In theory 3 inch pipe will flow the same cbf of air at 5 psi that it will at 20 psi the change is the density of the air flowing thought the pipe. Now the base atmospheric air cbf numbers are no long on the same plane as the 20 psi number unless you let the pipe fill a space (like a big room so it not compressed anymore )
But at this point it has nothing to do with building hp or a engine's air flow manners anymore
