Ok so I have installed a TKI BD on my 14 Silber Turbo XM and have run it now for 250 miles. And WOW is this kit awesome!
The install is very straight foreword. In fact the included instructions are the most detailed I have ever seen. I am sub par when it comes to wrenching and I could easily follow the instructions and install this kit.
Each step in the process has been photographed and included in the instruction manual. Tells exactly what tool to use and included a pic of the tool even.
My only issue was getting the stock sensor cap out of the drive shaft. What a pain these are to remove. I damaged mine during the process but no matter because the kit come with its own sensor "cap".
What I really like about the kit is the ability to easily change the gear ratio. I went with a 2.33 but also picked up a smaller and larger gear.
The 2.33 really seemed to be the perfect fit for my SIlber turbo'd sled. The RPM's were floating about 400 RPM's before installing the kit. I was thinking I may have a clutch spring going soft but after installing the kit it held dead nuts on 7900 in the deepest of snow.
I am getting consistent 65 MPH track speed while sidehilling deep heavy snow. And it had a top recorded speed of 112 (probably while spinning track to get unstuck). It also increased the throttle response making it extremely "snappy" to my throttle inputs.
I did not do the "weigh the difference" thing but it is easy to tell this kits shaves several pounds...without even getting into that whole rotating mass thing.
Honestly I was a bit skeptical about the belt drive and its advantages. I had some money left in my build budget and was wondering where it would best be spent. After 250 miles I am really glad that I decided to go this route!
If you do go this route make sure to check deflection after the first ride. Not sure if the belt stretches or what but it needed to be adjusted after the first ride...but has been fine since.
