Supercharger: Description and Operation

Introduction

Air is supplied to the supercharger by an intake cleaner/duct, throttle assembly and induction elbow which are similar to those used for normally aspirated engines. The supercharger delivers pressurized air to two separate charge air cooler units, each unit being mounted on the cylinder bank which it supplies. Pressurized cooled air is fed from the charge air coolers directly into each inlet port.
At closed or partial throttle positions, a by-pass valve opens to direct airflow from the supercharger outlet to its inlet. This effectively inhibits the pressurized charge to the cylinders, reducing engine torque to non supercharged levels. The charge air coolers are water cooled by a radiator and coolant pump.
