More Rear Mount Oil Cooler Questions, Setrab Setup Options

[BeatNavy]

I'm trying to nail down why I'm having oil cooler issues. Specifically, I've blown two sandwich plate adapter seals in the same place / manner. In addition, during my test drives I wasn't necessarily thrilled with the temp drop I was seeing.

First, I'm running the Setrab oil cooler and Setrab sandwich plate adapter. Anyone else running the Setrab sandwich plate adapter without any issues? I know I'm not the ONLY one, but how many people run this as opposed to something like the Mocal setup?

Second, when I contacted Pegasus Racing to order more seals, I spoke to the tech guy who gave me some food for thought. The most interesting thing was he said the oil cooler needs to be mounted with the inlet and outlet ports facing up, otherwise the cooler won't fill up all the way and you won't get ideal (or any) cooling.

Here's my setup with it angled somewhat down for what I hoped was good airflow: http://www.914world.com/bbs2/index.php?s=&...t&p=2826235

Essentially he says the oil takes "the path of least resistance" which could largely be from the inlet port to the outlet port using few of the cooling rows. I assumed the pressure would fill the cooler, but I can see what he's saying. Any thoughts on that? If that's the case, I really need to completely redo my mounting setup and plumbing.

Yes, you are trapping air in that cooler, flip it around.

In an ideal world, inlet should be at the bottom, outlet at the top, but both at the top will be good too. Initially, as the oil fills the cooler, it will push the air out. In your setup, the air has not way out, unless you had a purge bleeder at the top. Same as purging brakes lines, bleeders are on the top.

Here's my setup; those sharp elbows at the top are not the best, nice sweeping elbow would prevent pressure loss.
