Factory Polaris turbo ???

[greasemonkey3406]

By the looks of the amount of summits for sale on facebook I'd say quite a few ha.

Interesting bypass intake system. Must have some sort of check valve in the system so it doesn't blow the boost back into the intake. Too bad it doesn't have an optional race gas tune! Be cool to have 180+ hp at sea level option. But this may come later. I also heard them say that it's only a one year deal? Do you think they're just testing the waters?

Banks used a system of similar design for 20 years on twin turbo small block chevys.
At low power the turbos pumped into the atmosphere to help keep their rpm up. Engine vacuum controlled the dump valves. Now it is being done electronically. Tuners are going to love the new engine. If its reliable we will see them running boost at sea level on premium before long.
As long as it sells looks like the trend of the future. Personally I'd still be tempted to go the aftermarket route for gains at all altitudes.

They use an electronic valve to close it off but it's really not a new idea. I have a buddy that's been running a similar concept for years. But his is a passive reed type design.

But that Doo will be awesome for a non-wrencher. Which is basically your average Doo guy, right?

You know if you decide to switch brands some day you'll enjoy not having to work on your sled.

So true. My trail sled is a Doo. They just run. Unfortunately, the Doo mountain chassis ranks 3rd for performance in my book.

I realize it's a 4 stroke but Polaris has had factory turbos for years in the Rzr lineup. I think they have enough experience at producing and warranting a factory turbo. Interesting that both Cat and Ski Doo felt the need for extremely early releases. Hmm....

I ride 0-3000 so I have the choice of a turboed 2020 850 @165hp or a NA 2019 850 @165hp.

Let me time to think here...

Let’s be realistic here fellas..... 165hp Means this little guy is probably only capable of 3-5psi max. 165 is 165 at 10,000 ft. So is 220 on an 800 or 850 Axys with a boondocker. Price tag on these doos I can only imagine what it will be.... buy your own turbo kit and sled and your probably gonna be coming in somewhat close in price and getting way more power for your bucks. And besides nobody is ever gonna make a real turbo sled with warranty. It just won’t happen.

Good on these guys for leading the pack and putting one out there. Hopefully the followers will put a little more boost into their stabs at the market share.....Then again, a stock power level sled with the sound of a turbo might be a lot of fun too.

I’m biased I like big boost !

At 3,000 feet you will have a turbo w/ 165 HP or a NA sled with 150 HP. Not a huge difference for the lower elevation people, but some will spend some coin on other solutions for even a 10-15 HP gain.

The toons will come

I applaud Ski doo again. I'd love to have 165 hp at elevation. The motor is designed to deliver and run at 165 hp. The sea level guys have always had that benefit. Polaris and Cat would be foolish to not follow suit. Have it as an option for the guys that want to spend the cash but don't want to lose the warranty and fiddle with tuning their own turbo.

 

[Solby]

Hopefully they will have better than just 1 year engine warranty..... That would make me as nervous as owning my 2019 Patriot out of warranty. Very cool to see a factory turbo this is a great option for guys that want a pull and go setup. I would have preferred a narrower and lighter chassis, but to each their own.

 

[MKULTRA]

They literally said 1 year warranty

Having never run a turbo I've always wondered how much of a risk they are to the engine life. If the engine is designed to run 165 hp and all this low boost turbo does is allow it to run 165 hp at all elevations, is it going to hurt engine longevity that much? I'd be interested in the opinions of you turbo aficionados.

My 2016 axys is 200-210 hp with an intercooled mtntk kit and it has 2000 trouble free miles. I would never go N/A again.

I’m new to snowmobiling this year,(2020pro rmk 163 850) but I have lots of experience with turboed aircraft. In my application I run what is called a Turbonormalizer. It essentially slowly adds in Boost so that up to over 22,000 feet my 550 Cubic inch engine thinks it is still at sea level and performs as such. I think an engine loses 3% hp per 1,000’ elevation.
If an engine is rated to put out max hp continuously, then having it lightly boosted to make sea level power all the time shouldn’t harm it, as long as certain parameters are met. Overboost and preignition will kill an engine rapidly. Therefore I bet the new Doo is very tame in its boost and tuning.
Here’s to the new FACTORY TURBO power wars that are sure to ensue!

PS, my 850 hasn’t left me wanting more power yet, but I’ve never ridden it below 7,000’ feet yet. Maybe I’d be shocked if I felt sea level power for once.

Well welcome to the sport winshady and the forum. Don't ride your sled at sea level it will just cost you money.

Also of note.

Having never run a turbo snowmobile, you haven’t lived yet...........

Everything happens so quickly.

Call it riding a 250f mx bike vs riding a 450.

Interesting for sure but how many guys want to be a guinea pig / lab rat for the first year????

Well lots of 19 RMK 850 owners took that leap LOL.

Doo should have addressed the **** suspension and an update to the chassis beige any power gains. The G4 chassis is dog **** with boost unless you spend 4K on Suspenion.
