A&A Corvette Performance is an independent manufacturer of custom supercharger systems for the C5 and C6 corvette, exclusively. Our systems have evolved into the most technologically advanced centrifugal systems available today. With over 500 systems on the road and hundreds of additional hours spent analyzing how every part of the system could be potentially improved, it has evolved into the finest system available. Look closely at our system vs. all others. The fit and finish of all components is second to none. This commitment to aesthetics carries forward in the same commitment to function.
Our bracket and pulley design offers excellent alignment and belt wrap. This is essential in any supercharger system and is unsurpassed by any other manufacturer. Our intercooler design also differs from any other. Not only are our intercoolers as large as practical for a Corvette, but the placement and attention given to airflow management is unmatched. An intercooler must have as much ambient airflow through the core area as possible to be efficient. Our design is the only one that is 100% exposed to frontal airflow either directly (C6) or through the use of directional scoops (C5). Not one square inch of either intercooler is shrouded by the frame or bodywork. Airflow through the rear of the intercooler is also important. Most designs place the intercooler tightly against the radiator and air conditioning condenser. We place our intercoolers with a large space between these components which aids in airflow through the intercooler as well as airflow to the radiator and condenser. The inlet duct from our high flow air filter to the supercharger inlet is also designed with superior airflow in mind. The curves are smooth and cross sectional area is large. This all translates into lower inlet temps and more power output.
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 our 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
Superior Belt Drive System
Belt wrap is the key to eliminating belt slip and our proprietary bracket system offers more belt wrap than any other system on the market.
Our bracket is CNC machined from 5/8” high quality 6061 aluminum plate and fly cut on both sides to assure absolute consistency in thickness. This is imperative for proper belt alignment.
Our brackets are constantly quality checked by assembling on our “mock up” engine and checking alignment with a laser aligner.
Superior Intercooler Design
Our intercooler design has evolved, through constant testing, into the most efficient intercooler system available for the late model Corvette.
Our intercoolers rely on superior “air management” of the charge air as well as the ambient cooling airflow. Both are equally important and are often overlooked by the competition. With the limited space available in a Corvette, positioning of the intercooler is critical.
A large intercooler that is hidden behind the frame is not as efficient as a smaller intercooler that is exposed to full frontal airflow.
We not only use a large intercooler, but we are able to ram more cooling air through the core with our “Ram Air” intercooler design. The integral scoop captures air from under the front fascia and forces it through the core. The entire core is exposed to this cooling air stream.
Other designs allow air to travel over and around the intercooler.
The interior of our intercoolers differ from the competition also. We utilize directional vanes in the lower tank to direct charge air evenly across the intercooler core. This is an expensive but very important addition.
Superior Engine Cooling
Intercooler positioning is equally important in how it affects engine cooling. Many supercharger systems are plagued by overheating issues due to intercooler placement. Our intercooler is placed much further forward than any other design. This allows the fans to draw cooling air through the radiator and AC condenser without being shrouded by the intercooler.
We also leave the radiator mounted in its upright position for better cooling. Some competitors lay the radiator down at a steep angle which impedes air flow through the radiator.
The A&A system is one of the best looking systems around.
Fit and finish is second to none. Our brackets, ductwork and the supercharger, itself, are all show polished.
Our top shroud fits perfectly and is powder coated satin black to compliment the polished components.
All the visible couplers are high quality silicone and our “T Band” clamps are polished stainless steel.
The entire system fits snuggly under your stock hood.

Trim Specification Selection:
Vortech V-2 head units are similar to the V-1 superchargers where the supercharger will require an oil feed line and oil drain line. The major difference is they are using helical gears inside of the gear casing. What are helical gears? Helical gears are gears that are cut diagonally instead of straight. These Helical gears help eliminate a lot of the gear noise that is common in the Vortech V-1 superchargers. You will still hear the whining sound, but the chattering sound caused by the gears is significantly quieter. This is why Vortech names their V-2 compressors SQ, which stands for, “Super Quiet.”
The Vortech V-3 supercharger is the latest release in superchargers from Vortech. Unlike the Vortech V-1 and V-2 supercharger, the Vortech V-3 does NOT require any oil lines to feed the supercharger gears with oil. The Vortech V-3 supercharger has an internally lubricated transmission. This internal lubricated gear case requires for the supercharger oil to be changed with Vortech’s special supercharger oil. The Vortech V-3 supercharger also comes with helical gears to make the overall gear noise quiet, but still allows you to hear the sweet whine sound that we all love about superchargers.
Now that we got the transmissions out of the way, it is time to talk about the labeling of their impellers and compressor size.
Vortech is known for having one of the most diverse selections of supercharger compressors around. Vortech makes well over 15-difference sizes of superchargers all in which have different power bans depending on ones vehicle needs. The most common ones are Si-Trim, T-Trim, and YSi-Trim.
The SCi-Trim is one of Vortech’s smaller type superchargers. These are commonly found in smaller displacement engines and some entry-level supercharger kits. The SCi-Trim does come in a V-1, V-2, and V-3 transmission.
The Vortech Si-Trim is by far Vortech’s most commonly used supercharger. These superchargers are great for both street and strip use. You will find these in their Mustang 4.6L & 5.0L supercharger kit, Vortech’s 5.7L & 6.1L Dodge and Chrysler Hemi kits, and Vortech’s Hummer H2 supercharger systems. The Si-Trim also comes in a V-1, V-2, and V-3 transmission.
For those seeking more power for street and strip, Vortech makes a T-Trim for these power seekers. The T-Trim really shines for those who have a modified engine that flows good and are seeking to run boost levels in the 12-18 psi range. The Vortech T-Trim is normally the next blower size up from the Si-Trim once people max it the Si-Trim. The T-Tim only comes in two types of transmissions, which is V-1 heavy-duty, or V-2 also known as a “TSQ”. The V-2 version is a non heavy-duty transmission, which means it is not idea for cog pulleys.
