x2. There is a 3 pully set made by JET (I think) that adds a couple HP. Nice cheap mod for the 3.4. Some people have seen under charging from the alt with this set if they run too many electronics. I have not had such issues.Originally posted by Black 00 BirdComment

in the case of a crank pulley, i believe it is smaller, and therefore less energy is spent turning engine accessories, so more is sent to the rear wheelsComment

Re: underdrive crank pulley?
I have one, but I dont think its worth it. I only did it because I had to replace my belt. I didnt feel any difference and this a pulley will underdrive your water pump, alternator, etc (not good)... But if it were a weekend/track car I would recommend it...Comment
