Superchargers aren't really made for our types of cars. Also superchargers take horsepower to create horsepower as they are driven by a pulley. A turbo is essentially free power since it uses your waste gases to power itself. There are 2 types of Superchargers out there.......Centrifugal and Rootes. The rootes ones IMO kinda suck as their top end really blows ass. Centrifugal ones actually sorta have lag like a turbo and do better on top, but still aren't as badass on the top end as a turbo. There are many forms of turbos as well. You have different trims like P,Q,R,S and shafts like thrust, BB, DBB.......and antisurge housing........the possibilities are endless.......
