A supercharger is a mechanical device that increases the air intake of an internal combustion engine. Some synonyms for supercharger include blower, turbocharger, compressor, and boosted. A blower is a supercharger that utilizes an external belt to compress air into the engine. A turbocharger works on the same principles as a blower but uses exhaust gas to power a turbine and compress air. A compressor is any machine that increases the pressure of a gas or air, but in the automotive industry, it refers to a supercharger. Boosted is a slang term used to describe a vehicle that has been fitted with a supercharger or turbocharger to increase performance.
