A&A Secondary Belt Drive System PLUS our Supercharger mounting bracket at a discounted price.
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 those plagues other systems. Our system also utilizes spring tensioners on the alternator/power steering belt, as well as on the accessory drive shaft, which allows proper belt wrap and tension. The spring tensioners continually take up any slack in the belts.
Our 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, while the spring tensioners keep the belts at the correct tension.
Our lower spring tensioner comes with a lock pin, much like the billet tensioner on our main bracket. You literally slip the belt over the pulley and pull the pin. That’s it. The belt tension is set.
- Design testing showed the torque needed to slip the accessory drive shaft belt was FOUR 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.
- 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 modified bracket at checkout.)
PRICE INCLUDES OUR PROPRIETARY 8 RIB OVERDRIVE SFI SPEC BALANCER.
ALSO INCLUDES THE A&A SUPERCHARGER BRACKET WITH ADJUSTABLE BILLET TENSIONER
Each plate is machined on both sides to assure absolute flatness and accuracy. Super strong bracing, Grade 8 hardware, all steel pulleys with dual bearings, stainless or aluminum stantions for proper bearing support and our adjustable billet tensioner are all standard. Our brackets are also set up to use 6 or 8 rib drive pulleys without modification, right out of the box.
Our bracket assemblies have often been described as “jewelry”. Look at the overall quality of the machine work and components. It really is a work of art.
Combined with our billet tensioner, the A&A bracket offers unsurpassed belt wrap on the supercharger pulley as well as the crankshaft pulley for exceptional grip.
Each tensioner is machined from 9.6 pounds of 6061 Aluminum bar. The shaft is precision machined 4340 Chromoly steel. The tensioner rotates on German manufactured bearings that are precision fit much like an engine bearing. The bores are set for a certain amount of “crush” so that the shaft to bearing clearance is within the range specified by the bearing manufacturer.
That’s the quality side of the tensioner assembly. On the practical side, we have 2 internal spring settings. A 1000 HP drag racer obviously needs more spring pressure than a 600 HP daily driver, right? This can be accomplished with just one tensioner! We even have an optional spring for super high horsepower drag racers. There is also a “lock pin” so the tensioner can be rotated to the slack position and locked in place. This is a huge help when installing a belt, changing an alternator etc. Fighting the spring tensioner is a thing of the past.
No other manufacturer has a tensioner that is even close to ours in both quality and practicality.
Each one is hand assembled at our facility and checked for proper operation and spring tension with a digital torque meter. NOBODY else does that but A&A!
This complete drive system is a combination of our mounting bracket with adjustable billet tensioner and our Secondary Drive. Buying the combination together allows us to offer you a discount price.
Our 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 pulley belt so tight.
