I'm sure somebody has done it before. I was planning on stripping my TGB down to the frame and putting it back together just as a project this fall/winter and thought that maybe I should consider some mods. Has anyone here ever supercharged a GY6? Is it doable for someone with only limited access to a machine shop? What kind of parts would I be looking at to buy, if there even are superchargers for GY6 type engines? Would doing this be even remotely worthwhile and not cost a thousand dollars+?

I was under the impression that in order for something to be supercharged it must be fuel injected, I could be wrong. I would think a turbocharger would be easier because it would spool up and be connected to the exhaust manifold. A supercharger would have to be connected to something that spins like the flywheel or tire. I would love to see this done but would be costly. You would need a tiny turbo for the small ammount of exhaust gas the scooters produce. You could probably use any small supercharger as long as you modify the wastegate for a very small psi.

If you look on Ebay there are Electric Supechargers for Cars for about $50.
They draw about 3 amps, and can be set for on demand or full time running. The have an opening of 2.5 inch, so you would need to bring it down to fit the Carb. A muffler shop would be a good place to look for customing tubing.
I guess it could be done for under $100.

I was thinking about it again and you would need even more that I said. You would need intake piping for supercharger or turbocharger and an intercooler to keep the air cool that you are forcing into the engine. You would need to run oil lines, oil pump, and need an oil cooler for the turbo, it may or may not be necessary for the supercharger. You would need to lower the compression and get a forged piston to keep the cylinder from exploding. You would need a forged connecting rod or else the added pressure would snap it like a toothpick. A blowoff valve and wastegate to keep the engine from sucking in the air when its not supposed to. Some type of engine management system. Tons of fabrication, patience, and beer.

The trouble with a supercharger is that it has to be driven. On a car, its driven off the accessory belt, but seeing as how the scooter doesn't have this, you'd have a real problem turning the supercharger. Turbocharging is really the only option.
There are turbocharged scooters out there. A few guys have turbocharged their ruckuses. You can use a carburetor, but it has to be on the vacuum side. Personally, I don't think its all its cracked up to be.....its more of a novelty to get bragging rights.
If you wanna go faster, get a larger displacement scooter. You'll spend twice as much trying to get the 150 faster and it'll never be the same as a 250.

The 250 will give the most performance gain for the money.... and if that's not enough, then you can always try this: gokartsusa.com/turbokitroketajoynerbms800.aspxI should would like to hear from someone who has tried this on a scoot. 66 |
