I am nowhere near the speeds that some of you guys are getting but I was very pleased to see 119mph on the speedo when I let off racing my brother-in-law this past Saturday. I wasn't trying to see what I could get for top speed but that is the fastest I have ever seen on my sled and fastest that I have ever been on a snowmobile. The sled is a 2017 LTX SE with TD PowerTrail tune, TD 3" Super Quiet exhaust, TD CAI, and all Thunder Products Clutching w/ XS825 belt. I also have a Vector primary clutch that Thunder Products cut for overdrive before this season. This setup runs right at 8900rpms. I am very happy with it and I don't really want/need to go faster.

Wow, I can’t wait! Just trying not to hammer on mine too much as she’s brand new, ‘22 Winder LTX GT, TD Multimap, 2.5” Turbo Force muffler, Dalton weights, BOV, 3-bar map, still trying to figure out how to install my CAI as I believe I bought one to fit under hood from TD but there’s no way it fits and I’m not cutting out to stick up through so will be calling Mike today. Still figuring out the whole clutching thing as I’m sort of a newb… was hitting around 105mph with WOT at exactly 9000rpm in 7” powder on the lake Sunday, but yesterday I just played on the trails a bit and didn’t really check speed as it definitely gets there fast and the straightaways don’t last long. Lol. I noticed that I hit 9450rpm at some point, so adding some weight to the daltons today and hopefully can get CAI installed so I can switch from 250 Ecotrail tune and give the power trail and MS17 tunes a try! I’m not so good at using the forum yet, so hopefully can learn this too as it would greatly help to have more input to assist with tuning and what to watch for so I don’t destroy my machine.

Don't go by the recall on the gauge. That is a worthless feature, it will hit a hi RPM on a spike and the spike means nothing. Even looking at the tach is just a moment in time, but much better than using the recall. Logging will tell you the story, but using the tach if you don't have logging to see the whole story, is the next best way to clutch.
