At idle mine is around 50 when the oil is cooler and drops to around 30 when the oil temp gets higher. Mine also jumps considerably higher when getting on it.

Upon cold start it's at 60 psi.
Up to temp at idle mine's at 37-38 psi and add about 10 psi for every 1000 rpm thereafter...

Good rule of thumb to put in the back inner recesses of the mind.
I never saw this amount of psi in my '06. That's why I was wondering if 100 psi for a sustained amout of time would pop a gasket.

The temps are around 195-210 the RPM's I didn't notice, but I was in third and probably around 90ish mph.
The astute wife of my asked me if it should have been that high and when I looked down I took my foot off the gas.
I'll get on it today and see the RPMs

My 08 Z has @ 85 at cold start, on a long trip at 75 MPH the pressure is about 55. Oil temp rarely goes above 185.

I just switched to 15W-50 and while i love it on track... the street pressure (driving to/from the event) is freaking me out... I don't like seeing 90-100 PSI so much
100-150F: ~75 psi at 2000 rpms
150-160F: ~75 psi at 4000 rpms
187F: 82psi at 5800 rpms
Ambient temp: 70-75
So i figure I have a 300hp Z06 now... as i'm afraid to go over 4500 rpms at my normal oil temps (150-160F)
100-150F: ~75 psi at 2000 rpms
150-160F: ~75 psi at 4000 rpms
187F: 82psi at 5800 rpms
Ambient temp: 70-75

Same here, cold start 60 psi, but as temps warm up goes down to 35-40 psi idle.
Just depends on temp and weight of oil, obviously higher weight will give higher pressure

At a cold start I am at about 70psi at idle and then it settles to 60psi pretty quickly. It goes up to almost 70 psi at 2,000 - 3000 rpms until the car is warmed up. Once fully warmed up with oil temps around 180 I am at 26-30psi at idle and around 52 psi at cruising speeds.

Okay
Using AMSoil 10w 30.
I tried yesterday to replicate high psi on the highway and couldn't not get the same conditions.
This morning on the way to work;
1st gear
30mph
3500rpm
Oil psi 100

100 psi seems high if at operating temp (175f +-)

Here's what you do. Take your car (filled with 15w50) up north and park it in a parking lot in Fairbanks this winter. Start it up at 4AM without letting it warm up, and just hammer the S@#$ out of it straight away, making sure to bounce off the rev-limiter in every gear before shifting. Let me know if everything works out!

That's kind of irrelevant since the oil filter is on the scavenge side of the oil system. The oil pressure reading is taken in an oil gallery after being pressurized by the oil pump. The oil filter never sees the engine bearing/lifter oil pressure.
