Well if you're comfortable with <50psi @ 7000rpm then knock yourself out. Your UOAs, as you claim, support your decision while simultaneously nullifying your claim of 10psi/1000rpm which your car, with 5w-30, is
nowhere near..
But I can dig it. You're doing the analysis and data doesn't lie. However, when it comes time to tear down, I'm looking forward to peak at those bearings.
