A&A Corvette Secondary Belt Drive System

The A&A Secondary Drive is unique in that it does NOT drive the accessories via the air conditioning belt like other systems. The accessory drive shaft pulley is driven by its own dedicated belt. This allows full belt wrap around the crankshaft pulley as well as the accessory drive shaft pulley and the ability to tension this belt separately. This eliminates accessory belt slip that plagues other systems. The system also utilizes a spring tensioner on the alternator/power steering belt which allows proper belt wrap and tension. Design testing showed the torque needed to slip the accessory drive shaft belt was nearly TRIPLE that of other designs. This eliminates voltage loss at high RPM from slipping, as well as belt squeal in slow corners with the A/C on.The Secondary Drive has been updated with a larger transfer pulley to slow the bearing speed. We are also including a GRIPTEC transfer pulley. Both these modifications help eliminate belt slip without having to run the transfer pul
