What is this?

[BSTD3]

Hey guys:

Was under my Speed3 this am installing my Cobb rear sway and saw this block of metal with a bracket attached to the frame.

Anyone know what it is for? I don't see any connection to it, just the 2 bolts for the bracket that attach it to the frame.

TIA!

I found a similar block of metal bolted near the driver side motor mount, puzzling.

Is the Block Rubber..or metal....It might be a Vibration Damper of some sort.
Not un-common to find things like this.

[Young Roids]

The one I found was metal. And yes I just called it a harmonic dampener.

[GhostMercury]

i didnt have one of those..hmm

Yours must have falling off or something... How do you like that Desert Eagle shift knob btw?

It def was metal. I rapped my socket against it. Not sure if it was solid metal or hollow, but it was metal.

Must be a dampener.

very interesting indeed.

its a black box....for dealer to check if u been driving over aggressive

ummm yeah ok....

[Lil Freek]

Remove it... Dead Weight IMO...

[07SilverSpeed6]

Just guessing...Ballast weight for more downforce or lower CG?

That's the housing for the flux capacitor hyper-ventilation system.

That is actually 3 kilos of cocaine wrapped up and painted black because your Mazda dealership is using you as a drug mule.

[controlo]

haha. does anybody actually know what it is?

[xDJ DUBx]

ahaha, funny shit right here.

Maybe if your car blows up it will tell what went wrong, like a black box on a air plane (thumb)

tuned mass damper. I would leave it in place, and I'm the idiot who thinks the billet oil cap is too heavy

[Rotus]

I'm sure that previous posters nailed it when they identified it as a harmonic damper.

BTW, just for future reference, the word is DAMPER, not dampener. It's just a pet peeve of mine. Dampening somthing is to make it slightly wet. Damping something controls unwated oscillations.

Thank you for your time. ;)

haha. pet peeves ftw.

...(uhm) so what exactly would this damper be damping?

[Rotus]

haha. pet peeves ftw.

Road vibrations/noise coming into the cabin from that suspension piece.

I found one on my Audi TT stock exhaust, just a chunk of metal and rubber in the middle of the exhaust. When I replaced the cat back, I made sure to keep the damper.

This guy pretty much answered your question.

Right. Think about a rope that's fixed to a wall at one end and in your hand at the other end. If you shake your hand up and down at a certain "resonance" frequency you can get the rope into a "mode" where a wave will travel back and forth along the rope. If the rope represents your sub-frame, these waves or vibrations are undesired. Now imagine a weight being taped in the middle of the rope. It would no longer wave or oscillate quite the same way at that particular resonance frequency. Hence "tuned" mass damper because its weight (mass) and location are carefully tuned.

They're very common on exhausts for some reason, maybe because engine speed and exhaust velocity can excite many different resonance frequencies. When you installed your new exhaust, it's unlikely that the TMD would still be required since the new exhaust would have a totally different weight distribution and vibration characteristics than the old one :)

actually, that would be moar like 1/2 kilo of coke. Here is what 1k looks like. Note dime for scale (lol, dime).

It had been tried without by other TT owners and found to be helpful with the aftermarket exhaust. It wasn't detrimental to performance, so I transferred it.

Hyundai makes cocaine now?

I mean, I guess its cool that they're trying to go after a new market (ugh)

Well since they are in the luxo-barge market now, they have to horizontally integrate.

Horizontal integration ftw?
