What is the max oil pressure i should be comfortable with (under load) on my 3.6L?
I've been reading 993 manuals and posts all over the tinterwebs and all i can say for certain is that the stock 993 gauge seems to max out at 5 bar but according to all the info i found you'll get there already around 3k rpm and then the gauge just sits at max. The reason i'm asking is that i'm using a gauge showing psi instead of bar (with the correct sender for that) and 5 bar should be around 73 psi but my oil pressure is substantially above that under load. I'll idle around 40 psi (sometimes drops to 25-30 when it's really hot) and hit 100 psi as soon as i get above 3k rpm and pretty much stays there. I've seen as much as 110 psi. 100 psi is about 6.9 bar 110 psi is about 7.6 bar Question is, am i about to blow up my engine running these kinds of pressures?
