Actual Oil Pressure
Actual Oil Pressure
These are the readings I'm getting.
(Yah, I know there's not actually a throttle.)
Hot:
Idle: 25 psi
Just above idle (1000 ish RPM): 40 psi
Mid throttle (2000-3000 RPM): 60 psi
Hard throttle (4000+ RPM): 80-90 psi
Cold:
Idle: 40 psi
Just above idle (1000-1500 RPM): 80 psi
Mid throttle (2000-3000 RPM): 100+ psi
Hard throttle (4000+ RPM): Haven't gone there!
Almost forgot to mention, this is measured through a fitting drilled into the top of the oil filter housing.

Thought y'all might find this interesting. I just installed an Auto Meter mechanical oil pressure gauge in my wagon with a scale of 0-100 psi.

Thats why your numbers are low. I measure mine off center of the filter cap and they read about 10psi higher than what you show hot and way higher than cold. When my engine is under 60*c the oil pressure is always 80-110psi at idle.

I drilled my fitting in the spot shown in the attached photo where the pressure sender is located, not dead center. Was this not the ideal place to put it? (Note: Photo is not my car.)

Low? Those seemed pretty good to me. Forced, the description of your fitting location leaves me a bit confused. Please give more detail.

That is where mine is. Cold idle should go straight to the 7bar relief pressure and stay there until the engine is somewhere around 40-60*c.
