I'm aware of just about every product out there for the car. The supercharger setup for sell by revolution autoworks is a centrifigual setup, it puts out good numbers, but only one person is running it currently, and that's at 4.7ish psi. I don't understand how a blower will affect "driving ability", drivability will not be adversly affected. At part throttle and during the transition to full throttle the power delivery of a blower is smoother, more linear, and there for more easily controlled when compared to a turbo. The over all power potential is signifigantly lower than a turbo or centi set up but the change of the power curve makes for a good daily driven car with the goods to haul too. Plus I like to tinker and fabricate. I have no other reason to explain designing and building a "gokart" powered by a 33hp sixspeed motorcycle engine, sure I could have bought a shifter cart, but wheres the fun in that. (all I can hope is the fuckers who stole it crashed it because the brakes went out, if you know anyone with a bright yellow square tube frame kart (or someone who went to the hospital because of) with a 125cc two stroke suzuki motor on it let me know)

Please read:
This is a compairson between three types of blowers and a turbo set up, all dynoed, all on the same motor, and all at roughly the same PSI. Eventhough it's a ford v-8 it's very comprehensive none the less.
