I'm trying to find the correct oil pressure on a YB Cosworth engine with a HP Oil pump.

I've installed an innovate gauge and I saw the following readings:
Engine Cold: 5,55bar (about 80psi)
Engine's optimum temperature (4wd 82C)
idle(aprox 1000rpm): 2,2 to 2,6 bar (32-38psi)
2000rpm: 4 bar (58psi)
3000+ rpm: 4,5-5 bar (65-72psi)
Engine oil: Motul V300 10/40
Ambient Temperature 15+C

Is it OK?
Anyone else with readings on a HighPressure oil pump on a YB Cosworth???

Thank you!!!!

I get similar readings with a standard pump and Millers Nanodrive 10W/50.

Your engine temp is too cool though. Have you got he wrong thermostat in ?

I have the 4wd thermostat 82C its from MSD
Gauge temp seems that it works ok!
I do not see low temps on my cooling system.
You think that for High Pressure Oil pump readings are OK???

I,m no expert but I would say 35psi at hot idle was absolutely fine.

from where did you get the pump..press.looks fine

From I've read during my research of this you are getting good pressure. However is 10/40 actually recommended for a cosworth? Thought you'd need something thicker while it's hot .

There is nothing wrong with running the cooler temp thermostat, as the cossy engines will get hot. The oil pressure readings also seem fine. Nothing to worry about in my opinion.

I've bought the HP Oil pump from Burton.
I thought that I should have up to 6 bar oil pressure with my engine cold.


Thank you for your opinions!!!!!!!!!!
