Oil pressure bars (Atari) vs gage pressure

[-Ray-]

What do you get at WOT? Mine has about 45psi at idle but it never seems to get over 55psi at all.

I've seen it as high as 57/58.

The oil pan relief will keep it from going over 55psig.

Thanks for the answers. I was hoping it was the oil pan relief valve but just wanted to see if that was normal pressure or not. I get paranoid about stuff sometimes.

Your cam is too small. ;-)

With my new VMS 1.5 cam/head package installed I am seeing 3 bars cruising, 4ish @ WOT, and anywhere from 0-2 at idle. I don't remember ever really paying attention to it before the install so I'm not sure if it's normal or not.

Yeah, yeah. I have heard that before.

Its the DOD hardware. Before DOD delete I would regularly see below 20 psi oil pressure and it scared the shit out of me but afterwards I hardly ever see below 35-40 psi. And i'm still using 5W30.

As an update, it's not the DOD hardware per se... it's the cam. After changing cams to a non-DOD one, still leaving all of the DOD stuff in, pressure has not dropped below 4 bars, even after hard runs. The stock DOD cam has a split bearing that would supply oil to the AFM stuff, if it had it. I believe that this bearing causes the lower pressure we are seeing. I'm back to 5W30, and very good pressure - with all dod stuff but the original cam.

AFM cam on the right.

yup...that's it.
