Well, the pulleys are finally on.
And I really do feel a diff, specially in low-end torque which is what I was shooting for and the engine seems to sound "beastier" and also sicne am putting less pressure on the gas pedal, am aussuming my mpg will go up
So, yes I definetly suggest this mod to anyone who wants to do it and has some mechanical knowldge, it took a friend and I about 2.5 hours to do the all thing with tools and a lift.
