I do have a question though, I noticed that your crank pulley is 10% underdrive and the alternator pulley is 10% overdrive. What happens with the stock belts for the crank and the alternator..?? Do I need to change the belts for new ones or would I keep my stock belts in both cases..??

Appreciate your comments.
