The centrifugal supercharger works differently. It basically freewheels until you put enough load on the engine to drop the vacuum down to near zero. At that point the blowoff valve closes and the charger starts making boost. Until that point, the computer is still in cruise mode with full timing and a lean fuel mixture.

Will a roots or twin screw make more power at low RPM? Absolutely. The question is, is that what you really want or need? more...

Ah, yes the centrifugal supercharger. We choose Vortech. Polished finish is standard.

The V-2 Si-Trim is now the standard in A&A Corvette supercharging systems. This new supercharger is equipped with enhanced high-performance compressor stages, allowing for greater airflow, boost pressure and power gain potential. These new compressors are a product of Vortech's latest research and development process. The Si-Trim is capable of operating at a peak efficiency of 78% - an impressive 6% improvement over the S-Trim's already class-leading performance. Not only does a more efficient supercharger produce a cooler air charge, it also allows for reduced engine load which results in greater net horsepower and torque gains.

While the V-2 Si-Trim is standard (and has shown itself to be 700RWHP and 9 sec 1/4 mile worthy), you can upgrade to a V-2 T-Trim, V-3 Si-Trim, V-3 T-Trim, V-7 JT-Trim, or V-7 YSi-Trim Supercharger!

The A&A Corvette C6 Ram Air Intercooler

The A&A Corvette C5 Ram Air Intercooler

• Our intercooler design has evolved, through constant testing, into the most efficient intercooler system available for the C6 Corvette.
• Our intercoolers rely on superior “air management” of the charge air as well as the external 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. Our intercooler is as large as any available but it’s placement is the key to superior charge cooling. The entire core is exposed to the cooling air stream.
• The top of the intercooler core is positioned right at the bottom of the frame. It is mounted forward so as not to allow air to flow over the top of the intercooler.
• We have side panels and a larger bottom panel that seals up against the front fascia.
• This gives us a “Ram Air” effect through our intercooler. No other manufacturer has spent as much time and resources on air flow management as A&A.
• Looking through the grill opening on an A&A system will reveal the difference between our system and all others. Nothing but the core area of the intercooler is exposed to the incoming rush of cold air. The intercooler face in encompassed by our sheet metal enclosure and both tanks are completely hidden from view.
• The area next to the intercooler is also closed in with aluminum panels assuring that any air that is fed around the sides of the intercooler is redirected back into the radiator. Again, this is something no other manufacturer has incorporated into their systems.
• Other designs allow the upper portion of the intercooler core to be shrouded by the frame and allow air to travel over and around the intercooler. When looking through the grill opening on other systems, you see the lower tank and only a portion of the core. This is horribly inefficient!

• 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.

• Blow-off Valves improve supercharger operations by opening to relieve unwanted pressure during deceleration. This reduces heat build-up and eliminates compressor surge
• Flows 320 CFM @ 8 PSIG
• This aluminum piece is standard in our systems, not the cheap plastic valve
• We also include a filter to quiet down the valve

For your LS1/LS6/LS2/LS3/LS7, we supply you with 60lb injectors.

All A&A supercharger systems (except tuner kits) come complete with the appropriate fuel delivery system for their application and horsepower output. There is no need to purchase anything additional unless your boost and horsepower are raised beyond the capacity of the standard systems. More on Fuel Systems here.

Forced inducted cars need colder plugs. The kit will come with a set of one heat range colder (TR-6) spark plugs.

Crank pinning kit that includes a new factory GM crank bolt.

All visible connections are made with High Quality Stainless Constant Tension clamps. While the traditional worm gear clamps get the job done, these clamps have a cleaner looking appearance. Not only are they good looking, but the spring action within the tensioning screw compensates for heat expansion and cooling contraction of supple silicone hose. Constant tension means the lowest possible risk of boost leaks.

The little things, let's take our idler pulley that goes on the automatic tensioner as an example. We have a spacer machined for us to fit in the pulley. Pretty sweet setup. We have seen other kits that use just a washer in this situation. Tightening the Bolt only bends the washer!

A&A Corvette's Supercharger kits produces more power out of the box than even the most radical head and cam package that we have done. How much more power? We put together some charts to show the differences between stock, supercharged, and cars with radical head and cam jobs. Also take into consideration the price of these modifications. Our kits are normally $5995.A cam and head package tuned like we show in these graphs will run you around $5500, which does not include headers, underdrive pulley, intake, etc.
