Any word on what the gear set up will be? Curious if they will add tooth or two on the top gear with the extra power to make it MPH.

900 Turbo R Gearing
1 reading
How does the 27/45 compare to gearing guys have been trying on the turbos? Comparable to almost a 25/38?? Seems like the new motor must pull a lot more gear since most guys were only going to a 41 bottom with 195-205 tunes. Also curious about the Mach only using 80.xx gram ramps, my 2021 with the 180 Whalen tune at 15 psi would rev to 8200-8300 with 80.6 when it was cold with stock belt. Doesn’t all make perfect sense to.
Understand that, I had a 2021 with a tune. I am just trying to understand the gearing on the Mach vs the clutch weight used.
Say you had 2 sleds pre 22 with the same tune. One sled has 25/45, the other has 25/41. Would the sled with the 25/41 require less clutch weight to get proper rpm?
Maybe just weight put in a different location ,Or higher finish in the drive spring ,Or stiffer driven spring ,Or Less helix .Best is to tune with the drive if not slipping in the driven .
Not sure what the danger in OD is supposed to mean but new motor only spins at 7250 or at least that's what doo is claiming so that will essentially lower your gearing to the same as the old motors
