Raine is correct plus the ALT pulley provided ZERO gains, it's basically like the water pulley, in a two piece it's sized so you can still use your stock belt. FYI, a one piece will provide the same gains as a two or three piece. It's more the convienence of using the stock belt that people opt for a two piece. All the gains come from the crank pulley.
