i just got the pulley on my car and it was soooo easy to do. i noticed a little difference in how the engine revs when its not in gear. other than that it didnt seem to do a whole lot. im sure with the balance shaft removal it will help alot.

i only have an intake and that pulley now so theres not much done to it to really notice a difference.

Yeah, it's gonna be hard to feel the difference from one pulley, but hey, a horse gained is a horse gained.
