Limit for reliable power on track?

I'm using Amsoil Dominator 15w-50. I've done 30+ track days in my Camaro with Mobil 1 15w-50 on stock bottom end and that car runs 210F oil trmp on the street and 260-300F on track. Never had a problem. In the Evo, temps are much lower and I'm using a better oil, which I replace every 2 events. That's why I'm not too worried about 240F oil temps, though I think I probably would have higher temps if I ran the car in 100F ambient temps and redline shifted it every lap, which I avoid. I am planning to do Blackstone analysis this year as well to make sure things are healthy.

Your setup looks good to me. I've always run 24-25psi for track tunes. I've used everything from stock turbo and O2 housing, to aftermarket O2 + FP Green. Pump gas, e85, you name it.
my oil gets WAY hotter than yours before I take a cool down lap (Rotella T6 before, 50w VR1 with FP turbo) . Stock oil cooler and radiator (with Evans, as opposed to water).
No problems. You should be fine.
edit: 340whp on stock turbo, 450Whp ever since.

Yeah HPDE with the longer sessions put a lot more heat and stress in the system. Like Dallas said you want to do what you can to get that boost controllable and predictable as well. So it's worth pulling that down to get that solved as opposed to having to pull it down for other reasons IMO.

I finally pulled the ebay O2 housing off, without removing the turbo (yay nickel antiseize used in previous installation), and ported out the passage for wastegate flow. It wasn’t that small, but I mostly removed the internal wall in the housing. Took care of the creep issue.
