Default Need gearing assistance with brushless conversion on savage x ss.

So I have most of the conversion planned. My main concern now is what pinon to go with. I am using the stock 47t steel spur gear. All the other gearing is stock however, I will be replacing the drive gear with a HD version and will add bullet proof differentials once the originals strip. I would like to keep my torque as low as I can without adding much stress to my motor. Relevant electronics are below:



4s lipo
hk 120a ESC
turnigy track star 2650kv motor.

It just occured to me that my motor should produce the same RPM as my engine on 4s. I am happy with the stock speed so I might as well keep the same tooth count as the stock clutch bell. My next question, Does anyone know what tooth count is on the stock savage x ss clutch bell? Normally I would just count the teeth but my truck is currently out of state (long story) and I can not count it.

Mainne,


What RPM is your motor producing? I will be getting about 39k which is the same that my engine maxes out at. I wonder if 14T will produce enough top end for me. How is heat with your 14t?

How is your top end with the 14t? do you still think that you can hit around 40mph?
