I played it safe on gearing and timing as well, safe enough i was under powered compared to the rest. Rear motor it will run all day with no heat issue, and I have the speed to run with the rest. Bigger vents on the can I think is what the Tekin may need. The gearing I was using was 69/31 under 20 degrees of timing in the motor, blinky mode.
Try dropping a tooth and going to 71/30, can timing at 25. 170 after a full race "pull" is fine. But I think trying my changes may help get you the power you're looking for without creating more heat.
Use the data logger. I've been finding so many guys overgeared trying to get speed that they're bogging the whole car down....I know it can sound crazy at first but the acceleration "curve" with the super tall gearing is a goof up. REALLY review that data log How to we posted.

Mid motor cars also have more drag and drivetrain wrap to push with the 2nd gear and all the weight....
