A&A's proprietary supercharger units are built specifically for A&A Corvette by Vortech Engineering. They have found Vortech to build the most efficient units available and to also offer us the best available customer service and support. They 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. A&A has 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 their 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.
ABOUT THE BALANCERS
A&A is the only manufacturer to include a fully machined SFI approved balancer with interchangeable lower pulleys as STANDARD EQUIPMENT. They 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.
With an all aluminum case design for lower rotating mass, stress-proof steel hub and 1040 steel internal inertia rings for outstanding durability, A&A's balancers are a great investment for your street or race vehicle and come standard in ALL their 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 they 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 their 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, A&A came up with their present design. The intercooler lays flat and is hidden behind the bumper cover. They 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.
INNOVATIVE TENSIONER DESIGN – LIKE NO OTHER
A&A's 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. Their 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. They even have an optional spring for extreme applications.
STRONGEST AND MOST ADJUSTABLE MOUNTING BRACKET ON THE MARKET (BEST LOOKING TOO!)
A&A's bracket uses solid billet mounts that attach the main bracket to the block and the cylinder head. Their 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. It simply cannot move in any direction.
A&A uses a 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!
The adjustable sliding idler, along with their 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.
CUSTOM FORMED 4 PLY NYLON REINFORCED CHARGE HOSES
A&A once again took the more expensive but superior option of having custom formed, reinforced silicone charge hoses manufactured. The custom silicone hoses navigate around the various obstacles in the C7 engine bay and make installation much easier. Using a one-piece silicone hose from the supercharger to the intercooler and from the intercooler to the MAF tube allowed them to fit an intercooler that is 4” wider than others on the market and make a smooth transition from the 3” outlet to the 3 ½” MAF tube. Reinforced silicone hoses don’t rattle, leak or expand under pressure. Their blowoff valve mount is also integrated into the one-piece hose.
