Rear Mounted Oil Cooler?, Anyone? Engine type does not matter... Options

[Cracker]

I'm looking to add a second oil cooler at the back of the car/engine compartment...has anyone else mounted coolers in the back? If so, please post pictures and results. This is for engine oil but I'll have to plumb a cooler for the trans too - so either way. I'd prefer NOT to run lines to the front if I can get around that - somebody might confuse me with a conformist. Thanks!

PS: Of interest is how you routed air to the coolers too...

John - thank you. I am aware of many common methods and have searched the forum...thus my post. I'm hoping someone who has not posted their installs responds too. Are you're fans pushers? I'm guessing so based upon what you said...thanks!

Did you check out Pete Dubler's old tech article on Pelican Parts? Rear mount and the fan pulls if I remember correctly. Shows all parts and plumbing.

Thanks. No I hadn't but I just did - that won't help me unfortunately. The one achilles heel with an LS (on track) is oil temperature - coolant is fine. I'm already running a very large, 36-row Setrab, mounted in the rear but not in "airflow". I thought the 850 cfm puller fan would be adequate to dissipate the heat. Wrong. I saw a high of 290 degree RETURNED oil, post cooler. It was not working. If I backed off the rpms just a little bit it dove down to about 260. I have controlled oil temp in LS's in the past but with front mounted (and much smaller) coolers. Its all about getting airflow through them. I'm plumbing a second, smaller 19 row unit with twin 3" ducts/shroud in the rear. In addition, I'm shrouding the input side of the large cooler and feeding it with two more 3" intake air. Time will tell but I think we can achieve the temps we need to see. If not, I have no choice but to run my coolers up front. I hope that doesn't happen but if that's what it takes. Oh well.

Although I'm sure all of this has been done at some time...I haven't seen a design/location that suits my needs yet. Its hard to be the "pioneer" sometimes...if my system works, I'll pass it along to the V8 crowd.

What is your fan shroud like on the existing fan cooler?

I ran 3 different ducts to my rear tranny cooler and had the best temp results from a fan with a really good shroud
