Super Light Alternator Pulley Later Multigroove Belt
Billet Aluminium SuperLight Alternator Pulley - Weighs Less Than Half The Weight Of The Standard One!
Less Weight - Manufactured On The Latest Multi-Axis CNC Machine From The Highest Grade 6061-T6 Aluminium Billet, Making Them Immensely Lighter Than Their Factory Steel Counterparts.
This lower weight yields a large reduction in the rotating inertia of the belt train, allowing the engine to accelerate faster.
The effect is similar to fitting a lightened flywheel and is particularly noticeable in the lower RPM range.
This is because the power required to accelerate a heavy pulley accounts for a much greater proportion of the available power at low RPM.
