I will say at the beginning of the yr the 850s were killing the 9r. by the end of the yr the 9r guys started figuring it out and the game started changing. I’m sure when next yr starts on anchor bay the 9r are going to very hard to beat.

 

Apologies if its been mentioned in this thread already but what should we be targeting for rpm on stock 9r? Ive seen some talk of 8250 and other talk of 8350-8400. Whats being found as quickest in real world conditions?

 

The 9Rs have a broader peak power curve then the 850s. We run ours at 8300-8350 with a trail set up.

 

8300 rpm seems to be the sweet spot on these.

 

here is one issue with the p-22. the ctr. shaft where the belt rides is 1.973 dia. the p-85 is 1.610 both are about 8" in dia. so the low gear is higher in the p-22, which can create a bit of belt slip. we could not beat a p-85 out of the hole. same 9r sleds. once that happened the p-22 clutched sled couldn't ketch up. so here is another interesting find. we made a bar jig so we could spin these clutches in a lath then take power away. the p-85 made 2 complete revolutions more then the p-22 and if you put a open cover on the p-85 it made one less? the old enclosed polaris clutch went almost three revolutions? so this tells me air drag also makes a dfference. i suspected this so we made a simple set-up to try. and it proved right. this is where the p-22 loose's is in take off.

 

What is the weight of these clutches? Are you sure your not observing rotational inertia?
Also at the speed needed for aerodynamics to play a factor, how are you counting revolutions?

 

Sorry to burst your bubble. You are comparing a diameter in a P-22 with ZERO deflection to a diameter in a P-85 that isn't at the diameter of engagement. What's the engagement diameter? I already measured them. It's much closer and depends on deflection setting.

You can run a P85 with no deflection in the secondary.

I have access to a 3000'field. Bring out your P22 equipped Boost. I'll bring my GoPro and my drone to prove to you the P85 simply works better in low ratios. I'll bring out our 25 9R too and will happily swap clutches . Real world testing Phil. What does your Boost have on it? 700 miles? My 22 XCR has almost 9000 on it. I can prove my theories. I test just not sit in the garage putting ratchet straps and magic fuel pellets in my sled. I'm calling you out. The field I'm talking about is less then 1 hour from you. Win or lose I'll be honest with everyone here and will give video proof.

LOL!
Exactly how do you run a P-85 with no deflection? This means the belt is riding on the hub. or has a secret length and width belt that will never be able to be set to a acceptable position after wearing a little. Not very belt friendly. 2ndly, WL isn't safe to run on. Where is this mystery lake? Anchor Bay? Or is it a field? Sorry, I don't believe your "theories" and don't try to compare apples to oranges.

 

Can I come watch? Where are we going.

 

Well I'm just outside of Detroit

 

I think him and Northstarrick should box. Winner gets a free jug of VES

 

😵‍💫

 

we talking punch boxing or boxing parts for shipping. I’m pretty fast at the shipping I will take all challengers.

 

This is probably the most useless thread ever at this point. It like a car crash and I can't look away for some reason.

He literally asked you two legitimate questions and wasn't a dick about it but you can't answer for some reason?

Doesn't matter anyway he’s wrong no matter what !
Won’t be long and you won’t be able to buy a sled with a 850 or without a P-22 so hopefully they go to brand x .

Still waiting Phil....

Not picking sides in this fight cause I could really give a shit but you did post that you can run a P85 with no deflection. Maybe I'm misreading what you were trying to say or just didn't understand?

"You can run a P85 with no deflection in the secondary."

100 % I implied that. It will smoke the belt non stop but in a race you can

 

You could've just said you didn't have any specific measurements because that's all he was asking for, the actual measurements, but we can just caulk it up to my 3rd grade education and leave it at that.

 

He's a clown

 

Funny how Phil hides . I'm still waiting on his P22 Boost to show me what's up. This is public. I called him out twice now.

 

You are entertaining, but I guess Bozo was entertaining too 🤔

 

🍿

 

Phil’s ready

 

That's probably a better race lol

 

My other brain gets me into trouble constantly!!

 

I see why. Reading comprehension. Try it.

 

I now have a clear understanding of "keyboard warrior"

 

So, another expert who isn't speaks. Head of Motorsports? Doubt it.

 

I never said the P-22 was better performing vs the P-85. I said it has several advantages over the P-85. The biggest is automatic deflection maintenance and very consistent and smoother operation. So say many other tuners like SLP. I posted this info and many disagreed because it was premature info before many of the current issues arose. My Boost doesn't have ANY of the issues as of yet. And, I'm not afraid to test it against any similar sled and already have with great success. But, I will not race it on dirt and no snow to keep it cool. So, either find a proper lake with those amenities or wait until next season. You will be surprised when it will be seen to be very competitive.
Nothing like Mike says. I can also offer a friend's mildly tuned Boost also with a P-22 and proper belt as a potential closer competitor to your moded one and he does grass race.

Don't nake me look up all your post saying the amuertereo

Oh. I thought we were going top end. Well, never mind then.

I told you I have 3000' to play with. I'm not afraid. I told you it's not in your best interest to run 660. But apparently your P22 Boost rocks it out down low.

Again I've called you out . How many more excuses. I'll send out the address for anyone that wants to watch . The grass won't hurt your sled or make it over heat. I'm still waiting for you to pony up. My little 900 with the P85 waiting

 

My my. Aren't we cool. So, people like you just test without thinking about anything? I'm not impressed. LOL! You don't seem to know what creates belt pinch. It isn't the primary. Typical loud mouthed sled rider. Better seek advice from your other brain.

My 900 is stock. Anymore excuses? I'll show you in person and you tear it down. So your friend has something for my 900? What's wrong with your Boost? I've giving up 10 HP. My sled has 8500 miles on it . It's a trail sled. Should I actually bring out something fast? Sorry you laughed at me running 4.80s years ago. Come talk to me after you keep sniffing Ficht pellets

 

Both junk
🤷‍♂️

 

they both work.
for the hp the turbos are pushing a 4 arm is better than both as far as tuning goes
9r should be better than an 840 it has more hp. I’ll believe they run better with the stock programming than 840s when I see it though. There’s some hp in a tune to be had with them

 

One of the little realized benefits of a .375" longer 2325 drivebelt when using the P-22 is that the overall gear reduction provided by using a P-85 can be maintained at launch by allowing the belt to ride higher in the 2ndy. The advantage of that VS the P-85 with a shorter belt is it allows a better contact patch in the primary. Less slippage. This is another advantage of the P-22 with the roller bearing hub.

If Polaris hadn't had excessive forward engine twist and minimal 2ndy float as well as inconsistent P-22 dimensions, the switch to the INFERIOR narrower and shorter 2348 belt as well as ECU reflashes wouldn't have been necessary. My Boost and many I've worked on don't require any of the factory fixes.

The new belt was a dumb fix imo

 

Hmmm… p22 with 2 choices of belts, one narrower but the same length as a standard p85 belt that we can all agree performs bad. Or the 23 Boost belt that is the same width as a standard p85 belt but is longer.
Does the longer 23 Boost belt with a p22 have the same top speed potential as a p85 with the standard belt? How can it if the engine is placed in the correct location?

Fact is given the belt choices we have with both clutches, (this includes the wider/softer CC p85 belt) the p85 will always have an advantage in either starting ratio and or top speed.
We should discuss why the p22 requires so much weight to perform the same job as a p85.

The weights used in a stock P-22 and the geometry of roller location vs weight pivot points vs the P-85 are different so I've been told. It isn't just a simple weight to weight comparison.

 

Weight is shorter due to basket webbing
P85 has a better starting ratio
I personally like the p22 for trail and pursue using it because I think the p85 goes away
Common to go from higher quality to less it seems 🤷‍♂️
I like the stms because you can use any weight you want of the millions out there
