First, I'm not telling you to do anything. I just want to add an observation here.
I had a friend that was running NHRA ProStock. BB GM.
It was dry sump, pre-heated oil, etc.
At the green light the pressure would be 100psi. Coming back into the pits it would be like yours, under 10.
That was stright weight racing oil.
The feeling was that was normal and the 1000horses just ate it up.
Sounds like you have a similar scenario.
