That being said there’s not even a single decent lap time from a catalyst on that score sheet so it looks pretty dismal so far. Lots of new stuff to overcome. Shocks, the ADAPT clutch is still fairly new, chassis, etc. I'll have to ask, but I'm wondering if Paul Brown maybe had the fastest Catalyst this weekend. 9 hours ago, fortune46x said: He won by a mile - a literal mile. From what I heard the skidoos were running 113-115 gps mph, and the cats were only able to get 105 out of the sled (they werent getting it to shift out fully) I can remember watching Tucker get off his sled and limp for the first few steps kind of hunched over as he walked back to his pits , it definitely takes its toll over the years. Getting to do some ECU work really has helped the Doos this year, apparently. Having Bryan and Betsy as your mechanics with Wes providing feedback helps a ton too. I think Bryan is probably the best mechanic in all of XC. Once I walked away, it probably took me a solid 2 years to get back to not having weird pops or sudden joint tightening throughout the day. 1 Quote Link to comment Share on other sites More sharing options...

And the limited test time with the weather we’re all having definitely killed their learning period. Glen Arlaud might’ve been the fastest catalyst too Quote Link to comment Share on other sites More sharing options...

Premium Posted January 18 Share Posted January 18 (edited) They're def going to need to figure out how to get more top end out of the Catalyst that's for sure. I wonder if any are considering a torsional conversion to try and gain some (not sure if that's legal clutching or not). I think I read that Paul was doing quite well until an electrical issue took him out of the stock race. Edited January 18 by Premium Quote Link to comment Share on other sites More sharing options...

Premium Posted January 19 Share Posted January 19 Zach gives a recap at the end (7:28) and basically says they haven't found the top speed they need to be competitive. Hopefully they will find an answer! Quote Link to comment Share on other sites More sharing options...
Premium Posted January 19 Share Posted January 19 (edited) I'm not sure what is allowed as far as changes in the stock class, but I know the Polaris Cross Country sled runs a 2.52 pitch track vs the Cat's 2.86. There's going to be a definite top speed advantage too the 2.52. The R-XC also appears to use 8 tooth extrovert drivers...going to larger involutes would def gain mph too. Maybe they've already done this. Edited January 19 by Premium Quote Link to comment Share on other sites More sharing options...

There are many threads of guys documenting improved top speed numbers with larger drivers and 2.52 pitch tracks. Lots of stage tuning back in the Firecat days. Hell I gained major speed with my 04 F7 by going to 10 tooth drivers from the stock 9 tooth, accounting for gearing too. Some guys were even putting their involutes in a lathe to true them up and picking up mph. I agree the R-XCs have long been 8 tooth, mine included....mine has never seen above 97 mph either....

I agree the R-XCs have long been 8 tooth, mine included....mine has never seen above 97 mph either.... current issue imo is they're not getting 1:1 or full shift with the clutching, gearing and drivers they're running. I have a bunch of opinions why already spelled out in the Catalyst Chassis Thread. for max velocity on the lake I do wonder what a 2.52P 1" lug 14"w speed track would gain them? had one on the 720 and hated it for trail riding BUT I can without a doubt say with confidence it spooled up much faster and more efficiently, easily had a higher top end and you could tell it was moving less air inside the tunnel. it's also part of the reason I believe it overheated and cost me an expensive engine. but, going back to the 500 racing days if my memory is correct... fast racers were running the speed tracks and a bit steeper than stock gearing and clutching. will be interesting to me to see if the GD Soo mods and MIRA sleds are short tracks again like in the past... anyone notice if Bunkes rocket was a 128 or still a stock 136 as comes on the 600R? 1 Quote Link to comment Share on other sites More sharing options...

I think the Doos are 2.86. Aren't they also all single ply from the factory? Yeah I'm sure the clutching needs to be dialed in. While the primary idler bearing system works great for the average rider, I've always wondered if the constant compression secondary acts to prevent overdrive. For all out speed it's hard to beat the old Cat reverse cam button/roller secondary setup. They just work.

For all out speed it's hard to beat the old Cat reverse cam button/roller secondary setup. They just work. team clutches have always sucked for top speed, and acceleration (drag racing at least) the old reverse cam would work fine with the idler bearing, as long as you don't mind questionable or not working engine reverse. One thing the idler bearing does do though is change the "gear" ratio of the clutches, and increase belt speed at the same ratio as a non idler bearing clutch 2.86 track SHOULD turn easier, and have less resistance than the same style 2.52. 252 hooks up better drag racing because you can load more steel into it.
