any noticable boost in performance....
like 2 HP faster, maybe... it helps along the lines when you get goin with mods, makes for easier air flow
dont expect too much, it makes things a bit smoother, but not any power gains

They both will help in different ways. The hoses will make the spool a bit faster, and the pulley will help the low and mid-range power a bit. I 'felt' both mods when I did mine. I like the pulley because it helps when rev-matching and in heel and toe...which I do all the time.

i dont have a pully installed, but i can say that the hoses will make a small difference. if anything... it will make taking your inter cooler off and on alot easier.
