Based on novak's GEARING RECOMMENDATIONS chart you should be around a 3.5 fdr. Then you can go from there on getting the right ratio, as with some esc/motor combo's you might need somthing that is higher (more acc.), and with others you might need a lower ratio.

If you want to be around 3.5, but would like it to be a little cooler you can start around 3.8, but heat really won't be a huge issue if you go by novaks chart.

for the chart

For the tracks around here (80ft to 110ft straights), we gear from 4.0 to 4.6 fdr depending on track size / layout.

Im around 3.65. 54/98. With near max can timing. Might go back up to 3.8ish just to pull a little harder out of corners.

I run 3.9, 17.5, blinky with 8* on the motor. I go up or down a couple teeth on my pinion depending on the longest straight. My temps range between 120 and 130. The more timing you add to the endbell of the motor, the more RPMs the motor is capable of turning, but at the cost of added heat because it is pulling more current. With my driving style, which isn't great, I prefer minimal timing on the motor, then I can use the low end torque in the infield.
