Just because you don't go into limp mode doesn't mean you are ok. As temps go up so does the likelihood of engine damaging knock. Computer will start to pull timing thus reducing power. Tell me why you would drive a car for performance only to have that performance reduced over oil and coolant temps.

Also keep in mind oil is also a major contributor to engine cooling. Just because the oil may not be breaking down doesn't mean your engine is loving it at 300+ degrees. I tracked mine for two years on Mobil 1 and stock cooling system. Highest coolant temp was 246 and calculated oil temp was somewhere in the neighborhood of 310. I did not limp but it did pull a lot of timing. Oil samples always came back looking good. Eventually I had a failure. Was it oil temp related? Maybe maybe not but when I built the new engine I moved to a larger dual core radiator, external oil cooler, and high quality fluids. I'd rather see this engine running in the 220 coolant range and 275 oil range. Will see how it does when I make to the track.
