If you have 15 PSI HOT at 850 RPM idling, NO ISSUE!
The questions to ask is:
"What is the pressure at 2,500 RPM?" If its at 25+ PSI no issues.
"At 4,500 RPM?" 45+ PSI no issues.
"At 6,500 RPM?" If LESS than 65 PSI, then issues.
I think I am OK through the mid range. If it would be making 65 psi at 6500 rpm it may barely get there. To play it safe I have the rev limiter set at 6200 rpm.
