Here's some information from my trip last weekend regarding the XC700. Here are the sleds, and what the mods are...
2002 XC 700 SP
: SLP bottles, 96 studs, Reeds, clutching unknown.
2003 Firecat F5
: 360 mains, 58-51 helix, stock 1" track, air/ fuel tuning as per ArcticChat.com. (thanks guys)
Here are the results on a hardpack groomed lake trail:
: F5 wins handily... absolutely killed him on low end. It seemed like the XC couldn't find any low end grunt to get it out of the hole.
Lake race to 60mph
Lake race to 100mph
: XC made some gains at higher speed, but still lost.
Because it was a friendly race, we switched sleds for about a half hour and did some river riding. Without getting into a Polaris bash-fest, I'll just say that I was disappointed for my friend in both the suspension/ handling and power aspects of his sled. I think he, after riding my Firecat, was disappointed as well. While I don't suggest that these results are indicative of all races between these models, these are my results, and I'm damn happy to report them!
