Seen CG in a a gig here in our city, was great. Yvon from the Race Dept made a bunch of them and I asked him for one and he said take a picture and make your own. So I did and its better, lighter.
Hi Alexbenoit8635. The engagement speed is chosen by the calibration development team, which outside of the engineering techs, consists of "Ski-Doo Riders" like Kuster, Rasmussen, Chaffin, McNolty, Mantaberry, Mercier...etc. When you have riders that some come from a background of racing sled use, [and from other brands that used turbo sleds with engagement speeds higher than 4000 rpms] then along comes the "baggage" of 4000 rpms engagement speed which are added into the settings. Even though the turbo compensates, inducing the engine to maintain a natural aspirated tendency, the engine still loses a little bit of bottom end torque as elevation increases. To help push through a possible lag condition as elevation increases, the tuner can raise the engagement speed. Raising the engagement speed helps the engine "Rev up" through a lag situation. Here at iBackshift, we try to overcome possible engine lag through other settings in the clutch setup. I like to get the engagement speed to 2900~3000 rpms and use other means to get the engine to rev to 8 grand in an acceptable manner.
Man other than the turbos and 4 strokes. Sleds havent made much progress in the last decade. I think a tricked out 97 to 03 summit with a similiar track lug I don't think they were at 3 inch yet. Could compete ad keep up no problem. I think it's more of the creature comforts that have made big advancements. But electro digitals are a pain in the ass anyway. Cool tool tho. So 8100 rpm is it nowadays for a brand new BRP? I thought them 2 strokers where well over 10k by now
First time I'm seeing this holder tool Joe - I'm havin' it ! Also note something I've seen for the first time on my new 23, re-assembling the primary and the ring clip not being fully seated to secure the spring will cause the EXACT same condition as the cushion failure you displayed. Luckily I caught this during the first start up to run it up for a re-torque. I can only figure the ring wasn't fully seated on the backside on re-assemble, although the two "ends" were seated in the recess - just in case anyone else runs across it - double check that ring clip !
Also have seen on a brand new pdrive is the spider spring cup in the bottom, pushed right out of the spider. Buddy had to get a new spider under warranty...brand new sled.
Your power peak rpms are wrong. The 850 engine makes 165hp at 7900 AND 165hp at 8000 rpms. The difference between the two is at 8000 rpms, it 1.6 pounds less torque. The 180hp turbo has a flat power peak , 180hp at 7900 AND 180hp at 8000 rpms. The difference between the two is at 8000 rpms, it 1.8 pounds less torque. MY dyno sheet is from Skidoo from their Eddy Current dyno. All aftermarket waterbrake dynos do not show the same power curve as BRP Eddy Current dyno. One of the rare aftermarket companies that has an Eddy Current dyno is HSK Racing in Norway. HSK Racing comes up with the same power peak rpms as Ski-Doo. The Eddy Current dyno is the only dyno that comes close comparatively to the real world environment. The way bikeman, and jawz and dynotech all these other guys with their $100K watebrake dynos take reading on the engine power does not reflect what the engine will do in the real world. Its one dyno operator racing another dyno operator; its as simple as that. If you try to clutch an 850 summit to run at 77~7800, I can promise you, you are going to be stuck.....Lots ! ! !
People just can’t leave things alone. Besides a bit of turbo lag which isn’t an issue at all my turbo summit does fine at 12,000 ft with the stock settings. If your in deep powder and or climbing your already into the boost and beyond the turbo lag.
Comming over to a lynx from kitty cat land, on my demo ride that was the first thing I noticed. Nightmare high engagement. You mention getting the sled to spool quicker through other means, what do you recommend ? I'd like to get my clutching dialed before I even take it out first rip this fall. Cheers 🍻
Hi joe I’ve got a 2023 turbo I will be ordering your kit I’ve hade your kit on my last 3 sled. Just want to now why do they have such a high engagement from the factory what dose it do for the ride ?
Hey Joe.. waiting for the clutch kit to get here (should be Friday).. what is the best redneck way to hold the pdrive clutch when doing the arms and taking the cushion off. I don’t have that fancy tool you made up that uses the holder in the vice.
