So, I hear my 01 2.5RS draws somewhere in the neighborhood of 300 CFM at 1 atm pressure. 1 atm is roughly 14-15 psi, right? So, is it safe to say something like:

300 CFM / 15 psi = 20 CFM required per PSI of pressure,

meaning if I had forced induction of some sort putting out 320 CFM, I would be under 1 PSI of boost? (and 2 PSI for 340 CFM, 3 for 360, etc...)
