Brad,
Imo, the cooler doesn’t negatively affect the system from a starvation perspective. The coolers capacity and flow restrictions are fixed and compensated for.
Yes I track the car and I would say it helps alot but doesn’t “fix” the problem completely. In long turns at high rpm the
oil hangs in the valley, heads and the pump will suck the pick-up area dry, that’s when your accumulator volume come to the rescue.
I think the only real fix (albeit expensive) is a dry sump. I am putting one on my new motor.
