That is not correct. The 7* is at .050 lift. Can easily check the other degrees, just add the numbers and add 180 and you get the 224 and 230 numbers correspondingly. And, how can you explain a rumpy idle at 7 degree overlap at .006" lift?
Still curious about the massive torque. As friction takes appx 5% of the efficiency I guess it must be something else than minimizing friction that relieves all this torque. Do you use a vacuum pump?
