I am by no means a Ski Doo expert. From what I read on this new 850 summit turbo, my understanding is that with its design it allows riders at high altitude, i think above 8000ft to not lose any power as they would with a non turbo 850. i believe the turbo does nothing for it unless at altitude. Like I said I am no expert on this. Maybe I am wrong. No where I saw says it makes it 200hp. It just compensates for the loss of 40hp yiu would see above 8k feet. from an article on the release “Riders will enjoy every ounce of the 165 horsepower from the industry's leading 2-stroke engine to its fullest, all the way to 8,000 feet (2438 m) in altitude. They continue to enjoy a 40-hp advantage over non-turbo 850’s from there up on the way to discovering stunning new winter playgrounds.” Fozzy, dooright and mikerider 2 1 Quote Link to comment Share on other sites More sharing options...
zeusand Posted January 16, 2020 Report Share Posted January 16, 2020 That's what I read as well, just doesn't lose horsepower in high-elevation. But still, how do you add a turbo and not gain horsepower even at sea level?? Quote Link to comment Share on other sites More sharing options...

Beats me I put gas in turn key and ride it probably computer programming. zeusand, GSX800 and PINKM1 1 2 Quote Link to comment Share on other sites More sharing options...
mikerider Posted January 16, 2020 Report Share Posted January 16, 2020 Sled has an altitude sensor. Kicks in when gaining altitude by sensing thinner air, instead of loosing 3 HP for every 1,000 feet. At sea lever turbo won't kick in. So at 8000 feet, Doo is still making 165 HP while other 165 HP sleds are now running at 140 HP. iceman and zeusand 2 Quote Link to comment Share on other sites More sharing options...
iceman Posted January 16, 2020 Report Share Posted January 16, 2020 It’s useless here in Quebec. Not gaining anything with it. Anywhere on east coast for that matter. No Hair 1 Quote Link to comment Share on other sites More sharing options...
Shore1066 Posted January 16, 2020 Report Share Posted January 16, 2020 I agree about it is for high altitude. What I read was 165 hp at 3000 ft and 165 at 8000 feet. Mine has enough moving parts to worry about so a turbo I don't think I need. Only my opinion. Great day tomorrow, my oldest boy and a couple of his friends are headed for Mont laurie and then north. No plans yet for a sleeping spot. Going to be a good time. Quote Link to comment Share on other sites More sharing options...
Blueblood Posted January 16, 2020 Report Share Posted January 16, 2020 I believe the turbo only spins up to 4psi. So that's why after 8000 feet it starts losing some horsepower. But best part is pump gas and a warranty. I agree waste of money on the east coast. Quote Link to comment Share on other sites More sharing options...

We are heading up to Mont Laurier to start a western trip on the 31st. Hope to see you in the restaurant or better yet, on the trail soon.

quebec bob Posted January 16, 2020 Author Report Share Posted January 16, 2020 I saw the 40 horsepower part and assumed that would be in addition to the 165 , thus 40 plus 165 is 205. What a waste to only have it at altitude, but by next week some tuners will probably be available to fix that problem. I am still hoping this has a future in a trail sled, say a 146 mach z gen 4, a little lower than a back country with 2 inches wider ski stance, to compete with the side winder, it would make sense dollars wise because I think the mountain guys will be eating this thing up.

It'll never happen, no way to run it on pump fuel at sea level, couldn't warranty it 800steve 1 Quote Link to comment Share on other sites More sharing options...
MrGutz Posted January 16, 2020 Report Share Posted January 16, 2020 It may happen, but not completely the way we would want. I would predict a timed over boost\boost condition, I believe Ferrari and Porsche have used similar ideas as well as Polaris on their Dragons. Like launch control, available for short distances and very tied down, ANY thing out of sorts it would not activate. This could allow for Very Powerful Launches or Mid-Range to Top End Pulls, but shutdown if it senses any out of band results. Just my thoughts.

From the couple of times I've been out west I'd lost and needed compensation for a lot more than just HP up there!

So this turbo starts working at 5oo ft. There will be a very noticeable side by side difference, I know it is only 4psi, but who knows at what volume, the intake and pressure tubing look big.

Stan, I just sold that sled a week ago, that was the very first Yamaha mountain performance turbo for the 3 cylinder Yamaha engine that Mac Randolph sold. I ran 7.5 psi of boost, on pump gas, basically 200hp, and a four tower clutch, 10k trouble free miles, and never even had to change a spark plug. Also never lost a race to anyone, that was a really fast sled and a ton of fun, and the fuel mileage was 16, it was really impressive on groomed trails but not very good on bumps. Now I have a expedition extreme and a 850 backcountry, certainly no where as fast but handle a lot better, hope they turn out to be as reliable as that old Yamaha, hope all is well, Bob. zeusand 1 Quote Link to comment Share on other sites More sharing options...
