btw i dont remember where i saw it, i think in a magazine but anyway i saw an electric supercharger that could actaully work. the body of it was not a plastic tube like the s**t on ebay it was a supercharger free of pullys basicly. problem is it was powerd by four motors that looked like starters and had a warning that it would nuke your battery. and i cant remember how much money but it was not cheap. it is a good idea but not pratical at all.
