      Hi,

      I’m a italian boy and I’m sorry for my english!!!

      Anyway, also I have a tm k9c, it’s very good engine!!! The track with  the main straight of 1/4 mile It’s very long. I think that a good starting point to gear ratio is 19×22 !

      At 13800 rpm your final speed will be 170 Km/h

      I’ve raced TM motors on big road course,  a 19/21-22,  18/21-22 will work depending  on weight and hight of the person?

       

      best of luck:)
