Hey everyone...I was looking at the March underdrive pulley set/ram air item in the summit racing catalogue...Now I was wondering how much underdrive pulleys hurt your power options in your car...cause I heard that they mess with your stereo, and stuff like that...and what does everyone think of that u.p./ram air thing. thanx
