Yes- At 4000 rmp she is in the 60s. The analog dial is useless

Drove her for an hour this AM

Why do you say that? Seems like it's inaccurate or poorly chosen scale?

Because it stops at 50.

I have it in my little digital screen which works great

Hmm, I thought the Euro ones go to 5 Bar (around 75 psi). Are you sure the US ones stop at 50 psi?

It goes to 5 bar. Are you saying each bar is 15?? If so, thanks

1 bar = 14.5 psi or thereabouts

Recognizing this is a .2 and a different motor... my .1 has pressure similar. Took to dealer and they claim normal

Was told by Porsche techs that the new oil pump provides increased pressure on demand, unlike 991.1. I am seeing [email protected] rpm.

That sounds good - confirms what I suspected (after 4,000 rpm the oil pressure does not continue to rise at the same rate, if at all).

At idle (800rpm) - 25psi
At 4000 rpm - 66psi
At 6500 rpm - 70psi
At redline - 72psi (far right of the red area)

I changed my oil to 5W50 which might make a difference in PSI. Oil level has always been green and I haven’t needed to add any oil.

I looked at a video I took a few hundred miles ago and PSI levels are pretty much consistent +/- 3psi. The discrepancy has to do with throttle position it seems. Going 0-redline but keeping an eye at 6500 rpm for example reads 62psi, no throttle letting it coast down at 6500 reads 68psi, and light throttle holding 6500 reads 70psi. Moral of the story, yes it is normal for PSI to read this high and even the manual says PSI varies based on oil temp and throttle response

I had posted this when I got my car, but in my .2 gt3 oil psi is at 50 at 2000 rpm and reaches 60 at 2500rpm. It rises slowly after that. This is when the engine is at operating temps above 190 F.

I think this goes along the fact of that the oiling takes less effort in the new redesigned engine.

PS: forgot tom mention that the analog dial is relatively inaccurate as it has been mention in the posts above. The reading I mentioned are with the digital scale.

Same with me; I noticed around the same range driving on the highway. It should be normal; I’m not worried about it.

Totally normal. Just like someone else said, Porsche just doesn't adjust the analog gauge for the GT cars. Must be too expensive lol...

Same thing for the fuel gauge if you have an extended tank. Doesn't read properly.
