How is a supercharger different from a turbocharger?
A supercharger is connected directly to the crankshaft by a belt unlike a turbocharger which is driven by exhaust gases. The improved horsepower and torque, at lower engine rpm’s, is obtained by pumping extra air into the engine in direct relationship to crankshaft speed. The positive connection yields instant response, in contrast to tubochargers, which must overcome inertia and spin up to speed as the flow of exhaust gas increases. The supercharger has self contained oil whereas the turbocharger requires engine oil.
