW THROUGH SNAIL CHARGING?and then EXPLAIN it again
That was all redundant Matt. Delboy has already shown us how to do this shit. Apparently all you have to do is what he does: eat beans for breakfast, stick one pipe up his arse and link it up tho the one that catches the crap coming out of his mouth. Obviously the other end goes into the vent on his fuel tank and increases the overall fuel pressure. It's really very simple. And all your wittering on about blowback is totally unfounded. He's not at all concerned... so why should we be?;))
Very interesting. The cool thing is, I actually put an brushless edf (electric impeller) on a small 4 stroke engine (way too small to produce any boost, but.. learning!:)
..and even with that small edf I discovered the problem by myself. The engine stalled as soon as I powered up the impeller. And fuel came out the vent tube I think (if that makes any sense, maybe the vent was below the fuel level in that carb). Anyway, I had the genius idea to connect the pipe right after the edf to the overflow/vent of the carb, and it worked just fine hehe:)
but didn't produce any power cause 400w of electric power is nothing.
Anyway, even if you have figured everything out, I have a question: Would you need a bigger jet? I'm obviously moving more air (by mass) through the carb at roughly the same speed as before (so I need more fuel to burn). The pressure difference on the fuel jet is the same as before. But bernoullis principle says that the pressure drop is proportional to the density of the air, which is higher at the higher pressure. ... this would mean the same jet would still mostly work.. ? yes no maybe?
"I have a question: Would you need a bigger jet?"
- yes, as air density (number of oxygen atoms) increases then more fuel is required - this is where the extra 'power' comes from.
this might get a mention in a later video, Matt goes through things in kinda "baby steps" so that people can keep up, instead of everything at once and people getting confused and lost off or simply losing interest
is the increase in air density not enough to pull in more fuel?
Air pressure drop and the gradient of this drop is what draws fuel in.
really must remember to refresh the page before commenting on something!
what about a dual carb system?
What about it?
would it help with the flow or something?
are you meaning having one carb that's turbo'd, and one that isn't?
maybe
Turbo a Suzuki gz250? Realistically what am I looking at if I throw it together. I want boost with some power, the sounds and a little bit of pull, and if not what bike would you recommend to Turbo?. I really am interested in doing a bike, just need some guidence.
-Nick
"what bike would you recommend to Turbo?"
- I don't. It's a personal choice. Do you want more power from your bike or you just wanna turbo something?
The Workshop I really just want to turbo something, I would like to turbo an older carborated bike but I'm not sure where to start
Square spark plug in a round hole.Seems Legit. 😃 lets talk about a car tire on bikes again. Its worse than arguing about religion
well tinfoil hat, let me ask you another question. what could possibly go wrong?
This is all assuming there's no intercooler used right?
Not many people use intercoolers with bikes
MADEinTexaz as the fuel goes from liquid to vapor it cools the intake charge
First
Sad ass song in the intro
I stopped at 1:06, and who the fuck would use a carb and turbo the bike??? Sorry the 80's are over. FUEL INJEKTION IS INVENTED! Matt don't make our life harder then it is. Just say: To turbo a bike with carb is possible but bullshit if you can go fuel injection you get the best result and most power out of it. Well and todays bikes that you might consider to turbo are fuel injected anyways.
i would disagree, i would not turbo a bike i ¨care about¨ for the simple reason that it would just not be reliable enough. so maybie trying to turbo an older bike that is cheap is a better idea. but that is just my opinion. plus i do not know how an IFE system would react to a turbo setup. since the preasure is not constant enough. you would propably have to get special software on your ECU. and i would think that is hard to come by for a bike.
Jesse, So you rather turbo carb 1970's 80's bike then an fuel injected 2000' 10' bike that has fuel injection? I would turbo my 2007 K1200R BMW if it would make sense to get more out of it but with less then 3sec form 0-60mph all I get is more wheel spin. So to turbo a small engine bike makes more sense. Fuel injection on bikes starts to be more common in the 90's. And a stand alone unit to control ignition and injection is cheap and easy done by picking timing up at the old ignition. Add a sensor for pressure and emission and all you need is a throttle body with the intake fuel Injektion and a few bits like fuel pump and it is done! easy and save for the engine not to lean out.
I guess i learn evry day. thanks for the info.
Jesse, you will dump all engine management and install a standalone ECU and that manages all you need. And then you tune it to that what you have installed and the power you ask from it. Ok the fuel pressure will have his own pressure regulation... And no matter what engine you take it will have less life as more power you ask from it... That is one reason for the old saying cubic capacity is only replaceable by more cubic capacity.
what i meant to say about reliability was more about not screwing with your day to day driver, not that old bikes are more reliable.
Yor're not doing a good job mate explaining :)
