When I run up my 2108 VW on level pavement, the nose will dip down and the attitude gyro shows the number of degrees. Shut down I hung weights on the crank shaft to get the same nose down pitch. Using similar math as for the weight & balance measurements, I calculated the thrust to be 203 pounds at 3080 RPM static. That measurement is prone to some error in duplicating the pitch angle on my gyro and the geometry measurements. The force gauge as used in the video is more elegant, probably more accurate and does give a direct reading.
