Here is the deal: went from 15 tooth clutch bell to 17 tooth, so it is 13% more teeth, or 13% faster. Also, went from 60 tooth spur to 56 tooth, so 7 % difference there, or 7 %faster. So is it safe to assume the total difference of gearing now is 13%+7% = 20% faster????
The truck is an Nitro Evader, not that that will matter, the original speed I guessed at 38 MPH, so with 20% more top end speed will it now run 45.6 MPH?
Thanks, Joe
Haven't ran it yet, plan on having some "me" time tomorrow and run it to see if I notice a difference, or to see if it will even move off the line without a push from me with the new gearing.
Is that the BX gearing? If it is.. then your calculations wouldn't be correct based on your first speed. Thx BX (fastest of the evaders) has been officially clocked by two review's at 34.X MPH. So an ST would never hit that with stock gearing and stock sized tires. The only way your going to hit 45 is with the 21t or 22t gear ran off that custom clutch bell you can get for the evader (with the 56t bx spur gear).
