it's a compressor. typically a belt drive by your crank puelly (just like your a/c or alternator) turns the compressor. so the crank driven work does the compressing as opposed to the exhaust gas driven turbine of a turbo. belt turns the compressor (supercharger), which compresses the air.


air comes in your intake, supercharger compresses it then it goes into your throttle body/intake manifold. of course there are sensors and intercoolers (hopefully) in between.
