          loss of harmonic damping could be FTL...

              Actually, crank is balanced individually, so if this pulley is balanced, then it's not a bad idea at all.

              But, I doubt you'll see any torque gain. Try it, should be an easy install.

                  And I just saw the rest of that pulley, and I change my mind.

                  Don't buy it. It undermines BMW engineering. Take your dampener to a machine shop, and let them cut out extra weight out, and rebalance it.

                  I don't see how this one is balanced at all.
