The 2008 Torch range should be similar to the 2007 Torch (changes for 2008 on kite are supposed to be minor). You can find the 2007 specs on the Naish website at this link:

Look for "Wind Range"
I owned the 8, 10, 12, and 14m 2007 Torch and weigh about 180lbs (82kgs) and found the numbers are fairly accurate using the shift bar (you may be able to get more upper range with the double depower bar). I would add 1-2 knots to their low end range numbers for my size (especially on the smaller sizes low end), these numbers look a little low. The upper end looks about right.
