Are you guys ready for the next skidoo game changer?

[MOMMA]

yes. spread the word.

I'm starting to wrap my noggin around this


ooo Maxewell sent me a wicked expaination. K we lose 3% hp for every 1000 feet, so that 30% loss should have been for 10,000 feet elevation riding not 8,000. Sean explained to me that "It ALWAYS maintains 165 hp. Only after 8000ft it stops building boost so it will start going down after 8000ft. But from 0-8000ft it will always be 165HP"

The world has been waiting. Ski-Doo has delivered again, with the first-ever 2-stroke turbocharged engine in the Rotax 850 E-TEC Turbo. Perfectly melded with the ultra-agile REV Gen4 platform, the Summit 850 E-TEC Turbo delivers maximum power up to 8,000 feet and continues to deliver 40 more HP than naturally aspirated 850-class engines as the ride climbs higher in elevation.

Maxwell I sent you a message on FB. I'm curious, and some people have tried to explain this to me. So what I've heard is the turbo doesn't kick in, and over ride the ecm until 8000feet where at that point it will kick in to compensate for the horsepower loss at 8000 feet (30%) to keep it at 165 horse at 8000 feet and up elevation.

Is this how it operates? We typically ride at around 5000 - 6000 feet on the Kootenay Pass so this would really eliminate the sales demographic that doesn't ride at super high elevation.

Can you explain. Thank you!!!!

It has the ability to take intake air at low throttle from an actuated bypass.

This allows it to maintain a stock throttle response before the boost starts to roll in, should be more seamless than a average aftermarket kit.
Thiñk side wiñder.

It will compensate as you go up in elevation by adding boost so you always have a full 165HP.

Only up to 8000ft because as the air is less dense the turbo won't be able to pump enough o2 to supply full HP.

You will have less HP loss at 6000ft for sure, something to take into consideration.

bah...what a killjoy he is

They have been testing at ckmp for two plus years, thought it had a different sound

Remember when the 17 G4 came out and Carl said they had been testing them for two years......

FYI boulder mountain CaBiN is 5400 ft... Average riding elevation is 6000ft so a stock sled with 165hp of any brand will lose 3% per 1000ft so this means a stock sled with 165 hp will only have 137 hp but the new summit turbo will still have 165 hp even at 6000 ft and up to 8000 ft after that 8000ft it will start losing hp based on the new summits turbo settings ... So the big benifit is your getting a intergrated manufacture turbo sled with warranty with 5 - 40 hp gains at between 1000 to 8000 ft average elevation riding against a stock 165 hp sled that's loses 3% hp per 1000ft of elevation ...hope this helps

 

[skegpro]

Serious question.
Can you grill steaks on the thing?

 

[neilsleder]

wow im impressed chris. That must have been really difficult to do. LOL. new year new you

He was throwing up a bit while typing that

K it's all good, Maxwell helped me with the math! cool concept for sure.

 

[NoBrakes!]

So what yer sayin is... She chews?

143.5 hp

Ahaha I was gonna post this exact same thing but decided not to.

Yes, I remember that clearly.

 

[Clode]

bold move ski-doo, I guess we will see how they work

 

[skegpro]

When is the Polaris release Momma?

 

[snochuk]

I’m happy to see that they adjusted the pricing for the Canada dollar. Will place my order for a unit in March at snowcheck

Will be two maybe three of us snochecking.....there will be a lot of turbos on the hill next year!

you better not start an angry thread if it has issues

Turbos work by pressurizing the intake they have a turbine side, and a compressor side tied together with a single shaft. The exhaust spins the turbo and in turn spins the compressor that supplies air to the engine.
At sea level the ecm will tell the turbos wastegate to maintain say .5psi to keep the sled at 165hp. (Wastegate is a air bypass or dump, and it control boost levels.
As the air thins the higher the sled goes in elevation, the wastegate closes and the compressor wheel starts building more pressure in the intake charge tube to maintain a certain amount of HP. This in turn builds more HP in the engine.
Unfortunately saying that a turbo maintains its HP is kinda not true, they have limitations and can only pump so much air.
If a kit only makes 5psi at altitude and you take the sled to 12000ft than the engine will loose HP. “If it can’t suck, it cant blow”.


Im trying to figure out if doo will release this sled to the eastern low elevation guys. Kinda pointless to spend that money on a turbo to jave the same HP as a Natural aspirated 850.

 

[pano-dude]

I love how ski doo does there R & D... pay 26g for a sled that may or may not work lol... seems alot cheaper to by a pro and slap a side kick on it. And at least you know it works

Ha, polaris never had any issues in the past eh?

 

[yamiklr]

when can i get a lighter can for this?? louder the better . lol

I hope so. My ‘17 G4 is an amazing cooker (stock exhaust). Looks the the panels the same down low (same exhaust cooking area by judging the looks of the panel). Might not be able to cook in the deep stuff though with the snow cooler that they put on it. That would take the fun out of ‘give me 15 minutes to cook’ for the crew.
