Engine Performance: System: Supercharger: Operation

The supercharger is a blow-through type system with port fuel injection. The supercharger is belt driven off the crankshaft. The throttle body controls amount of intake air to the supercharger through the inlet plenum.

Air from supercharger is routed through the intercooler and then to the intake manifold. At partial throttle or when vacuum is present in the intake system, a vacuum controlled by-pass valve reroutes some discharged air from supercharger back through intake plenum to prevent supercharger cavitation.
