I don't think some people realize but these carburetors don't even have an accelerator pump so you have to have the engine running drawing it through the carburetor with the vacuum of the engine. So cracking the throttle a couple times doesnt prime anything..

[Pro.]

Go to a draw through setup carburetor with a smaller turbo and put a 4 inch by 4 inch tube to increse plenum volume before it goes into the head and the boost numbers with be more consistant. The way your carb is setup now (blowthrough) its pressurizing the bowl which makes it run like crap lean.. only way around it is a 1to1 boost reference fuel pressure regulator or just go to draw through.

1st pull, you could see & hear the boost hit lol. I bet if you put a smaller turbo on, you would get more boost. Makes me wanna turbo my scoot build 🤔🤣

I built a mini dragster. The frame is a small go kart sized top fuel dragster looking chassis about 2 feet shorter then a jr dragster. It has a 212 cc predator engine thats bored and stroked out to a 230 cc with a small ebay turbo. It runs the 1/8 mile in 7.5 seconds and that was the first time out and not turned up all the way either the second time out i got it down to 7.168 at 102 mph. is its fastest pass ever so far and that it turned all the way up and it's a beast. Ny goal is to get it down to mid 6s but doubt it and its got some torque to it throws you ibto the back of the seat hard when it launches. I have race asphalt and dirt oval full sozed racecars that make 500-800 hp in different classes but this little dragster i built is alpt of fun to drive and makes a great braket racing car i placed second in the first ever elimination bracket race ot ever entered on the 1/8 mile

How did you get it to work with a carb, I thought it would over pressure the bowl

[kylesyx]

So you ever had the turbo take flight on you?
Looks a little big for a predator 212

[vgair]

add a pulley for a small power steering pump and used that to oil the turbo

[travisjohnson]

I just bought a garrett gbc14-200 to put on a 5hp flathead briggs and stratton

[Mason-qm]

I just started my build how did you get the turbo to work qith the carb i cant get mine to idle just right i think it just overpressureing the carb

[alohabobbylaguna]

you keep it very simple any body could do this AKA KISS KEEP IT SIMPLE STUPID this is a old school slang at it very best one day i plan to do this to my Honda GX 340 FOR MY Manco go kart Thank you for sharing this

I assume that is a single cylinder 4 stroke ? If so, it requires an air capacitor when a turbo is added. Basically, some type of pressure vessel 4 to 5 times the displacement of the engine in order to store the charged air (cause you only have one cylinder). This is placed on the turbo pressure side prior to anything else including an inter-cooler. source MIT turbo single cylinder small engine research 2014, analogy, think of trying to spray paint a car with an air compressor that has no tank on it. you would need a huge compressor, and you dont have that option when your power source for the compressor is a tiny engine, so you need the air tank.

When you said barstool racer that’s not what my mind went to

[finneganfun]

What is the pulse pump for? And the little blue line?

[elisomarcastro]

Motor 420cc 4000rpm, qual turbina coloco nele ?

[poker]

Turbo prolly too big to do anything in that little engine.
