I would say 50 psi is probably fine on a 200-250 hp car and 60 psi up to 300 hp but after that it should be higher.
A turbo car produces torque much sooner so the demand for oil pressure needs to happen earlier and from what I've seen with this oil pump the pressure increases linearly when the oil is hot (cold the pressure is fine).
I do go into more technical detail here if any of you are interested to see what we are working with.

For now I've backed off my power and I'm testing a few things. I will tell you that the oil port at the top of the block (where the AC is) has less oil pressure. Guess what though? That's your crank and rod bearing feed!!!!!!

I think its critical for people like yourself to be sharing data because you are at the extreme end of the limits. Based on what I have seen so far, even with conservative power levels, I just watch how the oil pressure has such a massive swing from high, medium low the hotter that oil gets.
I start seeing 60-65 PSI when oil is hitting 220F near 7200RPM and its worries me. However I have two UOA with zero wear material after track time so I think oil pressure is only one piece of the data.

This is our end goal. Hopefully as people start posting their data we can get a good feel for a baseline and what effect mods such as superchargers, turbos, oil coolers, ect have on pressures.

I am going to try and start posting my stuff this next week.
Thanks for starting thread.
