How much HP do you gain with an underdrive pulley on a stock engine?
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.

Gas savings is a great way to justify a purchase to the wife!!
