Do you have any test data, etc that could tell me ....
What's the oil volume vs. RPM curve look like on the stock pump versus these hi-performance pumps?
Also, what is the stock oil pump relief pressure setting and the relief pressure setting on these hi-performance pumps?

Humm ... 32 psi seems low since I see 70~75 psi on the oil pressure gauge at high RPM on my stock LS6. Maybe that is when it just starts to crack open, but regulates max oil pressure to around 75 psi (?).

High volume oil pumps are useful for engines that require more volume (not necessarily with more pressure) - maybe due to adding a turbo that has oiling needs, etc. The only way to get more high RPM volume on a stock oiling system is to increase the relief pressure along with a higher volume pump. Higher volume pumps also give you more volume and pressure between idle and the pressure relief point at higher RPM ... but once the pump hits pressure relief, then that will determine the actual volume of oil going down the engine's oiling circuit no matter how big the oil pump is.

ARE has LS1/LS6 dry sump pans. Scavenge pumps mount where the AC compressor goes and is driven by the same belt. The pressure pump in the engine stays. Also a dry sump tank would need to be mounted. On our LS7 F-body we built years ago we put the tank where the battery was and relocated the battery to the back.
