996 supplemental oil cooler

I went to several DE here in south florida (homestead and PBIR) and made decent times track and the water temps and oil pressure stayed very well in check
Why do you think the oil temp is going up ? do you have an oil temp gauge showing you so ?
I wish there was one on my car, interested in info on that one
996C2... why did you go with the 3.8 ? I mean did you do the engine work because of high mileage on your car or elective work
? 3.8 must be nice but cost must be close to gt3 price

Philoo,
I typed out a detailed response that then vanished before I could hit send. I'm not very good at this apparently. Will try again later.

FSI is building motor for my '03 996 that will be used toprimarily to drive back and forth to, and participate in, DE events in Florida (Sebring, HMS. PBIR, Daytona), plus additional miles between events to keep seals from drying out, etc. Gets very hot down here obviously. I've read Jake and LN's articles on lubrication and the actual (high) oil temps they are seeing on M96s on track in high ambient conditions.
I'd like to add a supplemental oil cooler. Does anyone have any suggestions on where to locate one given the tight confines of a 996? Also what suppliers you would recommend. I tried searching the threads and don't see anything and haven't had any luck on the I'net. Any information would be greatly appreciated.
Thank you.

Another option is the AC condenser delete on the drivers side,
Then you could put a decent sized Setrab cooler in there...
Or get a custom made to fit the center grill and run good radiators in the outboard holes.
You'll need less radiator, with more oil cooler.
Always use a thermostat on the cooler, or your engine temps will oscillate too much.

Too bad the scavenger pumps cant be tapped for a separate circuit.
I often wonder how many evils in the 996 could be solved by taking it full dry sump..
Especially if you've already taken the mufflers and could use the old position for a tank.

Honestly I'm not sure oil temps are the issue.
With a 997S heat exchanger, a third radiator, and a low temp thermostat, you shouldn't see much above 240 degrees of oil temp. If you run a good oil like driven xp9, that should be well within the acceptable range. Later model caymans see 270+ and c5 z06s see over 300 degrees, so 240 isn't really a huge deal. I understand that most oil temp sensors are in the head and may read lower than at the bearings, but still, these temps are not outrageous.

Z06's have their own cooling problems, both in the engine and the transmission until the "motorsports" cooling package is added..I've towed several back to the pits with broken engines and transmissions due to baked oil..
a 45 minute road course session at about 100 degrees will do it..
Oh and bumping the HP north of 700 doesn't help..

If you want to put a larger oil to water cooler and feel comfortable making your own brackets, we sell a universal kit that uses a Cayenne Turbo oil cooler. I had a Spec Cayamn guy that had out of control oil temperatures install one and it fixed his high oil temps:
