Really makes you hate new cars, doesn't it? Really makes me wish I could buy the shell with no goddamn engine, and put an appropriately over-engineered piece of machinery in there. Still considering that option - more to come soon.

I'd just like to reiterate what I said on the last page and clarify for everyone, because the statement Lee made is correct in this application
by pure coincidence, and his statement is
conceptually incorrect. He made a 4-part statement, and it's wrong to call it correct.

At high rpm and temperature with dropping oil pressure the PRV will be closed.

I color coded it by factual accuracy.
Green = Correct
Red = Wrong
Orange =
Correct in this application, by coincidence, but USUALLY wrong. And will likely become incorrect in this application if pump discharge volume is increased at any given viscosity.
Hope that helps people understand a bit better. Read post #489 for further clarification
