The Motodyne Hydra-drive supercharger.

Was inspired by the B6-B7 S4 BHF series motor. One must look at the S4 engine to appreciate a non-tradtional design. The S4 shares the 4.2L bore and stroke and head design of the previous 4.2L motors only. It's rear cam drive houses 4 timing chains, one that drives a PTO power take off which drives a reverse mounted power steering pump, and reverse mounted AC compressor. It's harmonic balancer drives a 280 Amp water cooled alternator that is plumbed into the 3 front mounted radiators.
