NEW VIDEOS: 2017 Ski-Doo P-Drive Clutch, Engine and Forged Crank
- Thread starter Norona
- Start date
Very well done skidoo!! so much innovation here its crazy!! cant wait for next winter
The innovation that BRP is pushing is purely amazing! I almost feel obligated to snow check a new 850, purely to support the pioneering of the snowmobiling industry they are doing.
A CEO mandated order, to design a new engine that is as reliable as a 4-stroke but still delivers the power to weight ratio of a 2-stroke is some crazy forward thinking! I thought it was a "pipe dream", but it looks like they've done it if this new engine lasts twice as long on their stress test dyno.
Way to go guys, way to go!

In the parts catalog it's showing the same.

I am typically not easily impressed...but the motor and clutch technology is really forward thinking and flat out amazing. The potential is huge. And even better is the rumor that they almost released it a year ago, but held off. That means a full year of development and tuning on this stuff. They really raised the bar on this sled. Id say this is the equivalent of major earlier innovations such as power valves or fuel injection. Super cool.
"One piece solid crankshaft" ???? (second video)... I'm sure the engineers were wincing at that one... 
More power from the stator...but less magnetic drag?? The physics don't seem to work for that... (I could be wrong... and would love to learn how this is possible?)
The Armored ring lands seem like a great adoption for this engine.
Dave, thanks for posting that up!!
I may sound like a "doubting debbie"... but I'm actually excited about this motor.... It seems like an engineering marvel.
Austrian designed/built??

You can have a lower drag stator by using more efficient winding density...thus allowing a smaller diameter stator or less magnets for the same volume. One can ger better winding density through thinner insulation or square wire. Less torque needed for the same output...which means less drag.
I believe the way it is indexed, it will not work, but I do not know for sure!! I will check!
Thanks, yeah it is hard to get tech guys to do this, but I have known Rich for a long time and when i asked him, he just did, these were one takes that I did with him. I am always trying to get new stuff, sometimes it works sometimes it doesn't but so glad i got these...dave
Increasing efficiency makes sense...did a quick google search on the square wire .... thanks for the lesson...'hairpin' design etc...
A smaller stator would also mean a smaller rotor = less mass = less inertia.
One of the things I like about this site... lots of experience on here.
