I did some tests using a shock that has wear. I do not have a spare shock that has no wear. I used 4 different fluids, Water, 10-40W, 140W and "600W" oils. I tested with the needle valve closed and with it open 2 turns. I found that I could not get enough resistance because the shock was too worn. So I repeated the tests this time after plugging the lower bypass hole in the rotor. The values in the table are foot-pounds. I estimate that the weighed arm in Ford tests exerted about 9 foot-pounds on the shock. My tests are torque values not timed drops as Ford did. You can draw your own opinions on the results.
