Actually, I find an oil temp guage to be much more informative than the coolant temp.

The Covette C5 and 6 has one and it is not a fake out, ie it reads temps by degree and changes pretty quickly.

Using that I have found that the oil temp will usually run about 10 degrees hotter than the coolant, UNLESS you are flogging it. In that case, the oil can get REALLY hot.

If i were tracking my Porsche in the CA heat, I would be running Red Line oil or M1 15W-50, both of which are more shear resistent than the M1 0W-40 oil.

Also, if I were doing a lot of tracking, I would likely get larger oil coolers.
