However it would be excellent for those running N/A cars and probably great for those running thicker oil in cooler climates. I Dont know how I feel running two oil coolers/warmers though its just too much crap on this car for a street setup.

Just wait until it's down to 120 or less until you drive if you are concerned but honestly from all the years we've been building and racing these boxer engines it's normal. We even strive for 90+ psi under normal driving conditions because it means well have 80+ hard driving and 75+ while racing.
If you're not racing in the colder months I would still strive for 60+ psi with a heavier oil and block your oil cooler temporarily if need be. Viscosity is a number based on oil temp so you have to account for that if operating at higher thsn the rated 100c.

I really value your opinion obviously, I would have never been testing this without your threads. In honesty I wont run the car in winter anymore because its already a rust bucket after two years. But I think after this discussion I'd just run two oils going forward. IN winter for sub zero starts stick with 0w20. In summer track months go to 40w. 10w30 redline is a thick oil and at 245F oil temps, pressures go terminal.
The bigger issue is I dont think people who track these cars with FI monitor this at all. My setup is ultra conservative compared to most.
