Abstract
A supercharger constructed in accordance to one example of the present disclosure includes a housing, a first rotor, a second rotor and a rotor shaft assembly. The first and second rotors are received in cylindrical overlapping chambers of the housing. The first rotor has a central longitudinal passage. The rotor shaft assembly rotatably supports the first rotor and includes a first rotor shaft and a separate and distinct second rotor shaft. The first and second rotor shafts are press-fit into the central passage defined in the first rotor.
