First question: Has anybody installed either the Standard Lightweight Crank Pulley
, or the Underdrive Performance Lightweight Crank Pulley
from Stillen? I’m wondering if there’s any noticeable performance improvement. For roughly $200 for the pulley and belt combo, neither one of these seem like a bad idea for a little extra horsepower.
My other question: What would be the pros & cons of the underdrive pulley vs. the OEM size pulley? ...I've never really done performance upgrades on any of my cars, other than installing K&N filters.
