they all end up the same people. realize some people's parts 4 a rip 4 price and ur payin 4 a name. when u get down 2 it, any udp is a cant miss. just make sure u get it from a good dealer (sponsor preferable) and thats all u need 2 worry bout. yeah the h2o pulley is a nice idea, but its not necessary...and besides i know it'll unnerve a few of u slowin the water/coolant psi down.

the afx that tony d at www.newedgeperformance.com is said to be one of the best as far as actual hp increases. it's one of the smallest pullies out there. i'm going to go with the FC 3 piece, but that's just because i'm getting a great deal from a friend on his used set. otherwise i'd go with the afx.
<font size="2" face="Verdana, Arial">The Water pump pulley is larger to compensate for belt length. With the larger pulley the factory drive belt still fits. So you don't need a new belt and don't have to worry about remembering belt part numbers when it comes time to replace it.Originally posted by demonfire:

<font size="2" face="Verdana, Arial">If under drive is really what your after then go to tony D and get the AFX, it's the smallest of the bunch. On the three piece sets you'll get a larger water pump pulley to compensate for the smaller crank pulley, and this too will under drive the water pump even more than just the crank pulley. And I don't know if I would want to slow down the water pump too much, especially if you live in an area with high ambient temps already. The alternator pulley in these kits are the same diameter as stock, and the difference in weight is negligable so not much gain (if any) there. I had the AFX on my wifes car for a while and really didn't think it did much good untill I replaced it with the stock pulley, I could reall feel the difference then.Originally posted by 02InfraZX:
Which one??? none of the sites really give any specs on HP increases all seem to be very general. Anyone have an STR?? If the pullies are all about the same may as well get the cheapest one avaiable???
