Doo claims that the new MXZ Renegage 1000 is thier fastest sled yet, therefore we have to assume that it would beat an older Mach. By the way, sleds are all BONE STOCK, 1000' run, Ideal surface. And for you americans, the speed is in km/hr. 168.22 km/hr = 105.14 mph. The 05 MachZ 1000 wasn't even in the runnings. The T-Cat 1000 would have beaten them all if it was entered.
And Big Joe.....no offence, but if your sled was stock, and the T-Cat was stock, the T-Cat would have had a good 10 mph on you. Well.....unless it was the 900 you were running against....then it would be close.
BUT.....the bottom line is this......You can be on a Mach, VMax, T-Cat.....it don't matter, but if you don't know how to drive, I'll beat you on an old 67 olympic.
We always debate on which sleds are faster, when we always forget to include the FACT, that even some of the most experienced riders out there, can't TRULY handle ALL of the available power of some of these big iron sleds.
