If you're looking for pure temperature induced limp modes, those don't occur until 290F. All N54 powered vehicles will go into a reduced power mode after sustained temps of 270+ (engine malfunction!, reduced power). So, you can still be racing, but you're going to be half as fast. The other guy was racing in like 80 degree weather and his 1M was over 270F. Even if BMW removed the reduced power mode, the ECU will seriously dial back timming, and thus power, once it sees oil temps over 270, and air temps over 80F. So sir, I'm sorry but 1M stock cooling= FAIL at the track.
