FS 944 alternator underdrive pulley $40
Have an aluminum (blue anodized) underdrive pulley of Broadfoot heritage availble...I bought the set for the crank pulley, don't need the alt pulley for my projects.
Underdrive pulley is larger than stock alternator pulley, so it slows down the alternator RPM with the idea being this frees up some HP (lower friction).
Maybe useful for a track car or somebody who spends a lot of time at higher RPM, or someone with low electrical loads in their car.
Used, looking for $40 + $7 shipping USPS flat rate, will take offers.
