To those that say there isn't an imbalance or wobble built into the pDrive clutch, there certainly is. There is a 0.024" runout on the sheave which is intended to keep the belt at a constant tension, and reduce vibrations.
I'm not certain which way I'm going to go with my primary yet, little bit disappointed with the close minded naysayers who can't understand what I'm trying to do, but I'm here for feedback. I don't get to choose what someone else posts on a public forum.
There are aspects of the pDrive which I find quite attractive. Clickers, and being able to easily adjust flywheights on the hill being the two major ones. I like the idea of using the clutch to reduce vibrations, but I'm not sure that the elevated temperatures are worth it.
If a DJ kit can bring the temps down enough that sure is one very possible option. I've put his kits on all of my previous sleds, and a lot of my friends sleds. So If he says his kit with the GNR alignment will get er done, well I have to give that some serious thought
The CV Tech clutch is also very attractive as I have talked to several people from all brands through the years who have switched the the PB80, every single one of them raves about the switch. Problem is information on them regarding the 850s is almost nonexistent. The CV Tech clutch would also be the next easiest clutch to tune on the hill.
The Polaris is less of an option, because well, putting a Polaris part on a Ski Doo just doesn't seem right. At least CV Tech is keeping it in the family, sort of. Their practically Ski Doo, right next door anyways...
I just want the best possible clutching, which means efficiency which means less heat, and as I've stated before I don't like the amount of heat being dumped into the crank. With no clear answer as to why there have been so many PTO failures, anything I can do to promote longevity and reliability.
Man Grip'N'Rip has some awesome YouTube videos! Got sucked down that rabbit hole for a bit, but well worth it!
I had planned on installing a DooDr floating secondary, but after seeing his videos I'm not sure. My static alignment numbers are good, but now I'm thinking I should buy his kit. Regardless of which clutch I choose I can always align the motor the the pDrive
