Abstract
A method of designing a supercharger that yields a high isometric efficiency based on a fixed pressure ratio, a plurality of rotor leads and a plurality of rotor operating speeds is provided. An efficiency map is generated of rotor lead versus rotor operating speeds for the fixed pressure ratio. A rotor lead value is determined based on the fixed pressure ratio and rotor speed combination from the efficiency map that yields a high isometric efficiency. A supercharger is provided having the determined rotor lead and that is configured to operate with the fixed pressure ratio and the determined rotor operating speed.
