The only factory pressure spec I'm aware of is min. 7.3 psi @ idle and 73 psi @ 6000 RPM at 186 F oil temp. Seems quite a leap to think 270 F temps on a road course were part of the considerations for setting up the oiling system on a $25k car. Especially considering the factory 0w20 oil pressure/rpm ratio pretty much follows the 10psi/1000 rpm rule of thumb for the range of oil temps (max ~230-240F) that would be seen on public roads.
