Forced induction, especially supercharging, is a popular means of delivering more air into an engine to increase its performance. The supercharger, or blower, was developed long before the motor car. When the Roots brothers in the USA unsuccessfully designed a bi-rotor gear pump for their water mill, they instead discovered it could pump large volumes of air, which was perfect for feeding a foundry furnace. Their first patented blower was registered in 1860 and they had filed 16 more patents by 1884.
When it comes to fitting a supercharger to an engine, the forced induction helps to deliver more air into it and when this is mixed with fuel, it helps to increase performance. Superchargers are a sort of air pump, and they are usually belt driven, taking their power…
