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!

@ENZEEVIDS 5 жыл бұрын

the problem with that set up is the fuel droplets, instead of remaining atomized and gas like, all the way to the combustion chamber, condense on any of the surfaces that it flows over so in the end you end up with a mixture that is no longer stoichiometric. obviously the longer the intake tract the more surface area there is to cause problems.

@ROTAXD 5 жыл бұрын

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.

@benhawke7231 5 жыл бұрын

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.

@treykilgoreiscool 2 ай бұрын

@CygnusHomes the safety concern is that the blow off valve may release pressurized fuel air mix (boom). You have to be really careful. The best option I can think of is having a longer boost tube than plenum to allow the expansion of the fuel air mix. You also might want to put a spark arrestor on both sides of the turbo to prevent ignition of the boost tube in the event of air fuel reaching the hot compressor

@henryaurand7951 5 жыл бұрын

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.

@thegenerousdegenerate9395 5 жыл бұрын

Couldnt they just run a boost line to the tank and seal the lid tight?

@danmackintosh6325 5 жыл бұрын

That would work actually, I did think for a moment that the sealed tank would draw vacuum as the fuel got used up but it wouldn't do... Mounting the carb in a plenum is an idea I've been pushing since the first turbo vid too, solves so many problems instantly.

@danmackintosh6325 5 жыл бұрын

I don't know that it would be any more or less dangerous than having fuel pressurised by a pump though really. In an enclosed space like a fuel tank the vapour/air ratio is much too high for it to be explosive, hence why it's possible to use electrical level senders and in-tank pumps without danger of explosion. I guess if the boost pressure caused the tank to rupture and spray fuel everywhere, but I don't think it's overly likely with the levels of boost this engine will run. Like you say though, a plenum and properly regulated fuel supply is the better option & what I'd go for if I could.

It will keep your engine nice and safe under boost and then lean it out for maximum power. Maybe even get a cheap wideband o2 with a gauge to monitor the air/fuel ratio.

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.

A calculated and correctly tuned exhaust will give maximum spool and an optimum powerband in a required rpm range. I tested several turbo back systems on my car when struggling with a restriction problem and a 2.75" milltek out spooled a 3" milltek by 300rpm on the same afternoon on the same Dyno. It dropped around 8hp to the larger diameter. The 2.75" was resonated, the 3" was not.

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..!!

Hi there, u guys r cool, were do u get the small tubing for the charge pipe?

I recommend sealing the fuel take and adding a fuel reference line to the take and only using one carb the one with boost.you need to add 6.8% more fuel per psi and since the carb you are using does not use pressure 1 psi is 6.8% more fuel.when there is no boost there will be the same amount of fuel as normal and it will use the boost referenced line as a breather.

hi, how was the carburetion set up for the 2 carburettors?

I agree that you only need a draw through carburetor and jet it a little higher for better fuel distribution.

From the way the left wheel shakes around when you run the engine makes me think that the axle might be bent. Best of luck :)

Can’t you run turbo pre- carb by making a port for the turbo between carb and block ?

Is the fuel coming in before the turbo?? Fuel going across impeller???

You could have just used a mechanical FMU that activates by boost pressure. The more boost pressure you have, the more fuel it allows. Cool project for sure!

Draw threw turbo setup is the way to this to operate, put ur carb on the turbo intake and remove the carb on the engine, run ur charge pipe from the turbo straight in to the head port ,sorted boys ,😉

Guys have u tried with a double or partial intake? One on the na carburator and a switcher or something Like a vastegate when the pressure of the air overflows it engage the turbo

How are you welding stainless with a MIG welder? Special wire? Those welds don't look too bad, what is it?

Just a couple of kids trying to figure out how to make something work. Kudos to them. Instead of people criticizing their work they should give them tips to make it better
