I'd change the gearing before getting a heatsink. The heatsink will only reduce temps, but won't do anything for the longevity of your equipment. When properly geared, your equipment will run cooler. Simply adding a heatsink only masks the problem.
Yes, gearing can be a problem. Find the stock gearing and drop the pinion 2-3 teeth. All you need is torque.
However the heatsink and fan are really a great investment and they do work. Dropping the temp. by 40-50 degrees is amazing. I can go "all out" with mine and when I stop and pick it up you can watch the temp fall. If you think about it, the motor is inside of the car and you're drifting so you don't get much air-flow. Also, on a sedan, the motor is very close to the asphalt, which is hot. It just needs extra help cooling.
Alex A- Do you have a temp. guage? How hot does it get? What motor are you useing.
crash_alot- Where did you get that heatsink. I have been thinking about ditching the bread twisties.
I can't complain, it works.
