The highest oil temps I got was a 290 on one session..and I am thinking that having the air conditioning compressor on for that session contributed to the oil temps hitting 290. In other sessions...I think I got to 280 maximum...with the air conditioning OFF. Ambient air temps that day probably ranged from a low of about 59 degrees when we arrived..to a high of maybe 80 or so. I was running partial 100 octane..with my mix probably being in the 93-94 octane range overall. I ran behind a few cars so had restricted airflow for a short period..but mostly I was running with no one in front of me.
I still am considering getting the larger Dinan oil cooler..or something similar if it ever comes out..just to be safe.

Thanks for the data. Did you run the A/C with the windows up or down?
