Motor temp is a funny thing.. Yes it's nice to have a cooler running motor,But now days motors best proformance are when there geared correctly for track your running. I know many top racers that for that added edge run way over 170*. Temp sometimes is HP,ya gota gear to where motor wants not temp. I run many times well over 190* outdoors and 175* indoors... Gear to where the motor runs best...
