does anyone know if anyone has put a super charger on a 3sgte or of anyone that makes one??

you know thinking about this, a supercharger and turbo on the same motor? On a four cylinder?

Say youve built this low compression motor that can handle crazy amounts of boost, and youve a big honkin turbo on there that needs a certain amount a exhaust flow before it even gets moving, then youve got a S/C that must spin many times faster than the engine in order to build boost at low RPMs.

At idle, youre engine will be fighting against a LOT of exhaust backpressure, no compression, and the drag of the supercharger. However, after you hit the gas youll prolly build boost VERY quickly, maybe too quickly. And unless you have some kinda clutch release system, youll have to deal with the parasitic loss thru the entire powerband.
It might be an effective sytem if you had a nice big V8, need good displacement.

Not trying to bash the idea, maybe use a small little centerfugal supercharger? Ive heard of electric superchargers, that might work.
