This pulley is biggie sized to spin your alternator slower to reduce unneeded power losses. Like any other Sunbelt product, this pulley has been dyno tested and shows real power gains. Your electrical system will charge starting at 2500RPM, which means this is perfect for track use only - street cars will not maintain a charge.
Included spacers allow use with Valeo or Bosch alternators. Required rerouting of accessory belt. Belt not included due to various lengths required, but can be sourced at your local autoparts store.
