Measure it in length that will help us all out. I run 78/24 at LIR its a medium /small track we run around 20-25 seconds per lap.

ok, so whats the smallest spur and largest pinion i can run? safely without overheating my motor? i want some good accelleration...

The largest pinion and smallest spur will kill your acceleration and make your motor overheat.
I would start with a 25 tooth pinion on your stock spur. If you need more top speed you can go up from there but I would check temps often. Keep the motor under 180F and you can do just about whatever you like.

when i had a 13.5 in my b4 i was running 72/34 and it would come off the track around 145-150, but the track i was doing that at was kinda small
