To reiterate, this is not designed in any way to be a lightweight pulley. Anyone using a lightweight pulley undampened is looking for premature crank bearing failure.

Also remember that the ATI includes a replacement hub (and probably so does the quoted weight), while the Fluidampr and factory harmonic balancer both bolt onto the factory hub, so the ATI suffers by comparison because you're not comparing apples to apples, exactly.

[QUOTE=TTP Engineering] Each damper has advantages over the other and different fit characteristics. TTP is now selling Fluidampr units at $270 shipped if you mention this post.
TTP has become a Fluidampr convert.
JK, Scott Both ATI and Fluidampr are good products. I doubt you could go too far wrong with either one. You could go very wrong, however, without one or the other.

Regarding the HUB sprocket. The weight mentioned was WITHOUT the crank sprocket. Just the outside pulley weighs in at 8lbs + as measured by a digital scale.

Serious? 3.5 pounds heavier than the Fluidampr? Ouch! Thanks for the clarification, though.

There are many modifications necessary to get the ATi to fit and function and I have grown tired the install process, even though the press fit is superior. It is not worth my time.

no ****? 
Just about the most important aspect of an engine DAMPER is the fit to the crank. ATi units require a press fit so it is SUPER TIGHT and transfers all vibration to the damper. A fluid damper just bolts onto the same loose fit crank sprocket that basically falls off once the crank bolt is removed.
There is not a better DAMPER available than Ati, tis why Curt Brown used the ATi.
