my boost VR1 is great sled, only 500 miles last season,cannot waite for this season. great engine. love my 022 VR1 850 129 but boost is now favorite sled

The Trump train has a Polaris v-16 2 stroke at 850 CID per cylinder and turboed to make 13,500 hp @ 1150 rpm's. thats 13,600 CID and has 430 gallons of amsoil interceptor oil on board and burns liquid hydrogen! its hard to stop a 2 stroke trump polaris liberty powered 2 stroke train!
Shout out to the Production Team. That piece on Turbo or No Turbo was crystal clear. I would love to see a drag race with all the engine options side by side then on a trail circuit . Light weight 600 or the Mother Load 9R ? Another question is the longevity of each option ? Thank you. Dale
I just bought a 2025 vr1 dynamix 650. Can you explain the changes to the 650, 850 and boost updated pistons,/oil injection updates??? No one is talking about this anywhere!!
From my take, you can get greater power and less parasitic loss without worrying about turbo lag because the sled needs to reach 2500-4000 rpms before the clutch engages anyway. So, at full throttle from a dead stop, you are more than likely at or near full boost anyway.
Mistake. Mine has virtually zero lag. And now with a tune and clutching it’s insane. 220 hp. 15 lbs of extra weight. And no compromise. Everything else feels boring now. Only if planning on staying totally stock I’d consider a 9R. Even then I’d lean to the boost
A well clutched 850 will outperform a stock 9R. The 9r is a flop in my opinion. Dealers full of holdovers. Boost price for NA 850 performance. Coming from someone who got to ride the piss out of all 3 in one day for about 2hrs each. (Steep and trees) All 155" 2.75 RMK
@@Drew-in-NoDak No "well clutched" n/a 850 will outperform a 9r without significant additional mods...and even then it won't. Having both in my garage, the 9r is an entirely different animal than a n/a 850...incomparable. Your two hours is showing. As far as your holdover comment, there are so many '24 hold-overs due to the prior covid-related shipping problems solved in combination with increased production....and most people questioned Polaris' (and Skidoo's) ability to get sleds to the buyers. After all, no one wanted to get their"new" sleds in February.
I disagree with his statement that naturally aspirated gets the air in faster. A turbo literally forces it in so how could a naturally aspirate be faster? The engine sucking it in naturally versus being forced into the engine. The logic doesn't make sense. It's all up to the engineers do you want throttle response or big power.
99% of 9R owners would think an 850 was a 9R if someone changed the stickers. every single sled on the market now has insane throttle response. absolute marketing ripoff lol mountain = boost trails = 850
Donald Trumps 2 stroke v-16 Polaris boost engine is 850 CID per cylinder. It makes 13,500 hp @ 1150 rpm. Burning hydrogen and dry sump oil injected burning amsoil interceptor.
Maybe they could build less expensive stuff….. snowmobiles have been ruined with too much power and built to light to hold up, now most of us cant even participate.
Maybe Polaris should stop focusing on winning races, and start winning and reliability, and taking care of their customers. Polaris knows how to make a real good operating machine in all of their departments. Now figure out how to build a machine that can be at least as reliable as Honda and Yamaha. Polaris needs to have a better team that investigates these machines better, instead of selling them to the public and letting the public be the dumb guinea pigs.
Spot on. I’m a ski-doo guy have an 18, 23, & 25 renegade / MXZ Xrs the 25 is a turbo, i really really want to add a 9R XCR to my madness but i just can’t until I know the reliability changes. I love all snowmobiles🤟🤟🤟🤟

I am going to say none of the above and go Skidoo, sad to say both manufacturers are having to many issues but Polaris as a whole has way more!
9R. You guys are the best…..explaining in promotions and mind selections of Polaris 👍

Love em both! We sure are spoiled with options these days!
I thought of an OP 1800 R made from 2 9R engines like a Fairbanks Morse OP 2 stroke. It would have to lay down in tge chassis

What happens if you put the Turbo on The 9R ??
Love my 9r
What if Polaris made a 900 CID 2 stroke inline 6! That would be nuts
Very well said Nels
Divorced wastegate that’s what you get if you buy one of these and your wife finds out 30 grand sweet Jesus boys
That’s Canadian 😂 USD +/- 3k

Better find a better wife if she's telling u what u can and can not buy
Why not a supercharger for response instead of turbo?

Where can I get one of those hats
Should’ve included the 650 with this.
I'll take the one that doesn't require anti static juice, a retune, or 8 plugs a day
No worries - with the new ECU update you might get it down to 6 plugs a day!
@Fahren47 that's not good for my ngk shares 😵
@@zp9898 Hah, we were joking about that just earlier today in the workshop; that the CEO of NGK must send Polaris some pretty good christmas cards
What mpg difference is it with each? I'm not buying one of these. Just wondering. Thanks.
9r for me
9r sense I am at sea level and ride tight turning trails with not alot of open areas . I want light and immediate response 👍

I ride Michigan trails btw
Neither of those. No more stickers for me.
So many jealous haters in the comments lol.its actually so sad…buncha grown men too
7 percent increase in power for the 9r over the 850? Might as well just keep your 850 amd tune it out. Whats that, like 11hp?

Look at the tank of the exhaust on the boost. My goodness. And aftermarket can would drop is bet an easy 20 lbs

Polaris should 💯 solve their spark plug fouling problems before they make anything else.......
Try using br8es. Hotter plug and is approved by Polaris
First thing you start with is a Skidoo engine, then decide...🤣
