Kraftwerks Supercharger Cogged Pulley (159-99-750C) 5019 This cat-back exhaust system incorporatesIf you want your ROTREX supercharger work more efficiently, then it is vital to provide it with ROTREX or KRAFTWERKS pulleys as they will improve your vehicle performance. The supercharger compresses the air into the combustor and the pulley enables its spinning, so the faster the supercharger spins the more air will be compressed. That's why having a proper pulley will provide a pressure boost and therefore will increase the supercharger efficiency.
