so assuming we have the same gearing and same condition belts, same clutches, @ a conservative 4500rpm, I will move 25% faster. Then again, the total rolling diameter is 26" from the top of track to the hard surface (like on the lake) adding another 12% distance-to-rotation ratio over the OEM track setup.
but all of this means nothing in the woods and I would rather have your 29hp kawa with loads of torque at low rpm where we need it. (but it was cool to fly by 10 argo on the lake)
... but before swapping a 29hp kawa, I would try the firefly engine with 55hp @ 6500rpm.... a very easy swap in a Max IV.
I take it your the black sheep of the family up there in Argo land? My brother in law said when he goes up to the cabin, its kinda lonely being the lone Artic Cat in Ski-Doo country.
