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.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is: 1. A harmonic pulley system in combination with a supercharger mounted on an internal combustion engine including a crankshaft, the supercharger having a supercharger driveshaft powered by said harmonic pulley system to provide boost air to the internal combustion engine to drive the crankshaft, rotating the harmonic pulley system, said harmonic pulley system comprising: a harmonic balancer having a first ledge, a second ledge, an annular ring and a central aperture, a driveshaft pulley having an inner and outer region, said inner region including a first shoulder and presenting a pulley aperture aligned with said central aperture, said outer region including a second shoulder and providing an engaging surface, a crankshaft bolt received by the crankshaft through said pulley aperture and said central aperture wherein said driveshaft pulley is compressed towards said balancer, said first ledge receiving said first shoulder, said second ledge receiving said second shoulder, said annular ring positioned therebetween, alignment structure for aligning said driveshaft pulley with said harmonic balancer, and a drive belt encircling said engaging surface and said supercharger driveshaft whereby said supercharger is mechanically driven by said harmonic pulley system. 2. The combination apparatus of claim 1 wherein said alignment structure further comprises: a plurality of pin receivers located in said harmonic balancer, and a plurality of pins extending from said driveshaft pulley through said pin receivers whereby said pins limit any rotational slippage between the harmonic balancer and the driveshaft pulley. 3. A harmonic pulley system mounted on a vehicle engine including a crankshaft, said harmonic pulley system comprising: a harmonic balancer having a first ledge, a second ledge, a plurality of pin receivers, an annular ring and a central aperture, a driveshaft pulley having an inner and outer region, said inner region including a first shoulder and presenting a pulley aperture said outer region including a second shoulder, a crankshaft bolt received by the crankshaft through said pulley aperture and said central aperture wherein said driveshaft pulley is compressed towards said balancer, said first ledge receiving said first shoulder, said second ledge receiving said second shoulder, said annular ring, positioned therebetween, and a plurality of alignment pins extending from said driveshaft pulley and through said harmonic balancer at said pin receivers whereby said pulley aperture of said driveshaft pulley is aligned with said central aperture of said harmonic balancer. 4. The combination apparatus or claim 1 wherein said alignment structure further comprises: said harmonic balancer including a plurality of radially extending spokes; and a plurality of alignment pins extending from said driveshaft pulley, said pins aligned with said spokes whereby said pins limit any rotational slippage between the harmonic balancer and the driveshaft pulley. 5. The combination apparatus of claim 1 wherein said alignment structure further comprises: said harmonic balancer including a plurality of radially extending spokes; a plurality of pin receivers aligned with said spokes; and a plurality of pins received by said pin receivers whereby said receivers limit any rotational slippage between the harmonic balancer and the driveshaft pulley. 6. A harmonic pulley system mounted on a vehicle engine including a crankshaft, said harmonic pulley system comprising: a harmonic balancer having a first ledge, a second ledge, a plurality of radially extending spokes, an annular ring and a central aperture, a driveshaft pulley having an inner and outer region, said inner region including a first shoulder and presenting a pulley aperture said outer region including a second shoulder, a plurality of pin receivers adapted to limit any rotational slippage between the harmonic balancer and the driveshaft pulley, a crankshaft bolt received by the crankshaft through said pulley aperture and said central aperture wherein said driveshaft pulley is compressed towards said harmonic balancer, said first ledge receiving said first shoulder, said second ledge receiving said second shoulder, said annular ring positioned therebetween, and a plurality of pins extending through said driveshaft pulley and through said harmonic balancer and received at said pin receivers wherein said driveshaft pulley is aligned with said spokes of said harmonic balancer.
