I agree. The transfer is so much FUN! Reason #1 I liked the Doos and Poos so much on trails. Its not hard to limit it for the rivers and lakes. Definitly gains speed. Tough to get a perfect balance between the two for sure though. All depends on conditions and the person riding it. For me on trails I would rather be happy at end of long day of riding when trails are shot than fast at beginning.Mike it has everything to do with where you ride primarily....
Obviously for any hi speed riding, groomed trails, or hi speed cornering ect.....the flatter sled with less transfer will be fastest. So I agree with you 100% there.
But when you hammer through a whooped out trail that is littered with trail moguls, the quick transfer and nose lift becomes a total MUST. You need instant response(QUICK SPOOL) and good transfer, to time those knolls, otherwise you land in the hole..lol
I recall a 17 winder with a horrible tune, I worked on that thing all winter and the tuner kept saying it was the most powerful tune available then. I swore I thought that sled was sick, it would fall into every hole after each knoll. Gave up on that tuner and went to quickest spool tunes(as you recommended) and voila! Now the nose lifts off each knoll and I never land in a hole.
My 1200NA did this perfectly with iTC and only 145hp or so. For me I want all the transfer I can get, it comes out harder and I am an active rider, so I have no problem hanging off to keep things flat when running speeds.
I think the doo will be a perfect little turbo for what it is....Stick that at 190hp tune and it will rock, Watching the early videos, the iTC is instant, since the little tiny turbo is literally mounted to the manifold/engine(close to cylinders) it seems the spool time is pretty much zero.
Dont get me wrong guys, it is no winder buster....but with its 40 to 60lbs weight savings below ours(depending on which model) And with a 190ish tune, I can see this sled being the next step down/below us....Since it will clearly be beating up on all the big 2strokes.....heck even stock it looks like the 850 and 900t are side by side.

The better one is spending $3500 + clutching to get to 200 hp and dealing with the POS MPI stuff. I've got around 2k into getting it to 290 and it's bulletproof.

Is this skidoos 850 flash to pass button dyno tech is testing lol
A scary 184hp lol
The one second throttle delay on the turbo ace doesn't sound appealing....

Kudos to Hurricane Dave just got the BRP 900t off the dyno....
Solid 30hp Gain, and in True Hurricane fashion applying big boost down low. Inventor of the Early spool tunes.

That thing is runnnung 16.5 psi of boost at 195 HP.
Put that same amount of boost into the winder and you add 80 HP onto that 195 number.
998 is a real bad #*$&@ motor for sure!

The Winder has 10 more horse stock, than that Flashed Doo has with a 30 HP bump.

Yep, and check out the a/f. It needs to be richened up a lot compared to the stock pull.The Winder has 10 more horse stock, than that Flashed Doo has with a 30 HP bump.

Having said that, the stock setting doo should be good on fuel as those stock a/f numbers are impressive. Many consider about 12.8 to be ideal for max power on a naturally aspirated engine.

The Minni z will make the 850 guys cry then the Minni z guys will cry when they try to run a tuned sidewinder.
