Take a look at the 98' MXZ 500 Dyno results in the November 1997, American
>A buddy of mine picked up a (white) zr 600 EFI. He put it on a Land and

Did the Doo F-III and the 2 ZRT's red light.? From the appearance that Arctic
Cat made at the Frankenmuth, Michigan Grass Drags I would have to believe that
is the case. In the finals on Sunday it was all Ski-Doo. The SRX700 Yamaha
even got smoked. I can't wait to see the results of the Hastings, Michigan
That is sad if that ZR600 only dynoed out at 105. They took a brand new just
out of the crate 98' MXZ 500. It hit 94.5 CBHP (Corrected Brake Horsepower)
from the 96' Formula SLS that Dynoed at 89 CBHP, isn't it.
Sorry the ZR's are nice looking machines but I will take the Ski-Doo.
Ski-Doo F-III and MXZ 440
