My question is about horsepower! I am one of many who have been up to the big bores and are heading back down. I came to the realization last season that I am getting old. I’ve run my ’88 650 Wildcat for many years and loved it. I purchased a ’91 700 in my search for lighter and more trailable manners. This past season I broke down and bought a ZR 600. Although I’m not overly concerned about total horsepower, I am curious as to how they all compare.
The ’88 650 Wildcat produced 105 hp at 8000 rpm, and the ’91 Wildcat 700 was up to 113 hp at 8000 rpm. The ’98 ZR 600 was said to be producing 105 hp, but most of the dyno numbers we’ve seen have been in the 98-101 range at a higher RPM of 8300-8400. What is more important is the horsepower to weight ratios of these sleds. Even though the smaller displacement ZR 600 has less horsepower, it is so much lighter that it will outrun stock Wildcats.
