I did an A- B comparison (with, without) on one of my cars with the weight on the trans, didn't notice any significant difference. John The dream is dead, long live the dream.......😥

Well its a street/strip car and I have to drive on the highway to get to NewEngland Dragway,E-Town,or where ever else the car takes me. I have no problem removing it if all it will do is decrease smoothness/quietness. I don't want to remove it if it will cause broken tailhousings or other bad things. ~Mike~

My engine shakes worse than a dog in heat at certain RPM's (engine issues) and nothing has spit out in over 7 yrs of driving it this way. (engine otherwise runs fine, just don't have the $$$ to rebuild it and get it properly balanced ). John The dream is dead, long live the dream.......😥

There was even dampers inside the steering wheel on some cars, as well as under the dash. The damper on the trans is a Power plant bending damper (PPD). The car will as a rule get a little noiser as not all cars needed them. Some cars just didn't have the problem, but most did. The heavy damper on the floor pan is called a Boom Damper. Of course it stops the floor pan from booming. Take them off if the noise doesn't bother you.

From your factory experiences what areas needed the most attention for noise reduction ??? I like to make my mopars handle well at the usually adds to ride stiffness and adds to noise, vibration, and harshness (NVH). There are a lot of threads here about adding sound deadner and even frame connectors to reduce NVH I knew a guy who lived in central Iowa that work for Chrysler in the NVH department.

How excatly did the "power plant bending" whatever gets its name? Was anything really "bending"? Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

The thing has got to weight twenty pounds with the bracket. The 8 1/4 has lived forever without the damper in older applications. I guess the people today never heard of good vibrations. They still complain about vibrations in the jeep. best of 11.39 at 117 mph 1.60 60’. 68 340 S Barracuda Fastback F.A.S.T [IMG]http://i67.tinypic.com/2mnnnnt.jpg[/IMG]
