I'm driving a 96 Buick Riviera right now. My question is, it has a blower in it already, will a smaller little wheel thingamabob on the charger and a tighter belt make the supercharger pump out more power? I'm not sure, and I don't want to mess up the car so I'm asking here first. But as I understand it, the more you make the wheel thing on the supercharger spin, the more it works, therefore more psi right? Anyways, so if I am right, and I did put a smaller...pulley is it?...and then put the corresponding belts so there will be no slack, will I have to take it somewhere to get it tuned if it does pump out more psi and produce more horsepower? Also, the engine it has is a 3.8, V6. Basically the same ones in the Pontiac Grand Prix's. Anyone care to enlighten me a bit, cuz I do feel it needs more power, and this seems to be the quickest way possible to add more horses.
