Supercharger Assembly
Supercharger assembly is a positive displacement pump designed to supply an excess volume of intake air to engine by increasing air pressure and density in the intake manifold. Supercharger assembly incorporates a by-pass system to reduce air handling losses when boost is not required, resulting in better fuel economy. See Fig 1. Supercharger can increase torque across entire engine operating range from 25-50 percent without compromising driveability or emissions.
Supercharger is matched to engine by its displacement and belt ratio, and can provide excess airflow at any engine speed. Drive gears for supercharger are pressed into place and are not serviceable. Supercharger must be replaced as a unit. Supercharger contains 2 belt driven 3-lobed helical cut rotors which are supported by ball bearings in front and needle bearings at the rear. The rotors helical shape and internal specialized porting provide a smooth discharge flow and low noise levels during operation.
