like the title says, a brand new never opened box of GFB pullies.


Average Power Gains that can be expected are up to 7kw for normally aspirated engines and up to 9kw for forced air systems. Coupled with the excellent anodised finish and fit, you'll have a pulley kit that will give you the extra edge you need!

How do they do this? 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. 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 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. Additional power increases also come from a slight change in the ratios to reduce the driven load of the power-robbing peripheral components (particularly at high RPM), without affecting their performance.
