Changing the pulley ratio increases supercharger rpm and produces more boost.The direct increase in airflow is seen by the ECU where it will compensate fueling accordingly thus increasing power across the rpm with impressive mid-range. Being the later model ECU's these engines will also benefit from a remap to unleash the full potential with the new pulley allowing peak boost and power to be increased. Please contact us for details about our in-house fitting of these pulleys, as well as our remapping services. Some basic workshop tools are required to gain access to the supercharger pulley. Removal can be completed with mild heat and a suitable puller for the pulley. If using a conventional puller the radiator may need removing, specific pullers for this engine may only require loosening a.
