Normal Oil Pressure?

[Scott_Higashi@necelam.com]

Hi All,

I just installed an Autometer oil pressure gauge (first one delivered had
an idle needle at 25 psi! - this is the replacement) and had some
questions.

Here's the setup:

New Nissan Oil Filter
4 qts of Mobil 1 10W-30
Freshly installed JDM motor

Idle cold = ~60 psi
Idle warm = 22 psi
2000 RPM = 51 psi
3000 RPM = 60 psi
4000 RPM = 65 psi
5000 RPM = 68 psi

So, it seems high to me, but is it?  Where is the pressure blowoff supposed
to kick in?  It seems like somewhere around 65 - 70 psi on my particular
motor, but is that normal?  I've heard the 10 psi for each 1000 RPM rule of
thumb, but this seems a bit out of whack...

Thanks,

-Scott
