Nissan 200SX Crank Pulley, to suit SR20DET engine in Rear-Wheel Drive Configuration only.

Install a GFB light-weight under-drive pulley kit and get better throttle response and more power!


How do they do this?

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.

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.

Under-Driving:

Additional power increases also come from making the crank pulley smaller, thereby
slowing down the accessories and reducing the driven load (particularly at high RPM),
without affecting their operation.
