Do you guys think that this is really worth it. I will be pulling my motor so I might as well put one on since I have it out, but if you don't think I will need it, I will also have a fidanza and spec 2 clutch, let me know what you think
Still workin on her!!!!!!!

I bought one and noticed absolutely no difference.
I still kept my old one. I've also never had any issues with my rod bearings or oiling.
I ran the old one the whole time my 3L engine was in the car and a few months with the turbo. NO ISSUES from 1999 to summer of 03 when I changed it. The old one was starting to get a tiny groove from the lip seal but still wasn't leaking at all.
Is it better? I have to say that it does have the potential to be better because it can damp out more resonances than the stock one, but I don't think there is any proof.
I wouldn't buy it if there is nothing wrong with the old one or if you are only buying it because you are scared of the bearings going out.
I'm about 99% convinced the bearings go out because of oil starvation and not crank whip.

I felt a difference at high rpms. The engine feels smoother above 3500. I find myself staying in 4th gear sometimes when I should be in 5th because of the decreased vibrations. There could be other factors at play too. Maybe my engine mounts are worn, so I felt more vibrations with stock crank pulley. I don't know. But I did feel a difference. If you decide to get one, get if from Bill Jenkins at Signature Lincoln/Ford in Las Vegas. He sells them for about $50 if I remember correctly. Cheapest I have seen anywhere.

Ditto. I catch myself "cruising" in 4th at 60 to 65 mph (and other times I do it on purpose, waiting for a passing opportunity...) I never could do that with the stock pulley.
Any hp change (+ or -) is not enough to notice.
I think it's a good combo with the flywheel and clutch mods, esp.
But I'm no Warmonger, either. Just that the racing and engine building experts that I've read say that the flywheel/clutch is a good place to shave weight, but that the harmonic damper isn't. Some cases where adding weight/damping to the HD allows for increased hp. (I'm not saying the DMD will add power, though.)

I'll even add the other 1% to that statement!
The DMD is for NVH only. (which it quells fairly noticeably)
Also it should not gain or lose any power compared to the stock damper.

I put one on my car (ATX) and noticed nothing, but I think the ATXs have added mass that dampens vibrations more VS the MTX cars anyway. I have also read in one discussion about this topic that racing teams usually install something akin to a DMD to preserve their engines. If true this post & the one above speak volumes. The Jag X-types come with DMDs as well, I'm told.
Must be that jumbly-wumbly thing happening again.

They do it to get power. Reduction in parisitic loss to vibration, plus more stable cam profiles. And these guys are religious about weight.
