Listen to it. It should rev out or hit top speed about 1/2 to 2/3 down the longest straight. If it is still pulling all the way to the corner, go down a couple teeth on the pinion. If it's maxed out 10 feet from the corner, go a up a couple teeth. Temp your motor after 5 laps or so once you have a feel you like.
