Quick answer: A turbo uses hot exhaust gases (free) to power a compressor that forces intake air into the engine. A supercharger is driven by the engine (via a belt or chain) and uses engine power to do the same thing. So, the turbo wins on efficiency. However, the supercharger is always spinning, regardless of flow through the motor, where the turbo has to 'spin up' when the throttle is opened. So, the super will be more responsive than the turbo, at the cost of a little absolute power and mileage (vast generalization) Bob
