If I had a 4-stroke I'd definitely be playing with forced induction.
Doesn't really work with 2-strokes though. |

There isn't a need to go turbo with these motors. In their stock fashion, you would grenade one quicker than you could say "aww crap". You can't put a band-aid on a turd, but this turd can be polished...
You can take one of these motors and machine them to make gobs more power.
With the right machined head cap, trued surfaces, proper porting and crank balancing, with a tuned exhaust, I bet you could squeeze out 5-7hp. The biggest improvement you can make to these motors is crank balancing. they are so unbelieveably out of balance from the factories. This is why they vibrate to oblivion. That probably robs at least a horse and a half right there. A better carburetor wouldn't hurt either.

Unfortunately this makes for an extremely peaky motor. One that isn't well suited to riding in the city.
Works great on the salt flats tho.
A hair dryer is not going to work. It moves air around well but it won't create any pressure. People have played around with this before using computer fans. If you search some you will find out what they discovered from their experiments. |

| | Re: Home Brew Hair Dryer turbo. Thanks guys. I just recently dissasembled the hair dryer and found the blades on the fan were some cheapo plastic. Not to mention hair dryers for safety reasons are not intended to be able to build up any preasure. Probably my next project will be figuring out a way to hack my air box to scoop air in/ Add NOS/ HHO/ water injection? lol i can imagine that baby granading between my legs and the 00dles of razer sharp shrapnel violating where the sun dont shine.
Better yet maybe the safer option would just do the scoop/ram idea and add a nice boost bottle!
here is the url Boost Bottle Industries They also offer a cool N2O kit at Nitrous kits
I found this stuff looking into another rather dangerously stupid sport called motorized street luge. Powered Streetluge

I found this stuff looking into another rather dangerously stupid sport called motorized street luge. Powered Streetluge | Regarding the HHO aka Brown's gas. I would have serious doubts as to whether it'd work on a two stroke engine, considering that you gotta mix oil and fuel, not to mention the current you'd have to send to it so electrolosis can take place. You could probably hook up a battery to it to get it to do that. I was thinking of doing this too just to see if what supporters of HHO say are correct, factor in that these bikes get rediculous milage anyway and you could seemingly go forever. Once again, if you can find a four stroke motor to do this to, I'd think you'd have better luck. | | Thread Tools | | | | Display Modes | Linear Mode |
