Hey Neil,
Should I spill the beans on the dyno-tested, trackside proven secret of getting away from the pack and getting 2-3 blazing laps before the motor settles in, basically it's a holeshot in the bottle okay more of holeshot in the can. On a dyno it has been tested to improve a motor's RPM/Torque to about 10%. I know you know, because you've seen Rod do this.

Hint: It can be found at all major office supply stores
I wouldn't, but the dry ice trick works just as well.

I wouldn't use them on my batteries...voltage and IR are better when warm.

BTW the reason stock motors in particular are significantly faster when cold is because the magnets develop much more flux (stronger). You will see more power throughout the race than without the ice, but the first 2 minutes or so you can really feel it.
