C5 and C6 SECONDARY DRIVE -V3- LATEST DESIGN

Description

UPDATED INSTRUCTIONS

 Our updated dynamic tensioner design is much easier to install. We now have separate spring tensioners for each belt that automatically compensate for belt stretch. Belt squeal and slip are now a thing of the past. The lower tensioner has a locking pin, much like our famous billet tensioner used on our supercharger brackets. You literally slip the belt on, pull the locking pin, and your belt tension is set!

We’ve also changed the transfer pulley to a triple bearing 3 1/2″ GRIPTEC pulley. The larger diameter slows the bearing speed for longer life while adding more surface area for belt traction. The GRIPTEC surface preparation further enhances traction.

 Currently available cog drive systems have their inherent flaws. Cog belts MUST have a guide pulley to keep the belt from moving fore and aft. Even a small amount of movement can allow the cog belt to contact the A/C belt. There is no  guide pulley between the crank pulley and drive pulley on current systems.  Drive belt tension is also critical with a cog drive system. Setting the tension properly on a cold engine will automatically make it too tight when hot. Current cog drive systems do not have a dynamic tensioner to compensate for temperature or stretch. 

 The A&A Secondary Drive System takes care of both these issues. The multi groove drive belts cannot move fore and aft and our dynamic tensioner corrects tension for temperature and stretch. 

The A&A Secondary Drive is unique in that it does NOT drive the accessories via the air conditioning belt like other systems. The A/C belt remains untouched. 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. Our system also utilizes a spring tensioner on each belt which always provides proper belt wrap and tension.

• Design testing showed the torque needed to slip the accessory drive shaft belt was over 4 times that of designs that use the A/C belt to drive everything. This eliminates voltage loss at high RPM from slipping, as well as belt squeal in slow corners with the A/C on.
• A properly designed serpentine system is inherently more reliable than a cog system. Cog belts tend to drift from side to side with nothing to guide them. Serpentine belts do not have this problem.
• This kit INCLUDES our PROPRIETARY 8 RIB SFI approved 10% OVERDRIVE BALANCER, all belts, hoses, pulleys and tensioners needed. (Will NOT work with stock, or standard Innovators West or ATI balancer)

Using our Secondary Drive allows the use of a much shorter belt to drive the supercharger which eliminates stretch and belt whip. This is the ultimate belt drive system for street driven C5 and C6 Corvettes as well as dedicated race cars with or without A/C.

Requires modification of the stock alternator/power steering bracket. (Or add our brand new OEM modified bracket at checkout.)

 PRICE INCLUDES OUR PROPRIETARY 8 RIB OVERDRIVE SFI SPEC BALANCER.

Please check the box below if you have an LSX block. There is a large plug in the block and we need to machine a relief in the lower bracket for clearance.
