[Overdriven]

Top speed on the 14v dewalt with the stock gearing was slower than the titans on stock gearing. So just swapping the motors will make your truck slower. I personally ran 21/65 which ended up noticeably faster than the stock setup with a bunch more torque too. On hot days I saw about 150 on the motor and 130's on the esc. I added a fan to the esc for safety and geared higher for awhile and abused the motor to the 175 I mentioned above.

My friends 18v needed a different spur and pinion combo because of the mounting of the motor in a Emaxx. But the overall gear ratio was very similar to my 21/65 combo, and temps were very similar to mine as well. So from what I saw theres not any real noticable difference in performance or temps between the 14v and the 18v in any way. So if you have a bunch of 18v, just use them, no need to go buy a 14v. But you will need to change the gearing to take advantage of the added torque and slower speed of the motor.

I still want to see what one of these motors will do on 6s lipo though, just for poop and giggles.
