This page is dedicated to the 2014-2017 C7 Corvette Supercharger Systems manufactured by our 3rd Party Manufacturer - A&A Corvette.
The A&A Supercharger kit brings you dramatic increases in power while not degrading everyday drivability or highway gas mileage! The system utilizes a large blow off valve that remains open at cruise and light throttle. This, essentially, allows the supercharger to “freewheel” under normal conditions, reducing parasitic loss to less than that of an alternator.
A naturally aspirated engine would require higher compression, a very aggressive camshaft, high flow cylinder heads with heavy duty valvetrain, exhaust headers with free flowing exhaust, larger throttle body, high flow intake manifold, free flowing air filter housing and duct, etc. Most of these parts are NOT emissions legal. The price of these components alone is higher than a supercharger system. The labor to install these is also much higher. Then there are the inherent problems brought to the vehicle by such a build. A large camshaft all but ruins everyday drivability AND gas mileage. Driving in traffic becomes a very trying experience. A stick shift car will buck and surge and an automatic car will be hard to hold back because of the increased idle speed required. Low speed torque is reduced with an aggressive camshaft which will require lower differential gearing and a high speed stall torque converter (automatic cars) to make up for it. This further degrades drivability and gas mileage. With all the components required for a high performance naturally aspirated car, the degradation in drivability and gas mileage, the total inability of the vehicle to pass emissions tests and the added expenditure, the vehicle would STILL have up to 100HP less than a stock Corvette with one of A&A's standard systems bolted on.
Average increase TO THE REAR WHEELS is approximately 175 RWHP! No other modification, in this price range, even comes close.
A&A SYSTEM ADVANTAGES OVER THE COMPETITION
Emissions - A&A Corvette produces the ONLY 50 State Legal centrifugal systems available as per C.A.R.B. EO# D-707-1.
While this may not be of concern to those in non-emissions areas, it does show the time and effort spent engineering a system that can give you the power you want and still pass the rigorous testing required to be 50 State Legal. The other manufacturers didn’t even try. Of course, A&A also offers non-emissions race setups capable of enormous horsepower for racing of all kinds.
A&A Corvette utilizes proprietary supercharger units built specifically for A&A Corvette by Vortech Engineering. A&A have found Vortech to build the most efficient units available and to also offer the best available customer service and support.
Self-contained V3-Si or V3-Ti head units are standard. A&A have seen the Si Trim pushed beyond 700 RWHP many times but they are the most efficient unit available for the 500 to 600 Rear Wheel Horsepower (RWHP) daily driver and the only one used in the C.A.R.B. compliant kits. For those looking to rule the streets in the 700 RWHP neighborhood (in non-emissions areas) and have the proper supporting modifications such as Methanol Injection, headers, or performance camshafts, then the V3-Ti Trim (A NO COST OPTION) is a better choice. The V7-YSi is strictly for vehicles with forged internals and or larger displacement and capable of over 1000 RWHP.Superior Intercooler Design
A&A has designed a special Ram Air Intercooler for their C7 Corvette systems. GM did a great job sealing in the radiator cavity from the grill opening to the radiator. This whole cavity is being packed with air when the vehicle is at speed. After carefully looking at all placement and airflow direction options, they came up with their present design. The intercooler lays flat and is hidden behind the bumper cover. An aluminum scoop is welded to the intercooler which protrudes into the incoming air stream and directs it through the intercooler and out the bottom. Any air that is grabbed by the scoop is literally rammed through the intercooler core. Simple physics won’t allow it to go anywhere else. Hence the name “Ram Air Intercooler”.
Standard SFI Approved Harmonic Balancer With Interchangeable 8 or 10 Rib Pulleys
A&A is the only manufacturer to include a fully machined SFI approved balancer with interchangeable lower pulleys as standard equipment in their supercharger systems. A&A Corvette stocks 8-Rib and 10-Rib pulleys in sizes ranging from 7.65” to 8.35”. This balancer design allows the use of a dedicated 8 or 10 rib belt that does not interfere with the water pump or alternator belt.
With an all aluminum case design for lower rotating mass, stress-proof steel hub and 1040 steel internal inertia rings for outstanding durability, these balancers are a great investment for your street or race vehicle and come standard in all A&A Corvette C7 supercharger systems
Inside the light weight billet aluminum cover is a free floating wet friction clutch pack assembly that utilizes spring loaded inertia rings to dampen crankshaft harmonics over a wide RPM range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and a small amount of fluid is used inside that acts as a lubricant as well as dissipates heat to the outer body.Innovative Tensioner Design
The A&A Corvette tensioner design stands out from the crowd. Each solid billet tensioner starts out as 9.6 pounds of 6061 aluminum bar, has 3 internal spring pressure settings and is adjustable to accommodate larger balancer pulleys. It is the only tensioner on the market that features a lockout mechanism. The tensioner is easily locked in the open position for painless belt installation.
Both the main bracket and tensioner are clearly stronger than anything on the market. These tensioners have precision bearings riding on a machined chromoly center shaft and are fully rebuildable. Each one is hand built and tested for spring pressure, bearing clearance and alignment. Spring pressure is set per your particular application. There is even an optional spring available for extreme applications.Top Quality Components
