What is Forced Induction?

  • An engine need 3 basic things to work air, fuel and ignition source. The power that an internal combustion engine can produce is really limited to how much air that you can feed the engine. Since the birth of the engine this has been a problem especially when trying to use an engine in places where the oxygen in the air is very thin such as high altitude.  The solution how to add more air into an engine is solved with a process called forced induction. Various forms of superchargers are used in the process of delivering compressed air into the intake of an engine which is called boost.

  • To match the power output of a supercharged engine a non-supercharged engine or naturally aspirated engine would have to run at higher revolutions per minute or RPMS. This would have a negative effect on the efficiency of the engine

  • The purpose of superchargers is to increase the power output without increasing the engines speed, thus greatly increasing the efficiency of the engine by using significantly less fuel. With supercharging a smaller lighter engine can be used to produce the same if not more power than an engine with significantly larger displacement. Although there is a down side in that more expensive higher strength materials need to be used to withstand the added pressures of increased forces placed upon the engine

Ideal Gas Law

​(P1V1) = (P2V2)
Engine Size in liters (V2 )=5.7L
Normal air pressure (P1)=14psi
Supercharged Air pressure(normal +supercharged) (P2)=14psi+10psi
New Air volume =(V1)
The new air volume with supercharging is a massive 9.77L!
