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"... |

Another possibility with the VDO being inaccurate is poor/shifting grounds.
You can isolate the VDO from the car chassis and then run a dedicated ground from the sensor to the gauge. A regulated power supply is very simple. You can actually install one component like a LM7812 that will output 12.0V as long as the input is ~12.8 or higher. I put a mechanical oil pressure gauge in with the VDO and they give the same answer, but I dont have a lot of time on the system. I would also like to see a detailed diagram of your oil setup. I know it was discussed over in the paddock, but I never did get a good diagram. Although I did start working on some new oil diagrams that you commented on and even pulled out a spare case so I can inspect it. I am still installing the front dual oil coolers. For right now I will just use a filter sandwich plate, but want to do a sump upgrade after that. |
