| (6) It will be noticed that one period is about 800 X 3 per rev. = 2400 - i.e. torque reaction, and the high one 65/70 MPH. probably 1 per rev. = 2500 revs. For several years I have thought that the torque arms should be as far forward as convenient - i.e. away from the body, and direct on the front springs, which are damped - i.e. not on the flexible part of the frame - I mean vertically flexible and undamped, as it is under the dash. I cannot believe Bentley should be better than we are except the flywheel whirl, which should be improved by modifications. R.{Sir Henry Royce} | ||
