The A&A "Tuner" 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.
Si-Trim?, T-Trim?, YSi-Trim?
- The Si-Trim is our standard unit and is recommended for all stock engines or engines with mild modifications only. (headers, camshaft, etc.) The Si-Trim is easily capable of 650 RWHP on a mildly modified engine. We see no reason to use a larger supercharger if your aspirations are 650 RWHP or less.
- The T-Trim is recommended for applications up to 750 RWHP. The T-Trim can utilize smaller pulleys and make more boost and power than the Si-Trim.
- The last model is the YSi-Trim. This model is a V-7 which is not self contained. It has straight cut gears and is louder than the V-2 and V-3 units. The YSi is for extremely high output applications and is not recommended for engines with stock pistons.
- The Si and T-Trims are available in two different models. The V-2 Si and V-2 T-Trim superchargers are lubricated with pressurized engine oil. No oil changes will be necessary. Each V-2 kit is supplied with a supply line and fitting, a return line and a special tool to cut a clean hole in the oil pan. The Corvette oil pan is aluminum and of sufficient thickness to allow threads to be tapped in the wall to seal the return fitting. There is no danger of oil leaks if installed according to our instructions.
- The V-3 Si and V-3 T-Trims are basically the same units but are self contained. Each has a sump, holding 4 oz. of supercharger oil and do not require and oil feed or return lines. You will need to change the oil in the supercharger periodically, however. Fortunately the V-3 head units have a convenient drain line attached to the bottom of each unit. This makes oil changes very simple. Both V-2 and V-3 models have helical cut gears and are considered to be very quiet.
