Need to drop your oil temp?
I removed the stock oil cooler/warmer and replaced it with a B&M stacked plate cooler. My oil temp plummeted 30°. I was pretty surprised! I just did a test drive, 90° ambient, 160° oil temp, 180° coolant (stock radiator), and 150° trans temp. I used my previous trans cooler for the oil cooler it's 8x11" in size and replaced it with a 11x11" unit.
With the stock unit my coolant temp was typically 185° and oil at 195°. The separate air/oil cooler was simple to plumb. I'm curious to see what temps will be like tracking the car. Here's a picture:

B&M stacked plate coolers are pretty darn good... Im use one to keep my transmission cool.
I'm surprised the a 35 degree drop in oil temp only changes the coolant temp 5 degrees.
Did you plumb in a thermostat for the oil cooler?
Did the larger cooler change your transmission temps?
Please post on how the temps work out on the track.

Looks good, nice install.
I used a "Permacool" system from Advance meant for RVs or something. The filter plate has a built in 180 thermostat and that's where it stays. I used to see temps in the 230s or something (I want to say even higher because I remember being pretty worried about how much higher it was than the coolant temp) with no cooler at all. I used to monitor the temp pretty close but have all but forgotten about it after running this for a few years now. Well worth the effort.

I was wondering if anyone would note that. I thought that wasn't much drop either. I do have a 160° thermostat in there. So if the stock radiator could cool it down anymore the 'stat would allow it. A 5° drop is inline with what occurred after I took the stock trans cooler out of the system. IIRC when I bypassed the radiator cooler water temp went from 190° to 185°.
I can't compare this trans to my last for temps, it's non-lock up. I almost put both coolers to the trans and I may yet have to add another or go up in size. I'll see what the track brings.
I used this http://www.summitracing.com/parts/HDA-211/ oil cooler adapter from Summit. It claims oil starts to flow at 160°. I've noticed it takes quite awhile for oil temp to come up. The "thermostat" part inside was a simple piece of spring steel. I was tempted to remove it.

The extra quart [Amsoil 40 wt] and the cooler kept oil temps under 210 degrees. H2O stayed about the same. The ambient was 96 with about 85% humidity. Hot in Ga.
Bear in mind this was a temporary rig, as well. We mounted it under the drivers seat so it had zero affect on H2O and ATF temps. The auto transmission in the Queen did not seem to mind, but then I don't have a gauge so "Don't Ask Don't Tell".... It didn't break?
I expect even better results when mounted in the track P.O.S., where the OC will be in an improved air stream.
We have been arguing about where to put it, and if a different dimensioned radiator would be practical, allowing space to mount the OC next to the Rad., for a clear shot of air through the O.C.?
Pluses and minus...........?

Will water vaporize quickly at 212*F? Sure. Will it vaporize as quickly at 180*F? Or 160*F? No. But still mighty fast.

With my last cooler setup I got to 245° oil temps and was shifting the engine setup (SR) at 5,500. I'll be using more RPM with this MR setup so I increased the cooling level. At one track my trans got to 225° and started not to shift well. I'm trying to keep the coolant temps low too, for reduced chances of detonation. So before oil temps went from 195° on the street to 245° on the track. 160° isn't my goal for street use, I just want it cooling enough when I get on track. Amazing removing the stock cooler/warmer made such a difference.

I think the lower oil temp changes what combination of driving and ambient temp that constitutes a "short trip".
This link says it better than I ever could.
