Hey I'm trying to order an ATI Super Damper to help fix some vibrations I have. I want it underdriven and I don't really care if I have AC or not (currently the compressor froze and is removed anyway).

They have the following chart on thier website, but I'm not clear on the advantages/disadvantages of the different part numbers:

My big questions are:
What's the difference between steel/aluminum Shell other than weight?
What's the difference between steel/aluminum hub other than weight?
Which part number should I order?

My current mods are in my signature, but I would like to prevent from buying one when I build my motor which will be NA.

Thanks for any help, thier office is closed but I wanted to get it on order today!

the aluminum one is lighter and will help the motor rev quicker

Is there any sacrafice to relability or to its affect on dampening crank vibrations? I know that it has a lighter rotating mass which will spin faster, but why aren't all of them build that way then? There must be a logical reason for selling so many different variations.

each one has its application. different strokes for different folks

For a street car - Steel hub and 10% under drive aluminum shell.

You should go ahead and get the version with the A/C pulley in the event you want to put the A/C back on in the future.

The part number to look at: 917276

I'll be doing the steel/steel stock sized damper when it comes time (going from my Powerbond to that), and underdriving the alternator to keep its RPMs in check. For me personally, I'd rather have an all steel damper just due to its importance and where it is located.
