Turbo pro 800 (2013) what gearing to run...

[Frankenytro]

I have a 13 pro 800 running 10-12psi. Wondering what everyone is or was running for gearing with 8 tooth drivers. Looking for real world experience and options. With my belt drive I have 6 options. Thank you in advance!

2.10:1
2.17:1
2.25:1
2.33:1
2.42:1
2.52:1

I ran a 2.14 with 8 tooth. Lame. Hot clutches, lazy backshift, belt dust. Gearing was way too high. Went a 2.32 and it was better but not a whole lot.
If it was me, I would gear it so it uses the full primary clutch sheave and a little overrev. This will load the clutches in overdrive and turn the over rev rpm's into mph.

2.25:1 worked well for me. Clutches stayed cool and pulled like a freight train.

7 or 8 tooth drivers?

good point....I would have 7 tooth with the 3"

Its all good. We recommended the same gear ratio as a 7 tooth is approx 2.45 final so its pretty close to 8 tooth 2.52.

I guess it depends on what your hoping to achieve.

Snappy response from the machine is what I am after. Don’t need 130mph track speeds for most of the days riding but do like to climb every now and then lol. The ultimate would be fighting the ski lift and getting into suspension tuning to accommodate for the ultimate useage. I am running 2.17 now but would like to try something different. Kanedog has a few good points that he has mentioned to me about going with 2.52. What do you think?
