Those links are pretty good. Motorcyclist dynoed the 99 at 113rwhp back in the day and the top speed was 169mph. Not bad really.We all know dyno's read different on different days and dyno to dyno so............who's to say? 120rwhp is probably pretty close when piped and jetted correctly. I know mine was plenty fast. It would hold off a stock 954 from a first gear roll on through most of 4th gear and then it would get around me.
