Oil Cooler - Rear Trunk, How I did it. Options

[MAD914]

First off, I wanted to say a big "thanks" to everyone who takes the time to post stuff. I've solved a lot of problems by searching the site. I've mainly been lurking and working, but I thought I'd do some posting of my own to solicit some opinions before firing up the engine. Please be gentle in case I've screwed this up deluxe.

After seeing what had come before me, I wanted to mount the oil cooler so that it would have cool air from the top of the car, instead of hot air from the bottom of the car. I wanted to take advantage of the same "roof-suck" effect that theoretically draws air into the engine compartment. The downside is, I have to sacrifice the rear trunk. No big deal really - I'm not going cross-country in the car.

Anyway, here is what I came up with:



I'm using a Canton filter that's mounted in the engine compartment where the battery tray used to be:




As for the oiling system, I mounted a Setrab dual-fan cooler in the rear trunk, and I'm using a 2-quart cable-actuated Accusump. I wanted the cooler to have cool air from the top of the car instead of the hot air from under the car, so I made holes in the trunk wall to the engine compartment. I've also installed a 180-degree thermostat (the fans turn on at 190 degrees). The lines from/to the engine itself are AN-8, but the system plumbing is all AN-10 to add volume and reduce flow resistance. The canister filter is positioned so the oil enters from the side, and air is purged out the top. Likewise, the cooler fills from the bottom so air is purged out the top as the oil rises up the slope of the trunk. Check valves are installed to stop oil drain-back into the engine, and to prevent the discharge from the Accusump from going “backwards” through the cooler and filter.




Here's how I laid out the installation of the cooler:



And the rough placement:



I'm hoping this might help someone, and I'd also like to hear any words of warning from folks who know more than I do (it's a large demographic).

Thanks!

Do you plan on running this car at the track? I assume so with the accusump that you installed. I bet for the street you'll be fine, though.
I have a very similar engine (so does four blades) and are cars ran fine with the rear cooler till we tracked them.
I spent a lot of energy trying to make a rear cooler work. The simple fact is that the clean air up front is a different world. I actually got to thrash my car, lap after lap, without looking at the damn temp gauge.
Now, I didn't do mine like yours. I bet your works better. Cant wait to see some data.
Here's my thread from my oil cooler fiasco.

This is also brant's advice for the track.
That is why my foglamp vents now house dual oil coolers
