Abstract:
1. A supercharger assembly for delivering pressurized air to an internal combustion engine, the supercharger assembly comprising: a centrifugal blower including an inlet for receiving air, a rotatable impeller and vanes for pressurizing the air, and an outlet for delivering the pressurized air to an engine air manifold of the engine; a variable transmission for driving the impeller of the blower, the variable transmission including— a motor for adjusting at least one of the drive pulley or the driven pulley to adjust a gear ratio of the variable transmission; a programmable controller for controlling operation of the motor in accordance with user selectable inputs and sensed operating parameters of the engine to control a boost performance of the supercharger assembly; and a speed multiplier gear assembly connected between the variable transmission and the blower for increasing rotational speed of the blower impeller.
