so this was the first weekend I tracked my 318 with an oil pressure gauge installed. I've heard you want to maintain about 10psi per 1k RPM (don't know if this is valid at all), but mine certianly does in a straight line, usually is around 50psi after 3k and almost 70 at redline.
But I was a little concerned as I layed it into some long righthanders at Roeblingbling, pressure would start to fall off, and through apex and exit, it'd be maintaining more like 30psi. Running a little overfull helped, I was seeing more like 25 or less before I added another half quart. I started running more of the long corners in 4th just to keep the revs down a bit with such low pressure. Short rights and any left were no problem.
Does anyone know if this is "normal"? I'll ask around, but just wanted to know what you all have heard. Many BMW's have pressure problems when holding a hard right, complicated by the slant of the engine and oil sloshing up the side of the block, I just don't know how low should be considered dangerous.
Any tech info or links would be much appriciated! Conjecture and hearsay will be tolerated. :wink:
