Re: UNderdrive pulley for 5.7 L hemi
Definitely noticeable power. My jeep seems to accelerate a little faster. Don't know if its worth the extra money though, unless you install it yourself and are wanting to do anything and everything to make your jeep run a little faster like me. I have no issues regarding charge to the battery, and have no negative impact on my AC(knock on wood). Id say do it, if your bored one day and have the extra money to blow. Other then that, its a very nice piece. You should check out my other thread where I actually ran 0-100 with the 20%UD pulley installed.
