Oil Coolers and Over cooling

AM Perf was running a custom oil<->water unit combined with an upgraded radiator in longer competition runs, seems like it worked for them. It's probably the better and cleaner solution in general. It will warm up oil faster, the oil lines are shorter and safer (oil<->water unit inside the engine bay, behind the radiator), less bulk/weight out at the tip of the car, etc.

I think Travis has been trying out some Laminova units: complete-oil-coolers-ec54 - oil-coolers - The Laminova heat exchangers - Laminova, but he's been focused on other issues lately. I really think with the right Laminova and an upgraded (e.g. CSF) radiator, you shouldn't need to run an extra Setrab core out front except perhaps in the most extreme of conditions (long races in the desert? I donno).
