Gearing xb4 4wd

[franki]

Hi! Could some one suggest a starting point for gearing for medium / large outdoor track running a 6.5t

Thank you

18 or 19 with kit spur (xb4 2014).

I use 19 with kit spur at my track "Torch" which is an astro track. Works great for me.

Oh Eco my speedo must be way off I'm running 23

You're not far away from me, I run 22 with kit spur in the wet and 21 in the dry, just check your temp is not too high

i would suggest , try to go with the smallest pinion possible, but make sure you reach your desired top speed on the possible long stretch . for example , i run a 20t with turbo function . if i run a 19t i will have not enough top speed on the long strait at my local track.
