yeah.

Plenty of people SC euro's. Plenty go turbo too. But if you were going to go all motor on say your M3, you would be looking at huge amounts of money to make more power out of an engine that is already fine tuned close to perfection. Look at Vw's, vortec S/C's are all over vr6's. There are plenty of audi 2.8's with the PES S/C system on it. And for bmws there are a shit load of companies that make them; Dinan($), RMS, ESS, Sebring, Vortec, etc. Heck, i even met a guy with a supercharged M5 last week.
