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.

I have several oddball things going on, like an IGN4-VW coil that starts cutting out after 30-40 minutes. I attribute that to something different/wrong with my engine/car.

I may try adhesive-backed reflective insulation on the underside of my airbox.

Is it the Ignition coil cutting out or do you struggle with sync loss problems due to too high temps at the Crank Pic-Up Sensor?
Do you have a tooth log?

Very confident it's not synch loss; I'm not logging any synch loss at all except when I "burn" with the car running.

Symptoms are stumbles and the AFR momentarily pegs full lean. I replaced the coil with a new one and it briefly got a lot better but it's starting to come back. Usually runs smooth for a half hour, then very light stumbles til about 45 minutes, then very hard stumbles. Died on me yesterday, I had to coast to a stop. Top of the coil was 184F via IR.

I've been told this coil really likes big wires for power and ground, but I'm using AWG14 for both, didn't seem to affect anything.

I'm thinking it's just getting too hot in the location I have it (on top of where the disty was).

We can discuss in your Megasquirt thread, I need some ideas.
