The best method that I've found (D. Arnold posted this before) is to gear the car with minimum motor timing (for laptimes) and then turn the timing up from there if you need a little more straight line speed. If you have to turn the timing way up (long straight) you may have to gear back down a touch to keep the motor from overheating.

Max timing normally makes the motor run hot and heat is just wasted power.

Personally, I think that gearing for temperature is pretty stupid. Always check the temp so that you don't cook the motor but gear for laptimes. Sometimes a motor will be faster at 130 degrees instead of 160.
