With my previous Cobra's (I had three before this one) the
oil pressure was between 40 and 50 psi (driving around). At idle it was lower, about 5 to 10 psi, average maybe 7 psi. It did go up when driving, but not 10 psi per 1000 rpm. It went up going from idle to maybe 2000 rpm and then it was pretty stable. Ofcourse cold psi was higher than warm psi.
From what I have learned: if you have the correct viscosity the psi goes down only a bit ( max 3-5 psi) from cold to warm. It should be between 20 and 80 ( at 80 psi the hoses might burst). My pressure stays pretty constant from 2000 rpm and up.
Just my 2 cent. If I am wrong, someone will correct me.
