Oil cooler..........round two, AKA fun with foam! Options

[East coaster]

So after a little brainstorming on an oil cooler layout, I figured I better actually do it.

Started out by figuring out the mounting of the cooler itself. It's a very large (4 x 24 fin area) and I think a good fit for a 3.6 since it doesn't have an engine mounted cooler. I started by cutting sections out of the front support tray for clearance and then re-boxing the area to keep the shelf rigid and serve as a mounting point for the front of the cooler.

Here's a pic of the cut outs...........

Anderson says quite a lot.
He says the 964/993 oil pump moves 67 liters per minute
on the pressure side & 1.8 times that much on the scavenge side. I can't remember the exact specifics on the 76-88 pump
but I think it was in the mid 50s per minute on the pressure side.

He also talks about restrictions in the Aux cooler side causing
the oil pump fail. Too small lines & restrictive oil coolers, yada.
The scavenge side is unregulated...pressure wise. Restrictions
or cold oil cause the pump to work harder.....it is almost a positive displacement pump, me thinks. As restrictions rise, it just keeps pumping
its 67 liters by raising the pressure. When that gets beyond its capabilities, it cavatates. The voids caused by the cavatation can allow the gears
to become exposed to each other...not to mention the drive shaft shocks. Bad shit.

If you have an aux thermostat with a pressure relief valve, the oil can by pass the cooler & be pushed thru the filter (with it's own pressure relief valve) into the tank.....no harm , no foul.

If you don't have either of these safety features (cheep filter & thermo)in your scavenge loop, that's your problem, not mine.

I'm done with this subject....move along, nothing to see here folks.
