You want to make sure you get a quality pulley set. Not a piggyback style or no damper as Hoss's article states.
Honestly, for the little bit of power that is gained, it's not worth it. The dealer will void anything related of course. Your alternator, power steering and A/C will all suffer because those pulleys will rotate slower than stock. That's where you are getting the power from. Your only robbing Peter to pay Paul. Just not worth it. IMO Besides. 345hp isn't enough? Supercharge it then without going internally.

yep, do the e-fan first, if you dont have it already. that ones a little safer. i agree with all above, i wouldnt want to slow down my ac compressor, alternator, etc. The e-fan, i dont really see any downside to as long as you test it and know it can cool down enough. but theres plenty of info on here to do that without a problem.

Thats what i was thinking but I wasnt sure just how much power it would rob from my accesories, if it was even noticable. Im not dropping 3-4 grand on a supercharger plus install either, as much as I would love to. Havnt done the e-fan yet but plan on it in the future. This just seemed like a relatively cheap way to get some extra hp easily.

try it out first!
I have an underdrive pulley on my v6. Matter of fact, this is my second truck I have put an underdrive pulley on. I have never had problems with mine. The power gains are worth the money. However, do get a quality pulley. My alternator and a/c have never suffered. I also have the e-fan. Great combo! If I ever get a v8, one of the first mods will be the new pulley, no worries here.
