This is where forced induction comes into play as turbocharger and supercharger kits will increase the mass flow rate of air into an engine. However, when picking a forced induction kit, you need to ask yourself one question; "at what PSI can I meet the required mass flow rate of air to reach my goal for XYZ rwhp?" More often than not, stock rotating assemblies will be the limiting factor in reaching your horsepower goals. The additional PSI will raise your peak cylinder pressures which not only means added compressive force on your pistons, but increased cylinder temperatures which leads to detonation.
