Well I have bought an Unorthodox Underdrive pulley and am very hesitant to install it. I have seen a few sides to as this is a good or bad thing:

Why it works: Our engines are internally balanced, so there is no real need for a mass dampener, this is more of a redundancy and may cause a slight vibration over the lieftime of the enginer, but will have no effect on the engine that it can't handle, and it shouldn't ever even get close to hurting anything.

Why it doesn't work: We need mass dampening, maybe even a dual mass dampener as Ford is now doing to ensure engine bearing longevity, and anything without any mass dampening is just engine suicide.

Now I'm guessing the truth lies somewhere in the middle, but I am trying to see which side it is favoring here. Obviously we all want our cars to last forever and not be hurting it for a 4-5 HP gain. However, if this is nothing that will hurt the engine, it should be worth doing.

Lastly, is the SHO Shop pulley set worth getting instead, they apparently leave the factory dampeners on?

You are not going to find any "real" answer here. You can search and find that some like some don't like.... I personally do not have one but my friend does on his Ford Probe for many miles and nothing has happened yet as of 105,000 miles. Yes the SHO one has the factory dampen on it.

Personally I would use a DMD on the crank and get underdrive pulleys for your power steering pump and alternator.

Yes I agree 100%! Extend the life of your alternator and p/s pump while making more power! Sounds like a good deal to me!
