Alloy 176mm Crank Pulley

Increases boost pressure by driving the supercharger faster.

Harmonically balanced

High quality CNC machining.

Light weight to reduce parasitic power loss

We recommend using quality spark plugs 1 grade colder than standard.

Note: You will also require belt 5PK975 available in the service section and Undersize Idler Pulley.

Note: On some engines you will need to remove the timing pointers on the plastic cover, we suggest you re mark TDC for future ignition timing checks / adjustments.
