Magna Charger Keyed Supercharger Pulleys are available in 6061-T6 Aluminum in 2.60", 2.75", 2.85", and 3.00" pulley sizes.

We now offer keyed pulleys for the CTS-V Magna Charger Radix MP112 supercharger kits!


 Below are the Boost increases over stock 2.90" pulley application:
- 3.00" pulley: expect 1 lb. less boost over stock pulley.
- 2.85" pulley: expect 1 lb. more boost over stock pulley.
- 2.75" pulley: expect 2 lbs. more boost over stock pulley
- 2.60" pulley: expect 3 lbs. more boost over stock pulley

WARNING: The only way to install the 2.60" Pulley is to have the Snout Housing Machined down for it to fit properly. Some Snout Housing Castings are made differently in sizes and do vary, as to what the smallest pulley you can use without maching. The smallest size we recommend is 2.75", without any machining performed on the snout housing casting area.

*** Above Boost Increases are Fully Dependant Upon proper Tuning and Modifications, to prevent any and all Knock Retard associated with using Smaller Supercharger Pulleys or Pulley Units!
