Had my first onroad race in a few years with a 1/12 pan car. I used a Speed Passion 17.5 1 Cell motor in blinky mode with a GT2.0 Pro ESC and TQ Booster.

During the race I noticed that with my roll out at about 95 I am assuming with for the track was not too far off, the motor was getting up to 160 degrees temp wise. I thought I was undergeared so went up to where my buddy was with his MMM that was running cool to the touch but it feel even hotter. Motor also seemed to act erractically

Eventually I was not able to finish a heat as the vehicle was kind of start and stop depending on if I had the power on the ESC on as well as the TQ Booster.

I went ahead and took out the Motor and it felt kind of gritty and could hear it as well.

I put in a standard competition 3.0 17.5 motor I was going to use in a touring car and instantly was better, motor was cool to the touch and I had speed not too far off of everyone else considering everything.

Now my question is this, what should I look for in the motor? What potential issues could it be causing this?
