Concept of Forced inductions came from the need of some extra power to stand out in the crowd . Two general type of sports cars we get these days include : A turbocharger A Supercharger Let me give you an overview about the working of these two. Turbocharger is basically a turbine which has a rotar blades that gets their movement from the exhaust gases from the car's exhuast. The turbine then turns the Compressor and then compressed air from compressor goes into the Intercooler to cool it down and then introduce it to the intake manifold. Since the Air is compressed ( high pressure) It makes the ignition quicker and more fuel is burn ( means more efficiency for the amount of fuel burnt) hence more power.Turbo chargers Do CUT OFF at certain limits Supercharger is just a compressor driven by the drive shaft of the engine and its always working because of that reason. Drive shaft turns the supercharger via BELT/Chain depending on the car setup and hence it introduces the compressed air into the intake manifold and resulting in improved ignitions and efficiency for the same amount of fuel. Now My question is. What do you prefer?
