Abstract: A supercharger for automotive engines utilizing the automobile flywheel as a part of the air compressor means is disclosed wherein air compression type vanes are attached to the flywheel. A donut shaped plenum encompasses the flywheel with the attached vanes, the donut shaped plenum open at its inner peripheral opening to receive air proximate the driveshaft to which the flywheel is attached. The vanes on the flywheel compress the air as the flywheel rotates and deliver the compressed air via an output conduit to the automobile carburetor or to the intake manifold of the engine where it is mixed with gasoline for insertion in the cylinders.
