hey jay, i live like 10 mins from harleysville but anyways UDs you wont really notice any power but sure it is a good investment... they are cheap and will go good with other mods
i say put the money anywhere else you can. I installed ud pulleys on the crank and waterpump a month ago. Right after install the fuel pump was whining and then just yersterday, my car started cutting out and it was almost undrivable.
Alot of people say they don't like them but I have a set of ASP aluminums on my car and can tell you they make a noticable difference in power, I switched back to stock for a few days just to do some testing and could feel a loss on power by switching back to stock. I am running a ASP overdrive alternator pulley with this setup and have had no charging issues from it.
