How to Buy The best supercharger is the one that matches the airflow demands of your engine. Get one that is sized to deliver the right amount of air, and you can fine-tune boost levels with pulley changes. Tell your sales rep the specs on your engine-cylinder heads, compression ratio, cast or forged internals-and your primary driving style. Also be sure to tell him how much power you want to make, how fast you want your car to go, and what type of fuel you will run. The more information you give, the better he can match his product to your application. For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. These new-tech blowers are much more efficient than GMC-style Roots blowers. And their compact size allows them to fit a wide variety of engines and engine compartments. For a big drag engine, stick with the GMC-Roots. We also want to stress the importance of running a charge cooler with the supercharger, though most of the kits available come with some sort of heat exchanger usually fitted in the manifold below the supercharger. The cooler the intake charge, the more power you will make. A supercharger is an excellent performance buy, and you'll typically drop on 50 to 100 hp in a weekend's work.
