    A spoiler is a structure built into the body of car, usually on the back of the car behind the rear window, which is designed to reduce wind resistance by disrupting inefficient airflow. The faster a car drives, the more it must cut through the wind, and the more air resistance the car experiences. Generally the more surface area that is exposed to the wind, the more drag the car will generate, meaning the added surface area of the spoiler adds some drag. On the other hand, a spoiler diffuses airflow in such a way that drag is reduced on other areas of the car, resulting in an overall reduction in drag and increase in aerodynamic efficiency.

turbocharger
supercharger



 way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. Adding a supercharger is a great way to achieve forced air induction. In this article, we'll explain what superchargers are, how they work and how they compare to turbochargers.
A supercharger is any device that pressurizes the air intake to above atmospheric pressure. Both superchargers and turbochargers do this. In fact, the term "turbocharger" is a shortened version of "turbo-supercharger," its official name.
The difference between the two d­evices is their source of energy. Turbochargers are powered by the mass-flow of exhaust gases driving a turbine. Superchargers are powered mechanically by belt- or chain-drive from the engine's crankshaft.
