Hi
I have been looking up on one of those electric superchargers .

http://www.force-flow.com/ff_warranty.htm

I have spoken to one of the reps and they run on a brushed motor and would only be good for 20 seconds max before you have to go off the gas to let the electric motor cool down .

The motors only rev. at 20000-30000 rpm .

I was thinking of using a brushless motor to gain a higher rpm and psi .

I was told by the rep that it would work .
