ABSTRACT:
A housing for a supercharger assembly is provided having an inner wall at least partially defining a rotor cavity. A layer is formed from a sacrificial polymeric material and is provided on at least a portion of the inner wall. The layer is operable to provide approximately zero running clearance and improve scuff resistance between the first and second rotors and the inner wall. The sacrificial polymeric material is applied to the inner wall by insert molding to form the layer. A method of forming the housing is also provided.
