So true. Many that contribute here have much more than I have with these Porsche engines. My start with Porsche was with the 962C race engine. Pretty late start compared to others here.
I have been doing this along time. I was very lucky and got to learn from some of the best ever. What was common from all I learnt from was an engine can never have enough Oil and Water pump.
Volume isn't the torque robber. Pressure is. Maybe you misunderstand what we are looking at.

Perhaps your understanding of fluid dynamics isn't what you think it is.
Ultimately, pressure is the relationship between volume and ventilation.
In the most efficient system, the volume should only be slightly higher than necessary to fulfill oil demands and create a minimal amount of ventilation.
Ventilation in this case is a pressure regulator/check valve.
Spinning a pump that creates a higher than necessary volume will rob horse power.
