Abstract
A supercharger includes an insert affixed proximate to an air intake structure. Portions of the insert and the air intake structure are removed to enhance airflow into the supercharger. The supercharger body is typically cast aluminum and the insert is typically machined from aluminum. Conventional aluminum alloys may be used.
Claims16
A method for modifying a supercharger for an internal combustion engine to enhance airflow characteristics and supercharger efficiency, comprising the steps of:
- providing a supercharger rotor housing including an air inlet structure that defines an airflow path;
- affixing an insert to a landing portion of the supercharger rotor housing proximate the air inlet structure;
- and
- after the step of affixing the insert, machining an underside of the air inlet structure and, subsequent to machining the underside of the air inlet structure, machining into the underside of the insert, thereby enlarging the airflow path, thereby enhancing airflow through the air inlet structure such that a portion of the insert defines a portion of the airflow path after the machining step.

A supercharger for an internal combustion engine comprising:
- a rotor housing including air intake structure that defines an airflow path and a landing surface proximate the air intake structure, the rotor housing being formed of a metal casting;
- and
- an insert affixed to the landing surface of the rotor housing such that an underside surface of the insert is in contact with the landing surface of the rotor housing;
- wherein a portion of the metal casting proximate the air intake structure opposite the landing surface is machined and a portion of the underside surface of insert is machined, thereby enlarging the airflow path through the air intake structure.
