True, but wouldn't the output from a centrifugal supercharger or a turbo
be much more turbulent than incoming air in a NA system?

Also, let's say that your peak amount of boost is generated at 6000rpm.
Would you want to tune your intake runners for maximum ram effect at
6000rpm or would you rather tune it for 2500rpm to help out low-end torque
as much as possible?

Thanks,
