It depends on your motor and the track. In the 1/10 2WD buggy class, racers gear by final drive ratio: 6T and below near 9.40, 7.5–8.5T near 9.22, 17.5T near 6.48. On the S1V3R EVO's stock 81T spur that is about 24T for 6T and below, 24T for 7.5–8.5T, 34T for 17.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the S1V3R EVO selected.
What is the internal ratio (transmission ratio) of the PR Racing S1V3R EVO?
The S1V3R EVO has an internal ratio of 2.75:1. Final drive ratio = spur ÷ pinion × 2.75. With the stock 81T spur, a 18T pinion gives an FDR of 12.38 and a 32T gives 6.96.
How many teeth is the stock spur gear on the PR Racing S1V3R EVO?
81 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
