Turbocharging My Honda 400ex (THE ULTIMATE QUAD) 

That would be nice

And he probably needs a bigger pilot screw since it sounds like it runs super lean to the point where it stops

Very good idea.

The position of the turbo matters. The best place for it is as close to the exhaust side of the engine as possible with the air intake on the turbo facing forward.

@@JumperXxXCables correct. However, there are companies that make turbo systems for corvettes that place them 4 ft from the motor. Sometimes the ideal set-up isn't the best set up for the application.

Agreed. The pressure boost is sometimes ducted a distance to a throttle body or the intake in the case of direct injection, but with carbureted turbo it's always practically sitting on motor's intake ports.

Acerbis made the plastic florescent color ones

wow soo funny nobody cares

@@busssintb5922 Your mom said to go clean your room.

@@busssintb5922 I thought it was funny nobody cares about your comment

They just don’t make enough power man. They are what they are. It’s an air cooled Honda. What makes 40 horse of your lucky 😂 turbos aren’t easy son. People don’t realize what u need to make a turbo work. 😂 u get all these Honda wankers. They wanna slap a turbo on from eBay for a couple bucks. Don’t realize that it really cost about 10k to put a turbo on. U need more than just a damn turbo. Especially on a bike. U need a bigger carb. Bigger jets. U need to completely redo every thing. There’s no way u can get that turbo close enough to the manifold. It’s a 2:1 exhaust. 😂. U could do it. But like the kid said. Never done it. It could work. With the right know how. I wouldn’t even do it. I mean your gonna get what your gonna get out of that. It’s meant for the gf to have fun on while u have fun on the race quad 😂 it’s really just so the girl can ride too 😂

@@checkforfleas9452 ebay turbo, intercooler, custom turbo header/s, and oil lines 😂 bout $500 for a turbo. unless you’re trying to push 800hp at 35psi you don’t need 10k to turbo anything… my v6 mustang is completely stock running 7psi on an ebay turbo at 240hp and it was less than $600 to do everything in my front yard …

@@checkforfleas9452 10k on a car is normal if you buy quality parts but he’s turboing a quad with cheap parts don’t that much money man

@@travisbellew7485 have u bump your head 😂 it’s wrong. Your pushing more air into the system. Therefor u need more gas to that mixture. The only one ways to get more gas is bigger injectors if u have them. Or bigger jets on a carb. If we are working with a carbed motor. Then yes. U can do that. But if your talking fuel injectors no way. Your crazy. In order to even make the fuel mixture right u will need an ecu and bigger injectors. Your air fuel ratio will be off. Not to mention the codes it’s going to throw. I know people love to hear back fires. That’s great. Sounds cool. But it’s wrong. That’s pure simple fact that the ratios are off. That ain’t good for the motor 😂 run a turbo for 600 bucks your crazy. Your one of those Honda wankers. Good go blow your shit up like the rest 😂 sure u can buy a turbo and pipping for 600 bucks that’s great. But how in the hell are u going to make it shoot more fuel to make up for that extra air? Duh a bigger injector and a tuneable ecu. Or if we’re talking older. Bigger jets. I know the kid is doing it cheap. It was just a damn statement. But even if we are talking older cars with carbs. I would never run a turbo. I would run a super charger. But u knew that 😂 your talking American muscle. It’s really only good for drag. U want speed. Buy a fucking Honda. Sure American cars can be fast too. But simple fact is. It has to be done right. Doesn’t only cost 600 bucks 😂 your crazy.

@@ryanyt2282 right. Just a statement 😂 I know what he’s trying to do. It can be done. He has to find that right mix. It’s cheap bc it is a carb. So I don’t need much of nothing. Just a pain in the ass. It would be real simple if it were injected. Probably should’ve noted that I was talking about a Honda car 😂 damn didn’t realize that. No it’s not 10k to do a bike. Sure. U could probably turbo that bike for a couple hundred bucks. I was just saying is it really worth it. That motor is great for it’s time. Yea it’s still great. But not like newer shit. Shit I have an 82 250r and I love that bike. Has a lot of power for what it is. But wouldn’t waste my time to put a turbo on it 😂 not for 7 psi lol and a headache 😂.

The issue is pressurizing the carb under boost with keeping it where it is. It wants air to be pulled through the carb not pushed through

😭😭

Gotta get it their first😅

😆😆😆👍

Wouldn't you want a tighter gap on the plug not wider? And a colder spark plug overall aswell

@@beereadyyy9849 Yes, run a tighter gap, around .035" and run 1 or 2 ranges colder plug.

@@beereadyyy9849 Yeah a tighter gap is needed under boost the spark doesn’t want to travel through the higher pressure air, if he used a larger gap it will likely blow the spark out under boost.

Yeah I figured that. I feel like the turbo needs to be above the intake as well so it can use gravity to feed the fuel.

@@2vintage maybe an electric fuel pump?

@@2vintage yeah, 100% man. Great work buddy, keep it up.

@@BandedG that pump would only help getting fuel to the carburetor, but im thinking of adding a fuel pump as well for that purpose.

I agree. Also it is not helping that the temperature is -15. You wont get very good gas evaporation.

I love those little blasters. You can make them rip with a little work. Best bang for the buck.

because when the intake valve opens the turbo has no energy to drive it. you need at LEAST 2 cylinders for turbo to even think about being viable. but really you wont find a factory turbo thats less than 3.

@@grenadegoboom4967 The turbo yfz450s that i have been around would beg to difer with you. They were faster than most anything on the dunes, but the fastest drag banshees

@@rogerthomas3798 LMAO. sure pal. funny story, im the guy that builds the chassis for those banshees that whip your ass. Ever heard of Tatum? You might be surprised who i actually am. This is my kids account.

@@grenadegoboom4967 I have a drag banshee as well (565cc twister). I have raced with some of the fastest guys in the country. I have never heard of you. I have not raced much in a few years though.

@@grenadegoboom4967 Why do people say this? Yeah single cylinder turbocharging isn’t ideal but it CAN be done and it works extremely well, but of course the more cylinders the better but to say that the turbo isn’t being driven during the intake stroke is silly, there is a thing called inertia and you have to realise the time between the valves being open is milliseconds it’s not as if the turbo spins and stops between exhaust pulses 😅

He definitely doesn’t need to go that route the boost pressure will not let the fuel naturally vacuum pull out of the carb as it would do normally

Yeah next video I change the setup on it.

apparently the timing marks are on the actual camshaft not the camshaft sprocket. I hope this helps!

Part 2 coming soon!

doesent matter wich way you make it...

@@miksu7784 that’s like saying it doesn’t matter which way a fan faces it would blow the same. It does matter and you that’s why all turbos are installed the same way.

@@stephendobson8905 havent you heard of a draw trough turbo setup before? you can make either drawtrough or an blowtrough. both will work..

@@miksu7784 of course but they suck and never run right, so I don't count them as the "correct" way to turbo a motor.

@@stephendobson8905 i own blowtrough car and it Works fine. Havnt owned an drawtrough so i have no experience in that. Only seen them online

Yep next video I will be doing that! Thanks!

how do rear turbo front engine systems work then, the only thing that should really happen with longer tubes is lag, raising the rpm when it finally kicks in. i think the problem is the carb going directly in the turbo, i've seen it work but its cringe. just leave the carb where it's suppose to be and make a tube from there to the cold side of the turbo, plus your restricting boost making it suck through the carb. you really want the tube to be the same basic size as the carb inlet/turbo out. plus you have to compensate for the boost pressure or your carb will not pull fuel when done that way the boost will push the fuel back into the bowl which is the reason for the turbo carb mount, its a cheap carb pressure work around and i myself hate it. you need a carb that runs off a fuel pump so you can have more fuel pressure than boost like with turbo road cars that have carbs, they usually double the pressure of what ever boost is being ran to equal it out. fuel atomization is trash too having it so far away, its just going to all recombine and bead on its way back down to the 2 foot tube lol

ever hear of rear mount

If he makes it a draw through system he will be able to use the carburetor but if he is going to send boost through the carb there has to be a plenum made before the carb or it’s just gonna push fuel back down the jets. I’ll be amazed if he is able to make it work in 5 videos but I hope he has better luck than I had cause it took a while to get it to work right when I done it and I thought It would be no problem, shit I have no idea how much time I had in it before I got it dialed in good

@@matthewjohnson2495 yea that stock carb wouldn't work sending boost directly into it, there are plenty of carbs that would probly work that use fuel pumps. as long as you can make more fuel pressure than your boost it should work fine. efi conversion would be better tho. it'll work the way he has it eventually. also the carb he's using is designed to be tilted up slightly and its tilted down it's probly messing with the float i's probly closed so its not getting fuel.

He would have to have a intercooler if he was going to try to keep the turbo as close to the cylinder as possible and there is not enough room to do either one on a 400EX. The oil tank sits right in front of the motor so putting it back where he has it is about his only choice and it will allow some of the heat to dissipate before it gets to the turbo as well. A hot charge won’t help the performance or the life of the motor or turbo

You could also add something in the intake going to the engine to better atomize the fuel

He explained why he wanted to try the draw through. Blow through may cause the floats to stick.

@@scottw2157 the floats won't stick they are there to control the fuel flow in to the carb for it to mix with the air. The float bowl is essential a mini sealed fuel tank. Fuel in the bowl will pass threw the jets to be atomised to mix with air that's why I suggested bigger jets to compensate for more air going in to the engine. Like I said only thing needed to go threw the turbo is air and exhaust.

Yeah that would be alot easier than using a carburetor

Thanks for watching!

You should upload a video of that sxs. I wanna see that. Going to sub just do i can see it hopefully

@@forzanoob I will do one day, life just got in the way of making RU-vid videos but I do appreciate the subscription! 🙏 Anyways the sxs is pretty interesting, it’s a Manco Deuce that I swapped a Yamaha XJ650 seca turbo engine into, it’s pretty mad really, it was a fun project, took me about a year to complete working on the weekends here or there, it’s deffo a one off 😀

This is exactly right. the vz21 is wayy to small..

@@KrustyQuad Right I reckon he could even run a K03 turbo just fine, that would probably be the best sized turbo 😅

That's not the problem. The problem is the turbo makes too much boost for that little motor and is not being regulated. The engine can only take in some much air on the intake stroke then has to wait for 3 more strokes before it can take more air...where do you think the boost is gonna go?? thru the carb and out the overflow lines. There should be no problems with running a stock carb on it. you don't need a special blow thru carb. Any carb would work obviously a bigger carb that flows more cfm would be better but he is still using a stock motor with stock head and stock valves that probably flows like shit. so its all wasted boost. just add a BOV regulated to 5psi max and all the problems go away...then you get to the fun part...Jetting and tuning lol
