More Power

[DEATH_INC.]

Somewhere round here I got an old CM400 twin that I hung a turbo on a while back.....works ok.One of the TL boys on Gixxer.com was turboing his TLr but I never caught the end of it so I don't really know how it turned out.
Turbo's are great,but they too have limitations (like superchargers),you can reduce spool up to almost nothing,but the turbo will be quite small and will run outta puff up top.Don't get spool up time and lag confused with each other,as they are quite different.There's plenty of turbo's out there to run on a bike,a t2 will work on anything down to a 500 4.The CM has one of the turbo's off a twin turbo legacy on it.
There's a lot of myths about turbo's and superchargers,they really aren't that tricky.

I have never seen one small enough to fit onto a minimoto, I had a thought that a small electric blower may be the go for a minimoto.

An electric ducted fan off an Rc plane may do the trick, run it off a microswitch at a certain throttle position, for a power source use lithium polymer batteries... , may need some sort of rising rate fuel regulator also, my mate has three daytona minmotos (hes gonna start to race soon) i might just have a word to him about doing something to that description

Ummmm.......no.You won't get any boost from it.Those electric superchargers don't work either.It's a load of shite.Think about how much power it would take to compress the air quick enough to pump more pressurised air than your engine needs.

Bah, I turbo'd an old 4 stroke scooter with a short length of flexible hose, and a 12 volt hair dryer once, just cut the heating colis in the hair dryer, and force fed the airbox/filter.

Dad was not impressed, but I enjoyed it.

We talking for a Mini Moto, I thought it would of worked.. the Ducted fan im thinking of with a brushless motor (50,000 rpm), manages to generate enough thrust to fly a 5lb RC plane , the fan is about 90mm, the brushless can reach its top rpm in 10 rotations.

an example of how kick ass brushless motors are - its a boat i know, but its brushless powered boat doing 200kmh - its the world record holder at present

Reckon one would be small enough for a minimoto or at least a little commuter bike? I want to get something small and cheap to modify so if I ruin it/blow it up it isn't so much of a problem as if I tried modifying the CBR

Don't the 110cc pit bikes (ThumpStar) have a battery driven supercharger option?

Just had another thought.............. smoke came out of my ideas after this

could use a Model Rotary O.S Engine (normally runs on glow fuel), rotary as a supercharger

Personally, I'd use one of the turbo's off a Mitsubishi Legnum VR4, a MHI TD03, assuming you de-compressed the engine to about 9:1 at about 14psi on a litre bike you'd be seeing about 200whp with a nice quick spool up.
