turbo's or superchargers....well, the turbo takes energy essentially wasted (exhaust) and puts it to good use, the supercharger uses power to make power....the turbo also takes a little longer to kick in than a supercharger does...turbo you can select boost settings by simply turning a knob, instead of having to turn wrenches and change a pulley out, so which do i think is better?...NAAWWZZZ
