Big oil cooler

Are any of you guys running big oil coolers? The 3rd gen RX7 cooler is popular with the turbo 4 guys, is there a better option that is as easy to come by?

I am planning to just buy a Hayden or Derale Cooler and mount it somewhere in the front.

what do you need the cooler for? is this for tracking purposes?

is this irrelevant to those of us who are just having some street fun with a 948 build?

already getting the stock oil cooler that comes with the 951 LSD transaxle, just wondering if there's something else that i have yet again missed in what i thought was the correct budget for this build.....

Its a track related issue, not something I think the average street build needs to worry about. The RX7 oil coolers are nice though because they are cheap and easy to find. Plumbing them up can be a bit of a pain, and they add roughly 2 quarts of oil capacity. The tranny cooler on the AOR tranny is something entirely unrelated and also really only needed for tracked cars. Tranny temps should never get that high on the street even when putting 4-500 rwhp through them.


Edit: sorry, I realize this probably belongs in the general mechanical section and not here.

yay for good news; back to the forum combing and reading sloan's manual (yes it actually came in the mail; just today in fact)

I have a 16 row oil cooler from CXracing (ebay).  They are inexpensive and of decent quality, I've never had a problem with their coolers/intercoolers (can't say the same for their fuel rails). 

The 16 row cooler does an excellent job of keeping my oil in the 220 range on track during the hotest months.  I have to block it off during the cool months as oil won't get above 200.

I have a Mocal oil cooler, it works fairly well. In comparison to my friends C5 Z06, my oil temps will be 40 degrees lower than his...

Does anyone know the oil cooler fitting size off the remote oil filter housing?  I don't have the car in front of me at the moment.  IIRC they oil cooler or oil pan size are -10AN's, but the filter housing is likely an NPT?  1/2"?

Doc,

Those sizes are correct for my setup, but they are likely setup dependent.

I'm running an RX7 FC oil cooler. I mounted it in the nose where the intercooler goes on a turbo car. It took a few iterations of the setup to get everything balanced and cooling well but now it's working great.

The cooler is actually plumbed backwards and so I removed the Mazda thermostat. I have an Earl's 160 F thermostat mounted underneath and there's a 3 qt Accusump and remote filter behind the passenger side headlight. The water radiator is a fancy all-aluminum deal from Wizard.

I cut open some of the bodywork in front of the radiator and vented the hood as well.
