Forum Expert 9R review

So far I have only ridden the 9R between 3k to 5k. I would say 72 is not enough unless you are at 10k+. Anything under 4k I would say 80s is the way to go. I have a set of 80s on the way to test. I ran my turbo weights (78s) last time out and I was seeing 8400 with 69 mph track speed at about 5k. With 76s it was 8550 to 8600. This is with high elevation clutching. Not low elevation, as the low elevation clutching has a different helix. I plan on running the 76s in McCall.

My sled is a 155 Pro with a 2.75 track.
You’re gonna be the forum pouty poopy baby when you ride that 9r at 12k with your good friend Cris Boorant.

I have ridden bone stock at 12k in CO with him. I don't think it's that big of a difference personally. People don't realize that these guys rarely ride their turbos. They all prefer NA over the turbos. Why do you think when Chris is posting his turbo sled for sale at the end of the year, that it only has 200-300 miles on it?
 
Wow!! 69MPH track speed!! Just think when they turbo it next year, It should be in the mid 80's:unsure:;)

Right and wrong. When its super deep over like 9k... turbo has a big advantage. Average snow- yeah NA absolutely gets the job done, and requires less energy.

Also seen time and time again where stockers go the same places as the turbos. A good rider on NA will out do an ok rider on a turbo everytime. Turbo is more fun factor over function IMO.

I'd want a 9r too if I were you and rode almost strictly under what... 7k?

One step farther, an OK rider on NA will out do an OK rider on boost in challenging technical terrain. Boost takes a level of skill to realize the benefits, OK riders do not have that level of skill, timing and technique. Most OK riders would not admit this after purchasing a boosted sled.
 
Highest peak in Montana is 12.800 something. Lone peak out by where a lot of guys here ride is 11, 000 something. Is it just Colorado or is it Idaho too? What elevation is revelstoke lol?

Really varies. Seems like MOST (definitely not all) of Colorado, Wyoming, and Utah are 9-12k. Lots of 6-8k at popular areas in Montana and Idaho, with exceptions of course. I believe Revy and most popular areas in Canada are 5-8k.

Most riding in SW montana is affectivlu 7500-9500' with a little higher pockets in cooke city but very little over 10k that'd even accessible. Simmilar situation for a lot of thr ID/WY border riding

NW montana/ N Idaho is more like 5-7k for good riding.

Revelstoke is whack. Mid winter you can easily rage from 3-7k+. Unloading at 1500' depends what tree spacing u want if u go higher and lower. It also has huge terrain thst allows a guy to really let a boost work. Also has tight **** where a 9r would be rad. Just depends what u wanna do. It's a mecca for sledding for this reason.

CO is dumb with there 10k' unloading. You Can't breathe. Sleds can't breathe. No thanks.

It really is hard to breathe in CO. First day is miserable. By 3rd day you start to acclimate and it isn't so bad. I haven't ridden a turbo yet in CO so I don't know how much of a difference that it really makes. I'll make sure to try one this time around to see if it's a game changer at 12k.
 
There you guys go... The true forum expert has spoken. I hate to hurt feelings BUT the guys who are saying the 9R isn't in the same class as a Boost are the guys who couldn't afford a 2nd $400 payment to own a Boost and a 9R. Ask people who have both if you want an honest opinion. Very few people will tell you what they own sucks. That's why Rusty has been crying on here for a year. He dreamed his whole life to own his cherished prized possession Boost and when I slandered it, it demoralized him. He's still in therapy ?
The comment of a boost not being in the same class as a 9r is true if you’re getting picky about things… as we do on here.

I have a stock 850, 9r, and gen5 turbo. I’ve ridden the matryx boost plenty, but don’t own one.

I would put the 850 and 9r in the same class to discuss differences. The 9r is a modded version of it with the increased power and lightweight rotational. But they both ride similar compared to a turbo. They are the two sleds I’d pick 90 percent of the time. They do better for me in tight technical terrain. They are also easier to bow tie, whip, and jump with. The giro effect of the turbo is hard to control with those maneuvers for me. It’s just too much of it (I know others would disagree). I probably don’t know how to ride a turbo correctly or lack the skill.

The 10 percent of days I’d pick the turbo is on those deep days before the powder settles or if I’m going to be riding open to semi open terrain and climbing chutes.

For me it basically comes down to a two class discussions with sleds… turbo vs NA. Then sub classes for those. Basically how rmsha does it ?‍♂️
 
One step farther, an OK rider on NA will out do an OK rider on boost in challenging technical terrain. Boost takes a level of skill to realize the benefits, OK riders do not have that level of skill, timing and technique. Most OK riders would not admit this after purchasing a boosted sled.
100% I have no trouble admitting the turbo is over my skill level and exhausting to ride. Hate it!!
99.4% of the guys riding turbos shouldn’t be!!!
Am I becoming Chadly? ???

I think the only issues I've noticed is elevation also really fuels the lag. At aub 5k elevation the boost hits so hard ans fast a lesser rider can manage it. At higher elevations where it's top end shines. It also has more lag due to less air to spool up so it exaggerates the woes of guy fighting the slow response and heavier feel of a turbo sled. Curious to ride a 9r around our local 7500 to 9500 zones. I'd consider going back is I'm growing weary of the slower response.

I agree with your post, many or most guys on turbos would be better riders on a NA as they would find themselves more in control more of the time. Very difficult to be precise and be where we want when out of control?
 
That’s kinda why I posted that. I mean it seems rare your that high. 10-12 for me isn’t really going to happen even riding in the mountains. Seems more of a talking point than a real reality. Of course there are exceptions and I know bba (burandts gig?) is way up high lol. Funny thing when I first got my snowmobile I thought I’d be able to climb the peaks lol. Not so much now I have to learn and ride one.
 
A sh!tty rider is going to get stuck less on a Boost vs a 850. You can throttle your way out of a lot of crap. That being said, its usually way out of control and that's when you break things. But as for saying the Boost and 9R aren't even in the same class? Yes, technically they are different classes as one has forced induction and one is naturally aspirated. But I was comparing power and to say they are not in the same class there, you have to be a fool. The difference between a Boost and a 9R is much less than the difference between a 850 and a 9R.
 
Since somebody brought up turbo/supercharging and airplanes, I can say that, yes, that's pretty much where the technology was developed. I'm not sure if it was a land-based or air-based vehicle that first saw forced induction, but it was such an advantage at altitude that by the end of WWII, there were as many planes with turbo or superchargers as not - even lumbering bombers (B-24, B-29). If you don't ride at high elevation, or don't need a ton of power, the Boost makes no sense. On the other hand, it's huge for those who regularly ride at 10k and above.

For my purposes, I'd prefer the responsiveness and lighter weight of the 9R, but I don't ride in the highest of elevations (7-10k, typically), and don't need the most power. The Boost definitely makes no sense below 5k or so. One huge difference with airplanes versus sleds is how much of a priority throttle response is. Five seconds is not an unusual response time for idle to full power on a plane, and that's usually no problem, but it might as well be five minutes on a sled. Definitely something that would be nice to address on the Boost, but I'm not sure how you do it without adding yet more weight.

Anyway, it's good to see good reports. I'd be with the camp throwing the P-22 on the shelf. Why, oh why Polaris, would you switch from a great, proven clutch, to one that you still haven't got right? Sure, you might get a few sales because "look, a new clutch!" Then lose many more when people switch brands because they're tired of dealing with broken sleds. I'd also wonder how long the 9R is going to last. You know it's not going to be quite as good as the 850, which isn't quite as good as the 800 HO, but hopefully you can squeeze a couple thousand miles out of one, typically. The 9R probably isn't going to be my cup of tea, but after all the recall and late delivery doom and gloom, it's nice to hear some good reports on a new Polaris.
