Default Underdrive Pulley? Worth it?

Is an underdrive pulley worth it? Does it really deliver NOTICEABLE gains of torque and hp?! I was looking at the price for one and a belt and just was wondering if the money it wanted, actually delivered in return...

Anyone?

*note* Here's a link to the one I was checking out... http://www.stangmods.com/ASP-Underdr...226-526400.htm

well i think they work but if you ask mostpeople on here theres no bolt on worth the money unless its gears or a power adder(sc/nitrous/turbo). every hp counts no matter how small.

The HP claim is pretty exaggerated... they claim 16HP... in real life dyno shows about 4 to 6 RWHP gain... which is no where near 16 HP... more like 8...

I went with the Alt pulley and it was noticable but not "huge" gains. I liked the set I got from Pauls High Performance cheap too.

Alright sounds about what I expected from it. I am just making a "small" list to save up for during the next new year :P

I used to run the PHP alt pulley as well. It helped a tad.
