A forced air induction system for use with a powered vehicle is disclosed as including a centrifugal supercharger supported by the vehicle's engine and a recirculating induction coolant system that cools the supercharger and the compressed induction fluid provided by the supercharger. The induction coolant system operates by providing coolant to the supercharger and to an intercooler of the forced air induction system. The supercharger case includes internal passageways for cooling the transmission and compressor. The forced air induction system further includes spacers and radiant heat shields for rejecting heat transferred conductively and radiantly from the engine.
