Re: 2.0 underdrive pully ? (hybrid gti 2)
the only underdrive pully i found is for the2.0 with serprntine the work is worth it by going to one belt you gain some horse but considerable torque.remember for every belt you lose between 3/10 hp. so with one belt you gain 8/13 hp. you can feel also serpentine you can keep your a/c in tact with very minimal hp. loss
