Im doing a blow through supercharger, so can mount the unit anywhere, either side of the engine, so the extractors wont get in the way. Have driven loads of turbos, but to enjoy them u usually end up doing 120km/hr in a 60 zone. Also a supercharger is more fuel efficient - depending on how u drive it, which in my case means it wont be more fuel efficient. Other than that, everyone does turbo. Have driven a few supercharged holdens, and for everyday driving (read not on a race track) you can feel the power and enjoy it even at low revs(not using a centrifugul turbo style blower).
Cheers.
