you say you are on minimum timing. make sure you are fully clockwise on the back plate as this is minimum timing. ive heard a few shops saying it is fully anti clockwise which is actually maximum and although quicker generates a lot of heat. i know im 1-2 teeth lower geared than i would be on a equivalent speed passi or nosram as the motors love to rev. if you are still struggling with temp after all this then try a larger rotor as this helps to drop temps as well. if you have any further questions feel free to pm me as have been running these motors from the start
