I want to try a setup(gearing) on my sled to run a 1:1 ratio when climbing any one know what the track speed would have to be.

 

[Barrett]

aproximately 78mph @ 7800, @ 1:1,
assuming the 3" 8T drivers are 24" in circumference, and the sled has 60/60 gears

 

[WyoBoy1000]

so what gears would be 1:1 at 65mph.

 

[Barrett]

so what gears would be 1:1 at 65mph.

54 input / 66 transfer (2.74:1) would give aprox 64.4mph @ 7800, @1:1 clutch ratio
