Since winter's approaching here in Seattle, my gearhead brain has clicked over to snow machines for adrenaline fixes. If you haven't been following, they've gotten ridiculously light and amazingly powerful in the last 5 years or so.

These guys, Mountainperformance.com, have kicked the bar even higher with their kits. Stage one gets you up to 230 HP, stage three is capable of 350+hp. Yeah. Granted, 8 grand is a lot for the full kit, but... 350 HP!!!!

Did I mention - 350 HP?

Three hundred and fifty horsepower.
