I have looked into a supercharger several times but keep chickening out cause of the unknowns, I guess the biggest thing is has anybody had one for a some time, I meen how do they hold up, would they be at least as good as a good brand turbo? knowing whatg I do about turbos and blowers, if a blower set was right, and the price could get even close to competitive I thing you would see a lot more of them
