HV oil pump vs Stock oil pan

Well, you know, it's been repeated for decades that it was good for a friction reduction and a few extra HP. Who was to argue until some dyno proof? Used to be few had access to a dyno. Now, there are some who have them in their back yard shops. I know somebody who has one. lol

For the NASCAR and F1 crews the couple of HP might be an advantage, but street engines we would never notice the difference. Possibly a bit of noise. Those teams spend fortunes looking for any advantage for that winning edge. If there is anything there, they will know. I expect their pistons have 0 offset.
