What are the advantages of using Light-weight underdrive crank pulley kit ?
• Lightweight Crank Pulleys reduce parasitic drag placed on the crankshaft by underdriving the accesories such as Alternator, Power Steering and Air Conditioning. Underdriving slows down the accessories to use less energy from the crankshaft but doesn’t slow them down to the point the accessory operation becomes effected. Under 8 seconds: Most of the power gains are produced from the lightened weight of the crank pulley.
