just wired oil pressure gauge in, its a 100psi version, on engine start up the gauge is flat out at 100psi, although this drop when warmed at idle, as soon as i touch throttle it just reads off the gauge, is this normal or does any1 know what it should b roughly reading, i dont know wether i should have fitted a gauge with lets say 150psi on it, nb. i think its had a modified oil pump fitted, will this also affect it?

When warm and driving, my gauge reads 6 bar. This is 87 psi.
On a cold start mine will read over 6 bar.
So bearing in mind that 100 psi is 6.89 bar, then yes it is feasible that your gauge will max out when cold.
I would say that is normal when cold, as my car has reached that sort of figure before.
When warm and idling, mine sits around 3 to 3.5 bar, so that is around 43 to 50 psi for you at tickover warm

Agreed with MaDaSS

I've got a 100psi on mine. Start up reads just a touch over 100 then once warm about 90 - 95 ish. Then when at idle while warm, 45 ish. Rev it and it just acts like a RPM gauge

should be ok with the gauge you have IMHO

yes, had oil temp upto 90 degrees 2day, and at idle pressure was about 45psi, but as b4 when revving, just goes straight upto 100psi, but from what u guys saying seems 2b about right, thx 4 the feedback peeps!
