That sounds exciting ! :)
I miss riding a turbo sled for sure but the 850 has been a pretty good substitute.
If this goes on the 850, it should be a beast!!

We all knew it was coming.

Combing though those there is some very cool concepts and ideas the aftermarket has played with in the past. Giving those some OEM level support and development means we are likely to see a kit that performs far better then anything we have on the market right now.

VERY excited to see these hit the snow and throw a leg over one.

I'll give the DOO crew some props for being first to market, but a Turbo 850 axys platform (or most likely a maytrx) will be off the charts fun.We ar ereally in the realm of seeing ful mod sleds rolling off the showroom floor these days.

We all know cat and Polaris can’t wait very long to put out their own 2 stroke turbos. The Polaris patents have some very cool ideas. Not so sure about this belt drive pic from one of the patents. Can’t imagine that belt ain’t gonna slip with some turbo power. But what do I know, ain’t no engineer

There's a lot of information there. I just started to read some of it and it looks like they're hoping to put out 2-3psi at sea level, up to about 7psi at elevation! That'll be a big step up from the Doo turbo.

Also cool to see the reeds in the boost box. I have a friend that's run that concept for years. Had it in his Dragon chassis! Worked well to reduce turbo lag.

Holy s#$t guys, this is sweet! The belt won't slip, it's got teeth. But there's a reason that idler is there(Hopefully it's adjustable/spring loaded for easier swaps in the backcountry).

See that oval in the middle (#80)?? That's an exhaust tunnel dump!

We will see how much ends up in the production sled.
Isn’t something better than nothing?
My other hobby is airplanes, and “Turbonormalizing” has been a game changer for our piston engines at altitude. Aka making sea level HP at altitude. My 850 didn’t seem down on power, but then again, maybe I have no idea what I’ve been missing out on!

I think it's probably to run the exhaust through there, outlet is #80 as pictured above

Good catch! And smart of Polaris, but I hope they switch and put that idler wheel in front of the exhaust outlet. More teeth to belt on that upper sprocket!
