TuneRS Motorsports 4 inch lightweight under drive crankshaft pulley kit. Includes pulley, drive belt and new bolt. Pulley is made from 6061 aluminum and is anodized gold.
Improve horsepower and torque while reducing parasitic drag from the alternator, power steering pump and water pump. This pulley is also Spec Boxster legal. The Boxster/Cayman platform has a tendency to overwork and overheat the Power Steering pump to the point that some of the lines have been known to melt! Cars that are auto-crossed or tracked suffer the most from this malady. One of the simplest and most effective solutions is to install a smaller crankshaft pulley known as an under drive pulley, because it under-drives the secondary systems (A/C, Alternator and Power Steering). There are no negative issues with cooling, charging or steering, but there's an upside: the engine will get back about 5-7 HP!
