Will I see any noticable gain at all from these? Are they a good investment or no?

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.

Im thinking my pump was already weak and since the alternator is slowed down, it reduced its output, giving less power to the pump.

Depends on what you use to measure your gains. If it's the track with lights and timers. You will notice a difference.

it's a good bang for the buck..what else will give you about 1hp per 5bux? I'd just use the crank pulley
