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...........

I'm using two isolator mounts from these areas to the front cooler flange and using one large isolator under the cooler. I needed to fab a bracket under the cooler for the isolator to mount to. I used a piece of the scrap I cut out of the fender well (outlets) and bent it up to provide a level mounting point under the cooler.

Used a piece of billet aluminum and made a mounting point for the cooler itself. Two recessed machine screws from each side of the cooler flange and the isolator threads into the chunk o' billet.

Once the mounting was squared away, it's on to the duct work. Started out with a rather large chuck of foam from a craft store.

20 minutes with a hacksaw blade and some 36 grit, it started taking shape..........

I had to hot glue an additional chunk to this one to get the size I needed. Then it was on to the front (or inlet) duct. Once again out come the blade and sand paper.

All shaping/fitting done and ready for disassembly and a day of fiberglassing.

You guys bored of the pics yet?

The foam pieces are just junk sacrificial plugs to be glassed over and then torn to pieces. I hope to get them glassed tomorrow, if so I'll post the final product pics. I plan to glass a flange around all the areas where the duct meets the cooler and the body for mouting/sealing purposes.

Yeah.....I want to be able to put the factory false floor back in (althought cut out around my space saver spare). I strived to keep everthing under the area for the floor board.

Question/Concern:

With a GT shroud they made the exit hole twice as large as the input (expanded hot air outlet). Did you look into that?

That's a seriously trick install. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Food for thought . (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) Why not somehow vent it out through the trunk lid infront of the windshield instead of into the wheel area ? Why add more heat to the tire/brake area . Wouldn't that be counter productive ? (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

At least through the top would give you a side benefit of having warm air possibly being blown onto the windshield acting like a defroster/defogger which in the colder climates would be a plus . (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif)

The way you are doing this seems to be well thought out and a damn good idea in its own right. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/clap56.gif)

I have about 35 % larger outlet than inlet. I would've liked to get the magic 50%, but it would've been a stretch. I saw PMS using just 2 - 4" hoses for outlets and he swears he never gets overheating probs. The wheelwell is supposedly a better low pressure zone ( based on hearsay (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) )

I will be using 2 small (3.5 ") fans on the back side of the cooler just to safeguard against traffic jams. They will fit in the oulet plenum on the rear of the cooler. Maybe unnecessary, but easier now than later!

The cowl area immediately in front of the windshield is a high-pressure area. Air won't flow to there very easily. The wheel wells are a low-pressure area, air will flow to there. The air coming out of the cooler is not going to be enough above ambient to make a big difference to the brakes, which see truly hellish temperatures at their "business end". When you're trying to cool something that's 950F, there's not much difference between using 80F air and (average) 90F air...

Near the front of the front hood could work, and might have the side benefit of giving you a little down-force. But that kills almost all of the front trunk for storage.

I'm glad to see you're using GENUINE styrofoam. (IMG:http://www.914world.com/bbs2/html/emoticons/av-943.gif)

That's going to be one of the best oil cooler installs I've seen. I'm also fitting everything under the factory floor, but no spare. Either run-flat tires or AAA only.

but no spare


Check above the thermostat. He's mounted the 'mount' there and a space-saver will sit upright.
