a friend want to line them up! *i have a 98 mach 1 clucthed w/ dynoport stingers, *he has stock 670 *each have same picks how much should i put down$$$$$

How far are you racing? You should have him in the short run as well since he isn't running the HO, but certainly the longer the run, the better it will be for you.

The Mach would win

well, having a 97 myself, I would say that the MXZ will have a chance if the rider is lighter than you. I have put my lighter cousin on my sled and he has beaten ZRT 600's by almost 200 feet. And that was stock! He weighed about 200lbs at the time. If the MXZ is hooking up, I would not rule him out of the winner's circle...in a long race though, the 670 doesn't stand a chance. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

DO YOURSELF A FAVOUR AND MAKE IT A LONG RACE AND TAKE THE YELLOW SLED'S OWNERS MONEY. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/smile.gif

not even a contest for the mach 1... take his money

Agreed, I owned a 97 670 and I never was able to take my friends 98 Mach 1. *It pulled harder all the way, at least I was close until about 70 Mph.

after you take that guys money, come on over and i will run ya 2-to-1 odds, with my 99 670 * *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif
