Yes they seem to be about 10 hp high if the Turbo G4 only had 165 hp.

Thats what mine had when it was dyno’ed so it matched BRP’s claim. So until we see a honest dyno of a boost thats not on a bikeman dyno, I will believe doo’s claim when they put a boost on their dyno.

Same dyno for the Boost was 195 hp.
does 195 seem realistic from anyone that's ridden one? that's an impressive number.
Certainly does not seem like 195 is getting to the snow. Or they are heat soaking early and backing down?
You are correct. Keep digging and solve this mystery(kanedog cryptic hint, muwahaha)

Boost on doos was 172hp, the boost I rode had a tune in it. Definitely felt lacking on the top end, compared to my G5 at 180.
Anyway this is a Chaincase thread.

brp was well aware of the Chinese chain case components very early on in the season . Not sure when parts will be available to do the update and from my understanding it’s an inspection of parts not guaranteed they will replace anything.
I guess we can just keep cranking the chain tight as that’s a normal practice
These sleds need the tki fix or a solid shaft to be reliable IMO .
I put solid shaft and hyvo gears and chain in my 23 and after the first stretch of the chain I haven’t had to tighten chain again all season.

On Bikeman dyno 2020-2022 etec 850 turbo made 178hp, wich is 13hp more than Doo claims. They either cant properly operate their dyno or its calibrated wrong, who knows. But their results are unreliable and have allways been.
Ive ridden 23 Turbo R side by side with Boost, and dont get me wrong Boost is a good engine but no match to Turbo R. Response, power, torque Doo wins every category and wins all the pulls.

All 2023 Turbo R deep snow sleds will get new BW Hyvo chain and sprockets, period. Dont get fooled by your dealer. Parts should be already available in most areas.
That video is a nice overview of the separate possible issues. FWIW I have a 22' N/A that I blew up the lower gear in. The 22 had the one-piece driveshaft but the weaker lower gear with the holes in it. Found a used solid gear set off an older sled and hoping that solves my problems for the future.
The dealer will immediately inform you warranty expired and proceed to charge full pop for new parts, three month backorder plus $25 for shop supplies. Haha

Great video. Is it just a chain and bottom gear ? This would mean it’s not a hyvo chain I guess ?
Ok well that’s a nice upgrade, good job brp nice they come clean and stepped up to the plate on this .
