To shift gears, I have a question...
I'm running a hydraulic roller cam. Melling M83 standard vol pump (at the recommendation of some builders who said that the high vol pump can wear down the distributor gear or something to that effect - it's been so long I forget the exact advice.
I've heard some people say similar things about
oil pressure and boost from a supercharger - pressure is only a measure of pressure, and in this case, it is back-pressure. You have to measure volume to see what's actually flowing (i.e. - 8lbs of boost on heads that flow 200cfm is better than 10lbs of boost on heads that flow 15).
Bottom line, I'm seeing pressure shoot right to 60-65 psi on a cold start, then as the
oil gets hot, it drops to about 30 at idle. On take-off, it pops up to about 45-55 psi and stays there pretty much from 2K-6K rpm. I'm not running over 6K but am considering changing our chip to 6500. I'll never run over that.
I've heard that as long as you have
oil pressure (a reasonable amount, I'm not talking about 10-20psi), you're good to go.
Am I risking starvation only having 45-55psi at 6K rpm?
