rotrex supercharger

[Vanderkitten]

Your supercharger will rob more MPG from your motor than a turbo, and there is no way around it. It adds mechanical drag to you motor whether you're on the boost or not. You lose some rev-speed as well (my non-mechanical term for how fast your motor revs).

The Supercharger tends to be easier on the motors since the boost occurs at lower RPMS, and Turbo spools up later meaning you spend more time in high-revs and detonation is more likely.

IMHO, Superchargers are great for low-revving motors where a Turbo would not spool up and provide adequate advantage or heavy vehicles like any Mercedes or a truck.

I am not sure why the mini cooper S has a supercharger... seems like the wrong move to me... sign me up for the turbo!! After having one in my Jetta GLI 1.8T I'd do it again... but I can see the desire for quick lane changes and possilby autoX being smart applications for the SC.

Turbo v. SC... Shoot it out!! I'd pay to see that!
