    New ACE 1630 has a maintenance free supercharger?

    So the new charger on this motor has a smaller wheels and spins faster. It's also noted it is now maintenance free. No information on the clutch design though.

    Very curious to hear thoughts, discussion, etc on this.

    Wonder if a retrofit for older skis will be possible.

    Watch the vids on you tube etc. has a dynamically balanced shaft, more clutches, more clutch surface area. The shaft is about three times the diameter as well.

    Obviously, the big and final change was the dramatically improved supercharger. The new centrifugal blower produces an impressive 30-percent more boost (18psi) thanks to a more efficient (albeit smaller) wheel that spins 8-percent faster. The new wheel features an aggressive 32 blades – or double the blades of the outgoing design, and features 8 steel washers and two composite bearing packs at either end of a near inch-thick shaft. As per Lachance, all superchargers are individually tested prior to assembly ensuring that this supercharger is 100-percent “maintenance free.”

    US models limited to 7700/65mph! That blows. Slowing it down even more. Granted a reflash would remedy that but still blows fresh out of the crate.
