"Supercharging" is the general concept of pumping air into the engine. However, the devices splits into turbochargers (exhaust driven) and superchargers (mechanically driven). A compressor is a supercharger. This terminology is probably due to the fact that superchargers were used in the beginning. Superchargers are easier to control than turbos. A turbo tends to give either too little or too much boost if not carefully controlled. Modern computer control makes this much easier. Johannes
