82 sc oil psi?

[porsche930dude]

Today i had a problem with my oil pressure sender. The guage was not reading so i pulled into a lot and inspected all possibilities. After my brother came with a mechanical oil psi guage we plumbed it in where the sender goes. It had pressure thank god! I had been driving for 5-10 minutes with 0 psi before i realized it. So we went around to various auto parts stores looking for a new sender. No one had it in stock of corse and the ones that could get it were rediculously expensive.
So we went to the junk yard where i was headed in the first place and got one off of an isuzu i think and it worked. I Thought it read kind of low just below 2 bar cold at idle and below 1 bar at warmup not enough even to register well on the guage. So i cleaned out the original one once we got home and reinstalled it and it reads the same thing. It only goes up to 3 bar or so at 6k rpm which seems kind of low. I dont recall what it usto read. Im just wondering what its suposed to be at idle and different rpms? It seems like it was between 2 and 4 bar before but i cant be sure

My 82sc with 202k miles runs about 1 bar over the rpm up to 3,000. At 4,000 rpm and up it's between 4 and 5. About 1 bar a idle.
I've heard minimum is about 1 bar per thousand rpm.

I thought thats what it should be so i cleaned it again better this time and it seems to be back to that. It was just above 2 bar at idle and cold. I didnt warm it up but i think its pretty much fixed. Thanks for the info
