You could start with a 18T, i'm usually running 20/78 with a 8.5

I have been running higher than that and we run on grass and astro over here. I run either an 18/19 and a 6.5 and it is very punchy and fast.If you run on dirt then I would put a 21 ish on just to take the edge off the punch.

I think most guys are running 21T with sintered rotor motors.
