The main function of turbocharging is to increase the engine air intake, thus increasing the power and torque of the engine and making the car more powerful. When an engine is fitted with a turbocharger, its maximum power can be increased by 40% or more compared to when it is not fitted with a supercharger. Generally, the engine in a racing car is equipped with a turbocharger, its role is to make the car have more power. The car's power is derived from the engine, the engine is relying on fuel combustion in the cylinder to produce power, because the input fuel is limited, therefore, the power generated by the engine will also receive a limit. The turbocharger, on the other hand, is a mechanical device that can increase the output power with the same engine efficiency.
