Oil pressure help

On full throttle i have 36psi of oil pressure. I checked oil pick up tube cleared debris checked oil pick up tube clearance from oil pan and it’s good at 1/2 inch from bottom of pan. I have copo oil pressure spring which is the highest spring you can get. I run 15w-40 racing oil from redline or rotelA 15w-40 for cruising. Not sure why my oil pressure is so low please help

Did this problem appear before or after you started using this oil? If you checked the oil supply system then it may be worth changing the oil. Maybe it is worth trying another oil, for example, I have been using Shell Rotella for several years, it maintains oil pressure, there are even comparisons Mobil Delvac vs Shell Rotella Oil Comparison, you should not have any problems with the oil supply system.

How hot was the oil when it's at 36psi at WOT?

For reference, I get about 35-40psi at WOT on a hot track day with my oil temp at about 240-250 degrees.
That's with AMSOIL 5W-30.

WOT has nothing to do with oil pressure, engine RPM does. Your oil pressure should be about 22-30 at idle and max out around 60 psi when the engine is at full temperature, 36 psi oil pressure maximum is not enough.

Are you running that thick ass oil because you were having an oil pressure problem already? 15w, way too thick on startup and these are designed to run 30 weight, unless you have had an engine builder build you an engine. If you aren't getiing more than 36psi throughout your rpm range and you have verified with a manual gauge you probably have some excess bearing clearances.

^^^exactly. These engines are designed to run on 5/30 for proper oiling and flow to all the valve train parts. It could be too thick and doesn't flow properly so the pressure will show low.
