2G oil pressure values at idle and WOT?

[GstRacer]

getting an new greddy 60mm oil pressure gauge with a warining an peak lights an it reads in BAR witch is 14.7 psi but what should the idle pressure be and what should the pressure be at like 3000 rpm and what should it be at wot?? also what should i set the warining to light too?? probably higher then idle pressure right ??

1bar = 14.5psi, not 14.7

Warm idle, oil pres should be around 15-20, and from about 3k on 70+

One problem with 7bolts is *theory of course* that the lifters open under idle, stealing away needed oil pressure from the bearings.

actually its 14.50377 but whos keeping track.

anyway i was wondering this also. im rebuilding an engine and wondering what the values should be on brand new oil pump, with external oil cooler etc.

What in the hell is this?

Everyone disregard, we locked his cage back up. Go on with your business.

Oil pressure at stock idle range should be ~11psi. It can be slightly more BUT not less than 11psi.

I can only assume that he's talking about the oil squirters opening up since they are run off the main bearing oil pathways.

but I don't think we'll over know

My autometer shows me large increments but is near the bottom of the guage at an 800rpm idle and hovers around 55-60 around town. On the highway its more in the 75psi range, wot can peg the guage depending on temperature.

 

[GstRacer]

well got the gauge in and it read like .2 or .3 bar at idle then it reads like 3 to 3.5 to 4bar at 3000 rpm and i havent hit it to wot yet is there a problem i had Pruven performance put the guage in so i would have thought they would have told me if there was a prob i'
m woried becuase the first post says 15-20 psi at idle and 80 at highway speeds and i'm not reading close to that and my stock gauge still works and reads normal please help

i had AP Physics in highschool and i specifically remember that 1 bar/atmosphere= 14.7psi. You all may argue with me but im just stating a fact, idk

actually 1 bar = 0.9869233 atm

which rounds out to 1 atm. most just say 1 bar = 1 atm because of rounding and they are close


Oh, and I have a program called Convert that will convert just about any measurements. hence where im getting this stuff

also, most say speed of light is 3x10^8.... when actually its 2.99xxx x 10^8. i forget the actual amount but they are rounding. rounding not always good.

anyway. if someone can hostthis program i have then maybe they can put it up for others. i got it from a friend, or you may be able to download it on the net somewhere.

1 bar =
75.00617 cm of Hg =
1000000 dyne/cm^2 =
29.52999 in of Hg =
1.019716 kg/cm^2 =
10197.16 kg/m^2 =
100 kpa =
0.1 Mpa =
1000000 microbar =
1000 milibar =
750.0617 mm of Hg =
100000 Pa =
2088.543 lbm/ft^2 =
14.50377 psi =
1.044272 ton/ft^2 =
0.007251887 ton/in^2 =
750.0617 torr

That should cover most pressure values anyone would ever use for anything.

Isn't it 1.0b = ~14.5psi, and 1.0atm = ~14.7psi?

[Eagle 5]

after some converting (not using program, at work currently)

1atm = 14.695944 psi

so ya, about 14.7 psi.

i do all my convertions with google, its quick and easy:
like:

or
