T-Cat 1300 (Limited Production Sled) 115 mph stock.
T-Cat 1000 108-110 mph stock
V-Max 4 800 105 mph stock
I would have to say though, that the V-Max 4 is the easiest sled to get ridiculous power from. Getting 180 hp out of a V-Max4 800 isn't that difficult. I guess that's one of the pro's of a 4 cylinder 2 stroke.
I took a 2007 Arctic Cat F1000 2 stroke for a rip this winter. Blew the doors off an F7 like it was standing still. That F1000 was tuned and chipped and would do 108 mph on radar. So your VMax4 should even run well against the new big iron. Apparently the F1000 will take the T-Cat 1000 on the low end, but the T-Cat would creep away on the top end.
That was the only problem with the Yammies......the suspension was/is always a full generation behind the competition, therefore, they tend not to hook up as well off the line as another companies sled of the same year.
