No limp mode, thank goodness, and was able to drive home fine. It was nerve racking thinking the car was going to shut down at any moment. There was no way the car would make it back to the track without an oil cooler.

I took it to the track recently for 2 days with air temperature in the mid 80s. This time on the Thunderbolt at NJ Motorsports Park. Oil temp highs were around 200, maybe 210. Normal and spirited driving keeps it at 180. Long story short, this was the best first mod for me to do. I am pleased with it so far. The only thing remotely negative is that the outside air temp reads incorrectly high. Perhaps that thermometer is obstructed by the cooler. It isn't a big deal to me though.
