Just a thought.
When installing my un-dampened pulley (same one Jake Raby uses), there was not much working room between the fire wall and the engine. I had a hard time getting my socket and wrench in the tight squeeze to loosen and tighten the bolt. I do not know what the dampened pulley looks like compaired to the un-dampened pulley. If the dampened pulley is in any way thicker, you may have more difficulty doing the install.
Boxstaboy, I did notice a power gain. Can't say it was high, but it is there.
PS: If this kills my 2.7 engine, then I get to upgrade!
