OK, I want to add a few psi of boost to my go kart with a honda 5.5 horsepower engine.

Turbo is not an option since they dont make one small enough & I wouldn't have the oil supply to lubercate it anyways, Supercharger, ummmm noo, So here is what I am thinking...

Maybe taking a leaf blower apart & mounting it to the frame & using a belt to drive it from the rear axle, Would this work? I have no idea, Another thing I was thinking about, Would a smog pump off of a car work, I read somewhere online that they can make 4-5 psi, I have no idea though???

I want to keep it cheap & just want to make it a little faster while having some fun at doing it. Any ideas?

The engine is factory with the exception of a header pipe that I made for it, Right now it goes somewhere around 40 MPH with my 250lb azz on it. That is with me reaching back & holding the governer linkage, LOL. Anyone know how to disable the governer all together on a honda 5.5 engine?

Thanks guys!

I remember a joke video about a leafblower acting as forced induction and I think it was a joke, so I'll have to say no. You can probably rig up a nitrous kit small enough though.

you can't blow through a carb without encasing it so equal pressure is everywhere. a carb setup usually is drawn through the carb and into the compressor(turbo/supercharger). you might try to find somewhere that sells nitro for drag racing and add it to the fuel, or nitrous(which would need an enrichment circuit for fuel) so, cheap? probably not. easiest way would be to find a larger hp motor and bolt it in.

Nitro for drag racing? If I can get a hold of some would it hurt the engine you think? What percentage? Maybe 75% fuel to 25% nitro ???

Why can't you have a blow through set up? I have seen this done with a 83 mustang GT, he used 2 IHI turbos & had them routed directly into the top of the carburetor. Would this not work on a small engine? Just currious.

Thanks.
 
My friend and I took an old Tecumseh and put it on a go kart frame like that. We took the torque converter off all together and did straight chain drive. We had to jump on the cart as soon as we started it or it'd drive away though at idle without us on it. That'd definentely make it faster but you would also have to find the right sprocket combination depending on whether you want top end or bottem end. Or you can find a different torque converter somewhere. Taking the governor off can't be that hard. I don't know what it's like on yours though.

One thing that might work, we put gas meant for a two stroke dirtbike...mixed gas in it and at night after taking the spark arrestor off the exhaust would have a small flame that looked like a butane lighter come out of it.
 
Cool guys, Thanks for the ideas. I just thought it might be kinda neat to rig something up to give it a little bit more get up & go. Back in the day we always just found an old B&S side shaft engine & took the govener off. This Honda has some weird looking linkage though.

I am going to try to find a pic of that mustang blow through turbo set up if I can.
 
Can you run a bigger jet and alcohol? That what all my friends do on their sleds, quads, and bikes.
