Guys,
Before anyone gets panicked and tears their engine down, let's get a good hold on the numbers here.
First of all, Druck means Pressure in German, so Druck Pressure is redundant usage..
The Druck gauges are in bar, 1 bar = 1 atmosphere at sea level, or about 14.7 psi
I think the gauges labelled Pressure are all calibrated in PSI increments of 10 psi per line - NOT THE SAME THING as 1 bar!!!
The rule of thumb, going way back to something writtten by BA in the good old days, was "about 10 psi per 1000 rpm" as a good minimum oil pressure for a warmed up 911 engine.
The pressure should bypass at about 60 to 70 psi some where, if it is not, that's a problem too.
So, to close 1 bar per 1000 rpm would be on the high side of expectations, not an average reading...
