I'm running the CB performance dry sump pump and am attempting to get a bit more pressure at hot idle. I'm considering addressing two potential issues:
Primary Concern: I used Loctite 518 AND the gasket between the cover and the pressure side of the pump. 518 is a gasket replacement and NOT a gasket enhancer. Anybody care to guess if I managed to increase the cover to gear clearance a bit by using 518 and the gasket on the front cover? Secondary Concern: The last 3 feet of my supply line necks down from -12AN to a T and then -10AN. Not likely in my mind to cause a hot idle issue (cold idle is 40PSI), but thought I'd mention it. Idle pressure is almost exactly 10PSI at 185F and 1000RPM. I'm using Brad Penn 20w-50. BTW - both motors appear to have water vapor coming out of the breathers with Brad Penn. I've heard others having this "issue" too. Is it an issue? I'm considering trying Jake's "Snake Oil"... |
