Just an FYI, the 2.5L V6 running at 7000 RPMs, uses ~306CFM at 1 atmosphere. This doesn't take into account the vacuum that is created with "restrictive" intake parts and valvetrain.
To be able to build up 10 PSI in front of this 306CFM air pump, you would need to have a comressor that can produce 10PSI at ~650CFM.
If this figure is WAY off, please forgive me. This was done with experimenting with a precision digital manometer with the battery going out, and a calulator made by Microsoft.
