Clutching gearing 136" M-10 Viper Ripsaw. I've got a 02 Viper with King Cobra kit and I'm trying to get the clutching and gearing dialed in. Since the Viper mountain runs 21/40 and it's a 144: track I went with 21/39 gearing with heavy hitters and a multi angle helix. It pulls hard out of the hole to 8,200rpm on an uncalibrated tach and creeps up to 8,500. The top speed yesterday on my GPS was 85mph 97 on the speedometer. Does this sound reasonable for a motor that is supposed to make 135-40 hp. I know the M10 robs power but this much I figured it should still run out to at least 100mph on te GPS 112 othe speedometer.
