As fan as pressures go... I'm running a decent used timing cover, bulltears melling oil pump gears, and their external filter endplate without the little steel sandwich they sell to go between the pump and endplate. I have half inch ID copper tubing in straight runs between the filter plate included in bulltears kit. I use Delo 10w30 part synthetic with a Napa platinum filter.
At cold idle, I see 40-60 psi depending on external temperatures.
Cold cruise I see a consistent 60.
Hot idle is mid to low 40's.
Hot cruise is 40-50.
Hot and above 3000 rpm I see 50-60 pounds.
Heat soaked, running it hard for hours on a 98 degree day with the temp gauge the highest I've seen it, I had it down to the low 30's at idle. Oil temperature at the filter that day was 212.
I could go to a thicker oil and get better pressures when heat soaked, but thicker oil won't flow as well. Greater pressures also put more stress on the distributor gear.
