Hi All,

It's been a while since I raced mod so looking for a ratio that would suit a 12t around WL? I'm thinking somewhere between 7-8.5:1 :confused:

I won't be racing the TC with a 12t (get blown away by the 7/8/9's :eek: ) but thinking of putting it the bike for a try and car mm/rev ratios correlate fairly well to bike mm/rev ratios for a starting reference.

Cheers :D

I run a 9 at 7.7. So you would want a taller ratio. I think in touring cars, for a 12 is at about 6.5-7 would be a rough estimate.
