The newer 600 and 700 sleds absolutely rip, and the IQ6 does too, but my longer track with the 1.25" ripsaw allows me to pull ahead of the more powerful and lighter 2 stroke sleds with lesser tracks. By the time we hit 80 I am usually 5 sleds ahead of my cousin's IQ6 (I think it has a shockwave track?) and then we seem to just stay the same length apart past the century mark. I was probably 10 lenghts ahead of the F6 (2004 non sno-pro), but of course we were racing on an open rr grade with looser snow and not a hard, flat road so things could turn around in different conditions. I am sure under ideal conditions both sleds would pull me on top end. I haven't been able to top the 108mph mark on my speedo yet (about 95mph gps). That was on a pretty hard trail, but I was also over-reving by about 500 rpm on top end which may have hurt my performance somewhat.

M-Cat - well you're clutched too plus a few other goodies.
I've yet to see a stock Vector "beat" an "in tune" 600 or 700. There are exceptions of course, but if you buy a stock Vector and expect to always beat 600 and 700 class sleds, you will be disappointed.
