Why would an automatic car be protected from 'whip' more? The auto car CAN rev just as high as the manual car can. Like I said in the post,
"There are alot of variables there. I think that is one clue to why the DMD is there mainly for NVH. If it was there to save the motor from shaking it's self to pieces then why isn't it there on every duratech motor? Why take the chance if you are the manufacturer? You're playing russian roulette with every motor you place in a car without this damper."
I think that placing the DMD only on cars that are available with manual transmissions doesn't make sense to me. The ATX car can and will rev just as high as a manual car if the pedal is pushed to the floor. This is why I am of the opinion that the DMD is for dealing with NVH issues, not the cure all for internal vibration problems.
Part of my response is to this, that it is a NVH and not a failure problem. Part is to the claim that the right oil will prevent this failure without regarding the physical properties of motors (I read you put the DMD on, so you "know"). The response was not necessarily to educate you , but to make clear to those others without a lot of knowledge that crank whip exists, oil won't fix it, and there are remediations that can prevent it to a greater extent (i.e. DMD). I am not saying Amsoil isn't a premium, fine oil. I am not saying ---- Brand oil isnt good. That synthetic Oil isn't good. I am not saying oil starvation or loss of lubrication doesn't happen.
Since this forum is read by many people, with varying degrees of experience and knowledge, I tried to write my responce with as many clear facts so everyone understands. It was not intended to flame, just educate. It is difficult to know everyones background. Terry H., whether you have a gripe with him or not, has an extensive background. I could write to his level and lose some of those here with little or no mechanical background. So I try to keep it simple.
So, no flame intended, just making sure the "general public" doesn't lose sight of some facts in the heat of the discussion.
FWIW, I am a Mechanical Engineer, spent 9 years as a Diesel mechanic (Local 440 Machinist and Aerospace Workers), I do vibration analysis, drivetrain alignments as a Mech. Eng. I have rebuilt engines , trannies (mostly truck trannies, Spicer, Mack, Road Ranger), I weld, I've driven 18 wheelers (professionally, not just once around the block). I have a strange and diverse work history. I have a lot of education (Masters Degree) and a lot of experience. I am not a 15 year old who just received his license and a car from mommy. So, you can disagree with me, but it doesn't hurt to regard what I am saying. Not comparing myself to Terry H, but even if you don't like him, he brings a lot to the table too. Pays to regard his statements too.
Just my Humble Opinion , anyway.....:)
