GT Motorsports: 370Z Supercharger system development

KEVTEX

Intake piping size will affect efficiency. 5psi at the intake manifold will produce the same power when delivered through a 1/2 inch pipe as it would with a three inch pipe. The system using the 1/2 inch pipe would waste a lot of the power produced in forcing enough air through the pipe to yield 5psi at the manifold. Pressure inside the 1/2 inch pipe would be about 36 times higher than the pressure in the 3 inch pipe to deliver the same 5psi at the manifold.
