I was wondering has anyone just changed out their alternator pulley to the smaller March Performance pulley ? If so do yo have a belt number and brand of belt you used ?

I am going back to my factory crankshaft pulley but not changing the alternator pulley. I previously installed the three piece power amp pulley set up from March. The water pump pulley is same size as the factory pulley.

Any information on serpetine belt will help.

Leave the march crank pulley and use a small alt pulley.. less charging problems
Im not sure on your belt size the stock belt may work if its streached

 

You may be right I talked to another person today that said say thing. Not much difference in the smaller pulley than the March pulley and the factory size belt will probably work.

Thanks......
