I am currently running a 22t pinion and an 84 tooth spur in an AE t4. my temps after about 10-15 minutes on high speed test runs or a 4 minute race are roughly 175 at the end bell, 155 in the middle of the can and the ESC is 150 or so. Castle has told me these are acceptable for this system, but i still get a little nervous. My battery is either a 4200 25c 2s or 5000 20-30c 2s lipo. yea-nea?!?
Well, if castle says its okay then stick with it and when motor fries, demand a new one
I always check temps on the can but gear for lower temps (around 100-120) but your gearing on the T4 is a bit steep considering the KV of your motor!! You could bump that pinion down to an 18 or 19t and you would still have all the power needed and a bit more torque
