2009 American Snowmobiler/ DTR Adirondack Shootout sleds

[Pages:10]2009 American Snowmobiler/ DTR Adirondack Shootout sleds

Here is the prelude to Shootout XX, all the stock sleds selected by AmSnow and provided by these Adirondack area dealers: Smith Marine SkiDoo, White Lake Polaris, Ed Fredericks and Sons Arctic Cat (took the place of Big Moose Arctic Cat after last year's Crossfire 1000 cheating debacle) and Excell Yamaha of Utica NY (took the place of Big Moose Yamaha after they chose to quit the Shootout after their Cat division was set aside).

Here they are, in order of displacement. Note that we used an Innovate LM1 wide band O2 sensor to measure A/F with a probe inserted into the muffler outlet. At low revs, WOT, there is some reversion that sometimes draws outside air into the muffler which causes leaner than actual readings, but at high revs readings are good. Where it was practical and easy, like the non-return Arctic Cat EFI, both LM1 and mechanical readings are provided. Note also how lean the Rush is at WOT. This is the second Rush tested here, and the LM1 and mechanical meters indicated similarly lean mixture on that one as well.
