Superchargers
Why Supercharge?            Supercharging will give your engine more torque and            horsepower - helping your Corvette work harder.  Everyone uses his or            her vehicle differently, but anyone who simply appreciates performance            can benefit from a supercharger system. 
           Performance.             Superchargers can deliver a proven 63 to 125% increase            in real world "under the curve" power.  Best of all it usually costs            less than 1/3 of a horse at 60 mph cruise. Now that's real efficiency.           
           How Does It Work?             In simple terms, an engine's ability to make power is            directly proportionate to the amount of air and fuel that can be            brought into the combustion chamber.  Putting more fuel in is easy.             It's like opening a faucet.  On the other hand, getting extra air into            the chamber is a more difficult matter, since it's essentially "drawn"            in.  A supercharger increases the displacement or "blows" more air            into the engine.  This is called "forced induction," and it's widely            used in racing, aviation and industry to extract maximum power from            internal combustion engines.  You get the fuel economy of a smaller            engine, with the power and horsepower of a larger, stronger engine.            
           What's Best For Racing Isn't            Necessarily Best For The Street.  A racing            engine is designed to provide peak performance for a certain period of            time.  In drag racing, it's a matter of seconds.  For oval track            racing, it can be 500 miles.  That's nothing compared to the 100,000            plus miles that's expected of a street driven vehicle.
