    Yes, it's worth it ! With your 918's, you're able to turn higher rpm's, so it's good to slow every thing else down some & gain some HP. Your charging system will still work fine too.

    but worth noting..get a Ud pulley with a harmonic dampener ..just like stock..helps stop harmful harmonic frequencies bouncing through your block weakening it
