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.
