Is the undertaker down??
And if your post wasn't for me.....nevermind…..
I think he was referencing a quote from a Ford Engineer that stated an aftermarket damper was once linked to some gears failing, as it aggravated the harmonics issue. However, Ford also stated the ATI dampers are good, but they would not name the bad damper (my guess was MMR or Innovators West).
Torsional and lateral harmonics are nasty and complicated beasts. If you grossly over-simplified it, you could say it’s a spring-mass-damper system. That said, adding or subtracting mass or damping (assuming we aren’t going to play with the stiffness of the system) could make the problem better or worse. I would venture to say that very few folks in the country can accurately model a system like this and design a damper that will make things better. Everything else is just guess-n-check. I wouldn’t even assume the ‘18 mustang damper is a sure-fire upgrade because of the firing order difference, though I would give it a higher chance of success than aftermarket.
