If you are running on a larger track, we recommend going to a larger pinion as 4 pole motors can generate excessive heat if the RPMs are too high. We pretty much run 16 or 17 on all tracks with a T8 1900.
Also, a T8i might not be the best motor if you are running into heat issues. you might need to be using a T8.
Another issue could be the motor is old. Over time the magnets lose their strength causing you to push the motor harder, generating more heat.
165 degrees F is not excessively hot and you should be fine as long as temps do not go over 200 too regularly. I've seen Tekins go up to 300 and still be fine.
Thanks for the reply. I don't know the size of the track but here is a video from an older layout.

I know 165 isn't anything to worry about, but since I have a fan and heatsink on it it would have been higher, and yes it probably is getting to be a little older. Also in my .3 with the same setup and 17t pinion it was usually only around 120ish.
I am a big fan of running lighter weight buggies, thats why I run the T8i and a relatively small 4500mAh battery. I Came from a MIP Pro8 and since then I've run my EB48's all as lightweight (ish) as I can.
I will try venting the body first and then if i need to try fitting the 14t pinion. thanks again.
