Oil Pressure Question...Is this normal?

[Mike92GT]

I put a new DSS Pro Bullet 306 in my car a few months ago. It's runs great so far, but ever since I put it in I've been concerned about the oil pressure. I'm using a standard volume Melling pump, Moroso 7 qt pan, and 10w-40 oil. At cold start-up I'm seeing about 55-60 psi. At hot idle I'm getting about 25 psi. When hot, max psi is about 50. Guage is an Autometer electric. I am going to try putting a mechanical on it, but I'm pretty sure the guage is accurate. I'm starting to wonder because I just put a CHP 306 in a buddy's car and it reads 75 psi cold with the same oil pump and same electric guage. What kind of readings do you guys get? Maybe the DSS is built a little loose? They recommend Shell 15w-40, so I might try that.

Run the oil they say to. That isn't by any means bad oil pressure though. Your oil pressure is fine don't worry about it. If you have concerns though contact the engine builder and run the numbers by them.

I asked them about the numbers a while back. I think I'm still within the normal range, but I'm on the very low end of the spectrum. I'm gonna switch to the 15w-40 on my next oil change

Anyone else have some oil pressure numbers that I can compare mine to? I'm just curious what kind of pressure other people are getting. I would feel a lot better if I was getting more like 60 psi at WOT instead of 50 psi.
