South Florida Pulley HQ

Magna Charger Keyed Supercharger Pulleys are available in Aluminum in 2.75", 2.85", 3.00", and 3.10" pulley sizes.

We now offer keyed pulleys for the 4.8 & 5.3 Liter Magna Charger Radix MP112 superchargers!


Below are the Boost increases over stock 3.30" pulley application:
- 3.10" pulley: expect 2 lbs. more boost over stock pulley
- 3.00" pulley: expect 3 lbs. more boost over stock pulley.
- 2.85" pulley: expect 4 lbs. more boost over stock pulley.
- 2.75" pulley: expect 5 lbs. more boost over stock pulley

*** 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!

NOTICE: Installation and Removal of the Stock pulley over to our New Pulley will require a Power Steering Puller Tool for use on this pulley application. You DO NOT want to use any Aftermarket Puller Tool, as it will not work properly and will Ruin the stock pulley on removal. This Removal Technique is only for the Magnacharger Keyed Style Supercharger Pulleys applications ONLY!
