It is a combination of ESC setup, physical motor timing, and gearing which affect temperature not just one particular.
In general:
Reducing the amount of timing = lower heat.
Increasing the delay before the boost timing is added = lower heat
Increasing the RPM window for the timing to be applied = lower heat
Proper gearing for the above settings = lower heat
I have not run 21.5 open ESC on that large of a track, but I have run 17.5 open and was geared around 6.4 FDR. I would think trying an FDR of 5.0 would be an interesting experiment. The extra timing needs the RPM to work, and if your overgeared, the extra timing just causes heat. If the speed is not quite there with 5.0 FDR, but the temps are good you can begin to advance the motor timing just a little at a time.
80C on the motor after a 6 minute run is about the maximum I would want to see.
