even if ignoring legality and spirit, i htink cooling the motor would be a much better way to 'boost' performance. a simple way we used and was effective (for our OCCRA robot) 2 years ago was to have tubes connecting the exhaust ports from the pneumatic cylinders to blow into the motor endbell. (we used our cylinders almost continuously that year and fans are not legal in occra or we didnt have any available... dont remmebr which) but as a concept it worked well. but then again from last year we learned how to make a more efficient drivetrain with much less friction and got a more 'easy on the controls' driver and havent burned a single motor since.
