Euro Sport VW Mk4 VR6 12v Crank Underdrive Pulley KitSKU:
Euro Sport Crank Underdrive Pulley Kits
Tap into hidden horsepower with a new Euro Sport crank underdrive pulley (UDP)! CNC machined from 6061 aluminum, these crank pulley kits underdrive your accessories by 23% on 4 cylinder engines and 13% on VR6 engines. This, in turn, decreases engine drag, unleashing power that you never knew you had. And since the Euro Sport crank underdrive pulleys are lighter than the OEM crank pulleys, you'll benefit from the weight reduction of rotating mass; resulting in a more responsive engine. As an example, compare the Euro Sport Mk3 8v pulley at 11.6 ounces to the OEM Mk3 8v pulley at 3 lbs. and 4 ounces. Euro Sport crank underdrive pulleys come in a blue anodized finish.

Love how this make the VR6 rev so free, not as good as a lightweight flywheel but it's the next best thing.
