Hi
Really a shame that there is not more DATA to support this topic when it is readily available to log from the N55...
Anywho...went to the track on Cup2s today as saw pressure dropping to
22psi during
straight line braking!!! I have done quite a few trackdays before but never really concerned me about oil pressure. I do now! I'll definitely be looking into the M2/3/4 oil pump swap before I kill the engine.
