Most car purchases are made by people assessing factors such as price, power and performance. In fact, quite a few people purchase cars and then go about tinkering with its engine in order to make it even more powerful. There are plenty of ways in which a normal engine can be made even bigger in terms of performance. And one way is to go in for something known as superchargers. You can certainly look for ways and means to improve engine performance when you browse through the products and parts that are available on websites like tire rack. A supercharger basically compresses the air that flows into the engine. And it compresses it to such an extent that it takes it above atmospheric pressure.

Though turbochargers work on the same principle, they are built differently from superchargers. A supercharger will ensure that the engine is able to take in more air and this gives the boost that is needed as far as the performance of the engine is concerned. A supercharger will also take its power from the crankshaft. But a turbocharger on the other hand, harnesses the exhaust gases to do its work. Depending on the model of supercharger that you go in for, it can work anywhere between 50,000 to 65,000 rotations per minute.
