Help! High pressure at the Dyno

Hot versus cold really matters. 100 PSI with 40 wt. oil in a cold engine @ 3000 RPM might be fine, if it drops to 50 psi when hot. 100 PSI at 3000 RPM when hot is too high, you risk blowing the filter off the car and just as importantly you are giving away HP by moving that much oil.

10 PSI per 1000 is plenty.
