I think perrin mentioned they saw a performance loss at 230F. But too cool is just as bad as too hot. So where so we draw the line?

I talked to a few more people involved in spec teams. 215-235 seems to be the magic number for track. If you are running 0w20 obviously lower is better. if you start seeing higher temps switch oil weight.
For daily driving 185 to 215F is optimal. After testing this is totally reasonable if you have a cooler behind the bumper. For the Perrin kit in front and center you will see the oil temp stuck around 165-175F until you go WOT to 6000RPM a few times. From there it will go right to about 185F.
If you idle, no clean air it will climb on its own. The settling point should be coolant and oil temps almost identical for daily driving. 190 to 195F.
Winter will be a different story...
