anyone got a ******?

liquid filling is for vibration more then it is for movement

Vibration and movement are the same things -builders of Kinetic Energy.

Energy (kinetic or potential) can neither be destroyed nor created, it can ONLY be converted. It can be converted into potential energy and stored (IE used to do work) or it can be converted to heat and then dissipated.

Solid motor mounts allow the energy to be converted into work...that work is to shake the body of the car, over and over again.

Liquid filled motor mounts (or our dampers), allow that energy to be converted into work, also. But that work is to force a viscous fluid through a small hole.

Only one of those things is quiet.

The engine mounts/motor mounts, whatever you want to call them - their primary function is to hold the engine and transaxle in the right place in the engine compartment. Obviously, this function could be accomplished with reinforced concrete or solid blocks of metal. Their secondary function is to elastically decouple the engine from the subframe and body. As 93rev2sev said, they accomplish this by converting movement and vibration into heat that occurs when the rubber is stretched, compressed, or put in shear.

The function of the OEM engine dampers is to limit the rate of engine movement, and to provide damping to prevent the rubber mounted engine from getting into any sort of oscillatory behavior. For the ME's in the room, this is a classic spring-mass-damper system, just like automotive suspension.

Think about what happens with an automotive suspension that has a bad shock or strut, IOW, it's missing the damping component - it can oscillate or bounce with very little energy input. This is an under damped spring-mass system. You don't want the engine bouncing around, so you install dampers.

Those actually look interesting. Could probably find good uses for those. Thanks for the link.

Ah nevermind. ****** kits for Focus and Mustang run between $400-500. Too much.

You could always take you ****** and help stangeater get his rotor off... http://www.shoforum.com/showthread.php?t=96402

I'm running TYSHO's solid ATX motor mounts, and a Pep Boys solid trans mount. Riding in a cushy car feels weird now.

all vibration is movement but not all movement is vibration, and the engine torqing around on the mounts due to horsepower is not the same as the engine moving on the mounts due to internal vibrations (which will happen weather your @ idle or at WOT in 4th gear)

the fact still stands, lots or cars will benefit from having a ******

-even I benefit from having a ******! so does she!

I do....

I've been considering this, since I don't care at all about NVH problems....

thoughts?

Oh.

 

[93rev2sev]

all vibration is movement but not all movement is vibration,

They both result in kinetic energy, that's the point. Either the kinetic energy is damped before the resultant shockwaves get to the unibody, or the unibody damps them...with the help of your ass and any other mass that it van vibrate.

and the engine torqing around on the mounts due to horsepower is not the same as the engine moving on the mounts due to internal vibrations (which will happen weather your @ idle or at WOT in 4th gear)

Exactly what do you mean by internal vibrations? A vibration is a phenomenon. Any certain mass will vibrate at a select few frequencies. At all other frequencies, that mass will remain calm. So they do NOT happen at all engine RPMs. If you are refering to the shockwave of the combustion process, that's at a frequency that humans don't hear...so we don't damp them...I think...

Pep Boys has a solid trans mount?

you'd be better off making some custom mounts that don't allow movement.......
