250 degree oil temp on the track ...

Small update:
I talked to a 996 driver at the track yesterday (I noticed that he also had an aftermarket oil temp gauge). He sees the same oil temperatures and loss of oil pressure.
So at least it's "Normal" and not something wrong with my car.

I think you are on the right track Chris. Use whatever tools are needed to identify when the motor is heat soaked and quickly go into cool-down mode. I wonder if I can get accurate oil temp in my climate diagnostic mode.
