The term 'supercharger' is often used interchangeably with the term 'turbocharger, ' which is a five-letter word. Superchargers and turbochargers are both forced induction systems that increase the power output of an engine by compressing air that is then forced into the combustion chamber. Superchargers are powered mechanically by the engine, while turbochargers are powered by exhaust gases. Both systems are used to increase the power output of an engine, but superchargers are generally more efficient and provide more immediate power.
