Axys pulleys are 22/43. Final gear ratio of 2.22:1
Pro pulleys are 21/44. If you put those on an Axys you get a final drive of 2.39:1. Yes this works, we have been running them on 4 sleds (3 of which are boosted 10psi at 6000').
Question is, has anyone put on the Pro top gear with the Axys bottom gear? This gets you to 2.32:1. The belt would be a little loose, so you'd likely have to run an aftermarket tensioner. This would be ideal for us turbo guys since we are geared too high stock and too low with Pro pulleys.
