From past threads I know this has been touched upon before. Its been discussed lightly.
Let me ask this basic question.

At temp,...at idle oil pressure should be what on a stock GT,...mine idles at 700 RPM?
At 2000 RPM, at temp, oil pressure should be roughly what?

Car has textbook, conservative pulley and tune.
Thnx


PS,..I will tell you what the RPM's are on my car once we get some posts. I dont want to "lead the witness."

At Start up 75lb

Should settle around 50 over 2000 RPM at 180-200 Degree

Can fall to under 50 after hot runs on track, up canyons or sustained high speeds when at 200+ degrees

Usually at stop lights you can see it dip down or flutter

That's what my gauge shows, although it has never run over 200.

Mine is at 50 at 2000 RPM.
What about hot idle?

Today, on the first drive of the season, the hot idle oil pressure was 35-40 psi. Generally runs about 55-60 at 2,000-2,500 rpm, 75 psi on cold start up.

Thnx guys
Looking at the stock gauge I'd say mine is at 30.

Mine starts up cold at about 65-70 and settles back to 50-55 after it warms up.

Surprisingly enough, my Cobra with a modern reincarnation of a 427 did the same thing.
