gear shift and the dyno

Joe,

The way I do it is to determine the RPM drop going from 1-2. Then look at your Torque curve to find the peak and also see how flat the curve is around the peak. I take the net rpm difference and overlay that around the torque peak to try to take as much advantage of the flattest part of the torque curve when the engine is recovering from the shift. For the 2-3 I would run the car out closer to the HP peak using the same RPM Drop philosophy.
