I've always heard 10 pounds per 1,000 RPM. Don't know if that's just some old wives tale or not. I do know that I had an 8ba in a '40 big truck and when it got warm it had 10 pounds or less at warm idle. Didn't have it long enough to really know how the low idle pressure affected engine life but it made me nervous looking at the gauge at warm idle.
