I have a GReddy gauge(forgot what it reads in) that I *believe* reads in kg/cm^2. What should it be at idle warmed up, cruising at 3000rpms, and WOT runs to redline? Thanks.

 

30psi = 2.1 kg/cm^2

so 2.1 at idle 4.2 running

 

The conversion fro kg/cm^2 is 14.2 to convert to psi.
If it's bar, the conversion is 14.5 - watch out for the units!

Like Scott said, as Canadians our oil pressure gauge is in metric from the factory so were used to looking at it this way. Just over 2kg/cm idle, and it won't get up to the full pressure of 4.2-4.5 until the revs are up.

 

Ok, I looked at mine this morning and it is in kg/cm^2. I get 6 at cold start up and it goes down to 2 at idle and 4-5 during acceleration. I take it thats normal.

 

That sounds about right!
