I agree! Even if it did cost a few extra HP, the oil pump ain't the place to look for it. "OOO lemmie run a stock volume oil pump cause an HV pump takes too much power oooo"
Engine Masters actually shuts down the myth that it takes more HP to run an HV pump. Proved it on the dyno, no difference in HP standard pump vs HV.
I updated my roller 340 with an HV pump this last winter and my hot idle oil pressure went from 20 psi to 35 psi remains 65 psi at cruz'n speed.
