Question Steel idler = new Internal ratio?
Hi all,

Having problems gearing my car correctly for low heat, and high speed.

Can anyone tell me how to calculate the internal drive ratio of the Cat SX2?
I need the NEW values which take into account the new steel idler upgrade as the internal gearing has now changed.

(Im running 33/22 now)

Thanks all!
Andrew.
