Of course 80°C to which I referred were outside, we must always consider that inside the degrees at least doubled, so when we have 100°C outside, inside we definitely over 200°C, too many for me, for any kind of magnet.
Its always interesting to see which motors heat up more after the car has stopped.
Next time you finish a race, measure the temp right after the race, then put your car down. During the next race (say 4-5 minutes later), have someone temp your motor, and it will more then likely have risen 30-40 degs F. That would be a better idea of the internal temperature of the motor.
