Description

Alloy Crank Pulley For Honda B series engines in cars 1992 and onwards.  This includes EG/EK/DC2 Chassis.

These GFB alloy crank pulleys weigh about half what the stock unit does increasing throttle response and power!.

How do they do this?
1. Less weight - GFB's pulleys are manufactured on the latest Multi-Axis CNC machines from the highest grade 6061-T6 aluminium billet, making them immensely lighter than their factory steel counterparts. How much lighter? It depends on the particular model, but on average the weight saving is around 2kg. The GFB 300ZX pulley on the other hand saves over 7kg!

This significantly 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 before the turbo spools up. This is because the power required to accelerate a heavy pulley accounts for a much greater proportion of the available power at low RPM.
