ABSTRACT:
The present invention provides a method for mechanically driving a supercharger and a combination harmonic pulley system and supercharger mounted on a powered vehicle including a crankshaft, the supercharger having a supercharger driveshaft and adapted to provide boost air to the intake of the internal combustion engine, driving the crankshaft which rotates the harmonic pulley system. In general the harmonic pulley system includes a harmonic balancer, a drive shaft pulley, a crankshaft bolt, an alignment structure and a drive belt. The harmonic balancer having a first and second ledge, an annular ring and a central aperture, the driveshaft pulley having an inner and outer region, the inner region includes a first shoulder and presenting a pulley aperture aligned with the central aperture, the outer region including a second shoulder and providing an engaging surface. The crankshaft bolt is received by the engine crankshaft through the pulley aperture and the central aperture wherein said driveshaft pulley is compressed towards the harmonic balancer, the first ledge receiving the first shoulder and the second ledge receiving the second shoulder, said annular ring positioned therebetween. The alignment structure aligns the driveshaft pulley with said harmonic balancer and the drive belt encircles the engaging surface and the supercharger driveshaft whereby the supercharger is mechanically driven by said harmonic pulley system.
