I somewhat agree. The issue for oil coolers with no thermostat is the oil never gets warm and you get sludge and poor lubrication. But our cars have a thermostat built into the oil system so not running hot enough will not be an issue.
Our cars need more cooling capacity to be run for extended periods at the track. If your engine isn't overheating, its your tranny, or its your power steering or its your brakes.

That is the point where the idrive would display an excessive heat warning, at which point the DCT would delay shifts and revs would be limited. I tried another session running with the heater on but no luck. At 100+deg ambient temps and agressive driving the stock cooling capacity is being taxed and needs help. Funny someone else mentioned the iPhone overheating too. Mine would only last about 10mins before it shut down and needed to be cooled off.

How much were you shifting? I've found that if I go to 2nd for the slow, tight corners, the oil temps will get significantly higher vrs staying in 3rd.
I agree that I would get more oil cooling capacity if I were regularly tracking the car.
