Was on the track last weekend (Roebling Road), and when I kept it in 3rd for a few turns, I noticed the oil temp got up to 260. I just changed to 4th going through the turns, and lowering the RPM was enough to drop the temp to around 240. When I did Road Atlanta in June, it stayed around 240 both days. I think if you are on a track that will keep you above 5500 a lot of the way around, you would need an external oil cooler, rather than the heat exchanger that uses the radiator coolant.
