3-5 HP?

Are they easy to install?

Got an AEM one yesterday for a good deal.

Mine was easy to install after I got the damn bolt off. :blink:

The engine reved faster, more response but I dont think it added any top end power.

^^^Ditto. Found the exact same results; very rev happy, little or no power increase. You say pulley-as in one? You will need a new, shorter belt as well. And a friend with an impact gun, to get the pulley off.
