Sorry Dan, standard spur is 81, I think! The only pinions I can get are 12 and 13 or 24,25,26,28.
When I ran the mid last year it had a 23 on and still topped out too early down the straight with the 20 turn Saturn. So I was thinking of going bigger not smaller!??
23 pinion on 81 spur gives ratio of 9.30.
You know I have not got a clue how this works so I will just keep throwing bigger pinions at it until it is fast down the straight with a good amount of infield poke!
