My explanation of "Eating Flywheel" has nothing to do with balance. It has everything to do with exceeding the Free play angle. I am not getting surface deflection of vibration. I output a fraction over 290HP and 287 FT/PD torque at the rear wheels. When the springs start to degrade I can feel the excess angular deflection as the cam timing fully advances under hard acceleration and sometimes shifting. This is starting in as little as 12,000 miles, 1/3 of which are on track.
The plate that was just removed had about 25 degrees deflection from spring to spring clockwise to counter clockwise. There is another 15 degrees before the spring starts to feel solid in the drive direction. With six teeth in the internal plates, mechanical damage can occur at 60 Degrees. There isn't excess face deflection, and there isn't run out.
