Underdrive Pulley
This is the underdrive pulley made by Nick Boers, a member of the Chrysler3liter group. The way the pulley works is it slows down the belts which drive your power steering, A/C, alternator, etc... and frees up horsepower by doing so. It doesn't create more horsepower, it puts it to the ground more efficiently. I have not had a problem with the alternator not charging enough so there is no worry. The pulley is smaller than the stock crank pulley and comes with a different belt. Installation is very easy and worthwhile. HP gains will range between 8-9hp and you will gain .25sec in the 1/4 mile.

His pulley is pretty good and for the price of $100 with the belt its well worth it. Some people say that this is one of the most noticeable mods for the 3.0L. If you are interested then check out his site Nick Boer's Pulley. Only bad thing is I almost waited 3 months for the pulley???
