Turbo Go Kart Finally Makes Boost!

In this video we put a Turbo on the 60's go kart! What we needed to do was make a turbo manifold, oil system, and electrical system to make sure the turbo could run completely autonomously, that way when we hook it up to the engine, we would know that there were no issues on the turbo side of things. After we did that we ran this turbo kart under boost with 2 carburetors, made custom intake piping, and finally revved it up and tuned it so it ripped!

Before we began the install we filmed some awesome driving footage to get a preliminary test so we could compare before and after the turbo was installed.

Thanks for watching and be sure to stay tuned for this thing making some boost while driving!

I would personally just do a pull through system turbo boost outlet directly to the intake and only run one carb

[Spadedlife]

I am glad to see kids still messing around with shit like this give them a big thumbs up good job

[benhawke]

When you place the carb after the turbo, it blows the fuel back into the the float bowl and can blow the seals of the carb and fuel out of the float overflow. If you're going to keep the 2 carb set-up, then run the the pre-turbo carb wide open all the time and use the second carb as the throttle control or vice versa. Also on the idle carb on the boost side, you should block off the float over flow and any non-jetted ports leading to the float bowl. But I recommend getting rid of the second carb on the boost side and getting a lectron carb and placing it on the intake side of the turbo. Lectron carbs are self tuning and work amazingly for carb turbo setups.

Try using one carb at the intake of the turbo then at the exit use a continuous pipe to the in take of the engine

Do it with just the draw through. No blow through.

Y'all are making this build far more complicated than need be. Put the Mikuni directly onto the turbo air inlet. Connect the boost side directly to the engines intake. Plumb exhaust and jet up as needed. So long as the turbo draws air through the carb instead of forcing air/pushing air through it you'll be fine.

[treykilgoreiscool]

You can always divert boost pressure to the gas tank and keep the whole fuel system pressurized, that would keep the carb able to pull fuel through

[henryaurand]

The blow through carb will need a high pressure fuel supply if you want to do it that way. What happens is the bowl gets pressured by the intake air as soon as you make any boost and it pushes all the fuel out of the carb. Some people actually put a sealed box around the entire carb to help with help solve pressure differential issues.

That being said, you should be able to make it work with just one carb up-stream of the turbo (draw through). With a properly sized and jetted carb you should be able to make it run well. I did this on a car of mine and it worked pretty well.

Just use one carb ! keep the mikuni as a blow through keep that screw in the vent and run a boost reference line to the venturi then install a pulse fuel pump job done ! 👍🏻

*Build Break Repeat* Awesome project and video, following your progress for sure. An idea for a future video: Put a 1980's VW smog pump on a predator as a supercharger. I have seen some examples that make crazy RPM's and power. It is essentially a scroll supercharger with the perfect plumbing dimensions for a small engine. Thank you for all your great content, longtime subscriber.

[drewalsup]

You guys are the first people to do this and have any signs of it actually working. I think cars and cameras tried this and grind hard plumbing co tried this and neither of them had any success, good work engineers lol

[miguelamaya]

We saw your invention but, couldn't put heads or tails on it. We installed a Hayabusa engine on a cool off-road go-cart and came up with an Awesome built. We have a 10-gallon gas tank on it. And we are very proud of ours. .gas lasts forever.

[leespeed]

I love how everyone tried to help here and not be negative to these guys, this is how its suppose to be. I even learned some things thanks

[askbeforeplaying]

I wanted to turbocharge a go kart, but now I want to turbocharge a rotary go kart. This one video has made me subscribe.

[Cumminslife]

Your original blow through setup would work fine if you just route the carburetor vents to the compressor outlet. Also will need to enlarge jets otherwise it will run far to lean on boost. Watch my turbo welder video for more info.

[wirewrks]

I had several experiences turbocharging carbureted small blocks back in the '80s, and I'm still turbocharging vehicles today. I highly suggest using a "draw thru" (or "wet charge") setup, over the "blow thru" (or "dry charge") setup. A single carb on the inlet side of the turbo, with a discharge pipe into the intake ("draw thru") is less complicated, and makes for easier tuning. A "blow thru" setup requires fabricating a totally sealed enclosure for the carb, so the carb's vent circuits "see" the same atmospheric pressure from the discharge pipe, that the venturi, idle circuit, air bleeds, fuel bowl and the needle/seat all "see" when under boost. Deleting the turbo outlet exhaust housing, in favor of the integral wastegate delete and wastegate puck block-off plate, will obviously cause high boost pressures. But, if you can keep it around 5-7 psi, while using the stock carb and increasing just the main jet 10-15%, you'll probably be in the ballpark for fuel requirements. BUT... after seeing the surging, low pressure and air pockets in the oil supply for the turbo, these recommendations may just be moot points. Anyway, good luck with the project. Happy Trails..!!

Single cylinder carberated turbo running clean. I dont know if thats a first but its the first ive seen it work. Good job guys. I hope you get this runnin smooth. That'd be pretty cool and not a bad claim to fame for your channel.

[Vr.christos]

I think you guys should make a Diesel kart

[GMC]

I did the same thing, but I’m running a mikuni with the bolt threaded in. I had the exact same issue. All you need is a pulse pump. Cost 15$ and solved all my problems, just make sure you put a t in the line that returns to the tank so you don’t flood the carb

[michaelkalt]

Eliminate the blow through carb. Put a "Y" pipe on the inlet side of the turbo. Put a carb on each side of the "Y". Then you can have one for idle and make it so the second carb comes in at 1/4 throttle or so. Kind of like a Dual Quad setup or a Mopar "6 Pack" set up. It is referred as progressive linkage. Blow through carbs don't work unless specifically built as blow through.
