Abstract
An induction assembly for a supercharged internal combustion engine includes a housing and a supercharger with a rotor and gear plate assembly to produce pressurized air. The housing includes a rotor casing which defines a central chamber to house the rotor and gear plate assembly. The housing also includes a suction inlet to introduce air to the central chamber and an outlet to discharge pressurized air from the central chamber to a plenum. The housing further includes intake runners which are in fluid communication with the plenum. The intake runners are radially adjacent to the exterior of the rotor casing such that the rotor casing comprises the inner wall of the intake runners. The plenum is defined by a removable cover and the housing. The removable cover has a central lengthwise bead and rounded surfaces resulting in the plenum being rounded and divided longitudinally. This plenum shape provides a smooth redirection of air flow exiting the supercharger and distributes the pressurized air to the intake runners.
