Where do I find a pully for alt
I am thinking of replacing the pulley on my alternator. When my spal daul fans kick in at night at idle everything dims. Idle is at 900rpm, once engine speed hits 1300 things are ok. I have a 105 amp alternator that the dyne sheet shows amps at about 30 at 700 and 60 by 1500. Where do I find a smaller pulley to speed up the alternator.....

Your alternator is amp challenged. Get one that puts out more amps. There are underdrive kits to do what you are asking about, but you still are going to be short on amperage. March has underdrive, probably Zoops and Billet Specialties too. Summit and Jegs probably carry them. It is going to be more than just the alternator pulley, and you will still need a higher amp alternator.
