Re: Pulley Kits, Worth it or Not
Worth it performance wise, no. The general underdrive pulleys do nothing but spin the accessory pulleys slower, taking less power from the crank. The pulleys are also lighter weight than the stock ones. Overall the power gained through this is negligable.
Another thing to keep in mind is the stock crank pulley is a harmonic balancer. It keeps down torsional vibration made by the engine throughout the RPM range. Most pulley kits do not offer a dampened crank pulley. Though no one will ever or has ever reported an engine being harmed from using a non-dampened crank pulley, do you want to be the first to do so?
