Your engine just is not putting out the power that you know it could, and nothing you have done so far has solved the problem. Then a buddy mentions that you should put a Powerdyne supercharger in, and the idea makes sense. Superchargers attach to the engine and get power from the crankshaft. As they pull air in, they compress it and send it through to the engine, feeding it more air than it could pull in on its own. In turn, this allows the engine to burn more fuel, and to do it more effectively, transferring that increased fuel consumption into raw horsepower. Once you install a Powerdyne BD-11A, or any other compatible model, you begin to see results right away. If your existing supercharger is not holding up to its end of the bargain anymore, you can find the parts you need to get it back to fighting form again. With the vast inventory on eBay, you can find all the Powerdyne performance parts you need to get your car performing like a champ again.
