Polaris makes money off the forward twist from belt sales. They helped create belts that don’t explode but only wear out quickly with how the engines come aligned from production.

 

You can solve all this with a magnetic cvt no belt need no secondary clutch needed.

 

my kid and his buddy have the same sleds same tunes everything but the clutching. One has the p85 with the polaris secondary the other has the p22 with a stm secondary. who ever hits the gas first wins the race.

 

Winter is coming fellas. Let the testing begin. Who has a Boost that wants to play? Lol

 

Aaen's dead.

 

I am taking the recommendation found on post #30 in this conversation. Looking forward to this winter.

 

See there was issues/changes to the mounting bolt on the P22. Now there is no less then 4 aftermarket companies making a product to lock the spider on simular to the jam nut on the P85. I'd be running something to lock the spider in place on the P22.

 

Keep in mind some of the clutch issues are probably created by the owners or shops not using proper diligence during service and installation of clutch and parts to include proper torque and retorque . I’m not a huge p22 fan. But l think some of this is end user . I personally would not use the aftermarket “lock” that require gallons of locktite. Just my opinion

 

What do use for shims?

 

A slotted washer for the left front. A slotted motormount bracket for the left rear.

 

they break from flexing. or loosen up. this is what i see. the Spyder retainer is a must do for the p-22. i did a clutch kit, TRS valve, and a carbon sled retainer, i torqued the clutch to 110 ft. pounds ran the sled and retorqued it. 2025 boost dynamic. guy put just shy of 3000 miles on it. clutch just as tight as the day a put the clutch on. not one issue, this was the guys third boost. 2 other clutch kits on the other ones. loose clutch bolts, one broken bolt which destroyed the sled. the the clutch kits sucked. needless to say i have another life long customer. guy kept the sled because it is what it should have been. and his 5 other riding buddy's all have my clutch kit's, boost and 9R'S. that's how you know you did it right.

 

Found the same on my brothers 9R. 2000 miles and never took additional torque. The retaining sleeves definitely work.

BTW, about 6500 miles in your a arm bushings. Virtually no wear on them. 👍

 

I understand using regular Loctite on titanium may not give the best bond, but in my little test this spring, the blue Loctite gel seem to do its job since once I loosened it I needed to use the ratchet to be able to un thread the connector the rest of the way due to the resistance in the threads from the Loctite. When threads are cleaned, I can easily screw the connector in all the way by hand. I really don’t think once it’s torqued down and then the mounting bolt is torque down that the connector will loosen up. It could only really loosen if the main bolt loosens up and the main bolt seems to stay Perfectly tight once the connector has been installed. I will just check the torque periodically and make sure it hasn’t moved. If it does, then a titanium specific bonding agent will probably be the right choice.

 

The Loctite 243 will work, it will have a longer cure time on Titanium and other sensitive metals.
Or use the hard to find, exactly correct product:

Loctite 2432

 

Ran Carbonsled's connector on my 9R from day 1 and never had an issue in 5000 aggressive miles. Tightened to recommended torque at installation retorqued after first ride and got just a squeak tighter. Checked torque again at 500mi, 1000mi, and 2000mi and never had bolt move. Because of this post just went out now and checked torque, and not a whisker of movement.

I'm not 100% sold on the P22 and will be trying a P85\Tied combo this season, but I believe any of the threaded connector kits are the proper fix for the P22 blowup issue. Hopefully Polaris is reading this

 

Kind of makes a guy wonder.

 

^^^ EXACTLY 👍

 

Amazing what man was able to accomplish with a straight edge, circle compass, protractor, slide ruler, trigonometry, paper and a pencil!

 

In do believe that the design of the p22 is flawed. But here are some reasons that (I have both and hopefully will dial the sled in with both at some point ) that I’m first gonna concentrate on the p22. I think Phil is right that the p85 is on the way out the door so I better figure out how to make a 22 work and stay together. Local and not so local race rules dictate that stock oem for the model ckutches must be used. So if ya want to legit race one ya can’t change the clutches in alot of the classes. Next I don’t believe the p85 can carry enough weight esp in the right spots to keep rpm in ck. When really stepping on the boost pressure. So it’s a necessary evil to play those games. And that is why I don’t just shelf it

 

Once you do the retainer LID, most P-22 issues are fixed IMO. Here's a good video on it. The hammering shown in this video does not happen as violently as demonstrated because the weights are still opposing the effect anytime rpms drop as long as you are above engagement rpm.

when Chris Burant was blowing a p-22 clutch up almost every day? why would Polaris release it to the public? the p-85 has been tested since 1985 racers don't take chances on stuff like this. and like what the guys that know have been saying. the best mph and et is with the p-85 over the p-22. only one fan boy on here that thinks he knows? he doesn't

Exactly. Funny how many have switched from a p22 to a p85 but you never hear of anyone going from a p85 to a p22.

LOL! Just what do you think makes the P-85 faster than the P-22?
1. The P-22 weighs 1 lb less.
2. Has the same sheave angles as the P-85.
3. The weights are not much heavier at the tip.
4. The weights are heavier overall because they are wider at the pivot pin and because the Boost and 9R make more hp.
5. The Boost also has a helix with 2 more degrees finish angle.
6. The P-22 has a much smoother engagement.
7. Deflection is perfect all the time.
8. And, the P-85 doesn't grip the belt any harder that the P-22 despite opinions to the contrary. That's mainly controlled by the 2ndy.
9. Eventually, the knowledgeable racers will have a much wider selection of weights. This is the main reason that the P-85 is still being used.
10. Certain testers have used much different belts, etc., in an attempt to bias their testing to suit their opinions. The P-22 is easily superior to the P-85 and eventually will replace it totally IMO. So, better learn how to tune it properly.

Rather than talk, why don't you go and test. You might actually figure it out then. I'd say using the belt that the sled came with is right way to test.

That's too bad that they wont let you use another clutch from the same manufacture that is currently being used on other 850's. Even the factory drag racer Boost runs a p85. Will they allow you to mod the p22 so it wont come flying apart?
The p85 will carry more than enough weight for any Boost using the factory turbo. I would say that the p22 has much more of an issue with weight than the p85. Guys are maxing out goofy looking p22 weights trying to get it to pull. Meanwhile sleds making the same hp with p85's have zero issues with that and need way less weight to get the same rpm. People have been using p85's with turbo applications for damn near ever.

I believe that they would not have an issue with one of those locking collars etc on a p22 but if sled came with a 22 has to have it and the other way around. Same with secondary clutch not legal to run a tied on a sled with a tss-04 from factory. There are “higher “ classes were you can run a 85 or even a stm etc. but at that point your dealing with race only sleds and my sleds are full time trail part time race . So I would literally be throwing money and time out the window to get knocked in first round or 2 . How much weight can a 85 carry ? And since I have never messed with a 22 I didn’t relize a weight difference between the 2. I thought if a 22 needed 100 grams of weight then the85 would also need in that ballpark I guess I wrongfully assumed Polaris had them functioning the same as far as that goes. Yes I’ve had some buddies run aftermarket turbos with the 85 at around 230-240 maybe Hp. Like I said I have a p85. That I can use regulatory but I have no choice but to work with the 22 also

 

The P22 weights are very wide at the pin. That added weight does not contribute to squeezing the belt.

Here is one I’m having a hard time figuring out why offset the weight instead of center roller ? Yes im familiar with this wide area and its weight just speaking for myself i was taking about much heavier weight than that lil bit. How much weight does it take in a 85 to control rpm on 240hp aftermarket turbo set up on a 850. give or take on flatland. ?

 

Interestingly enough Will at velocity prefers the P22 for aggressive riding and higher hp sleds. He admits the P-85 is easier to make perform better than the P-22 for people doing simple swaps or comparisons. Once tuned properly he says the P-22 performs as well and 2024 or 2025 clutches with updated buttons and spider( not sure what year the buttons were updated) is more durable button and bushing wise with aggressive use and or boosted hp. Just relaying what he told me. Theres a ton of weight options now for the P-22 so no one can blame the lack of weight options. The factory setup is not it for sure, on the 9R anyway. Anxious for snow as I will try both clutches and see which I prefer

 

Those are my findings also. There really is no downside to the P-22 once some of the minor deficiencies are fixed. The biggest benefit is never having to adjust deflection. The 2nd biggest is easy spider removal with no special tools.
