A&A Corvette produced the first C7 Corvette supercharger system in October of 2013. After much testing and a few “tweaks” here and there, production systems became available in January of 2014.
Aesthetically as well as mechanically, we believe this to be the finest system available for the new C7 Stingray. Take a closer look, compare it with our competitor’s product, part for part, and we’re sure you’ll agree.
We’ve prepared this page so you can take a close look at our systems and see each component in detail. Anybody can brag about their system doing this or that or have some vague pictures that don’t really show you anything. We’re willing to show you every detail. No hype, just as close a look as we can give you of our products. As they say, “A PICTURE IS WORTH A THOUSAND WORDS”.

8 Rib Belt Drive System
The A&A System is the most technologically advanced centrifugal supercharger system available today. With our Ram Air Intercooler design, included SFI approved balancer, adjustable billet tensioner, we have applied everything we’ve learned in the last 15 years to produce our best system yet.
We know Corvette owners are discerning when it comes to under hood appearance. While engineering the performance side of this kit, we kept that in mind. Our system is as beautiful as it is powerful. Available in fully polished or satin black finishes.
A&A is the only company producing a CARB compliant system for the C7 Corvette. Please call or email for emissions compliancy information.
If you’d like to have a closer look at any particular part we may have overlooked, ask us. We’ll either send you pictures or add them to the website. To be fair, we would ask you to have our competitors do the same so you can make an honest comparison. You can then make an educated decision as to whether the A&A Supercharger System is for you.
We invite head to head comparisons from any manufacturer, although you may find it hard for them to take the challenge! If they won’t, there must be a reason?
We produce the ONLY 50 State Legal centrifugal systems available as per C.A.R.B. EO# D-707-1 & 707-2 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, we also offer non-emissions race setups capable of enormous horsepower for racing of all kinds.
BIG POWER FOR RACING APPLICATIONS WITH PROPER ENGINE SETUP
Our systems are quite capable of making more than 1000 horsepower for drag racing applications. From mild street applications to dedicated racers, we have it all.
Our proprietary supercharger units are built specifically for A&A Corvette by Vortech Engineering. We have found Vortech to build the most efficient units available and to also offer us the best available customer service and support. We are less than 10 miles from the Vortech factory and work hand in hand with them on a daily basis.
Self-contained V3-Si or V3-Ti head units are standard. We 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 our 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.
A&A is the only manufacturer to include a fully machined SFI approved balancer with interchangeable lower pulleys as STANDARD EQUIPMENT. We stock 8 rib and 10 rib pulleys in sizes ranging from 7.65” to 8.35” Others just use a simple pulley that bolts to the stock cast iron balancer, with no choice in sizes. This balancer design allows us to use a dedicated 8 or 10 rib belt that does not interfere with the water pump or alternator belt.
Both our competitors chose to bolt a machined add-on pulley to the existing cast balancer. How is that to be expected to run true? The ONLY benefit to using a pulley like this is to the manufacturer because it is CHEAPER.
Our competitor charges $525 extra for a balancer like this! And $1100 extra for the 10 rib!
ABOUT THE BALANCERS WE USE
With an all aluminum case design for lower rotating mass, stress-proof steel hub and 1040 steel internal inertia rings for outstanding durability, our balancers are a great investment for your street or race vehicle and come standard in ALL our 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 we use a small amount of fluid inside that acts as a lubricant as well as dissipates heat to the outer body.
RAM AIR INTERCOOLER DESIGN
A&A continues as the leader in intercooler design with our new C7 Ram Air Intercooler. 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, we came up with our present design. The intercooler lays flat and is hidden behind the bumper cover. We weld an aluminum scoop 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”.
Others went with the flat placement but forgot all about directing airflow through the cooler. Laying the intercooler flat and putting a plastic air dam behind it just isn’t going to work efficiently. Not only are they asking the air to abruptly make a right-angle turn, they’re also trying to get the air to flow from a low pressure area (under the car) into a high pressure area (inside the radiator cavity.) A&A wins this one hands down.
Our tensioner design once again 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. Our 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 application. We even have an optional spring for extreme applications. Our $400 precision tensioner vs. a $60 truck tensioner. It’s your call. Which is better? Our competition just can’t compete with that!
Our bracket uses solid billet mounts that attach the main bracket to the block and the cylinder head. Our cylinder head mount has FOUR mounting points. Others use a simple dowel with a long bolt, or worse yet, a threaded rod going through the middle that can twist under extreme forces. Obviously, this is much cheaper but clearly not as strong. Ours simply cannot move in any direction.
We use steel idler and tensioner pulleys with dual bearings and the proper stanchions to properly support the bearings. Every aspect of this bracket and tensioner setup has been analyzed and optimized. Nothing else even comes close!
Our adjustable sliding idler, along with our adjustable billet tensioner, allows for full adjustment of both belt tension and wrap.
Even better for the consumer is that the entire bracket, pulley and supercharger assembly comes completely preassembled for you. Take it out of the box and bolt it onto the block and cylinder head without having to assemble a thing. Even the mounting bolts are “zip-tied” in the proper holes. It really is a 5-minute proposition to bolt the entire supercharger and bracket assembly on the engine.
We make a specific bracket for 2014 and 2015 and up. When GM changed the water pump for 2015 we immediately designed a new bracket to accommodate the change. Why? It never crossed my mind to do otherwise. What did one of our competitors do? They just added $300 to the price to cover the cost of a 2014 water pump housing. Again, A&A FOR THE WIN!!
