When swapping the Predator supercharger on to your Coyote Mustang or F-150, one of the first things you need to address is the pulley size.

The factory pulley on the Predator is approximately 3.0" in diameter and entirely too much boost for an otherwise stock Coyote engine. By utilizing our Predator hub system, it opens up the ability to pulley up and/or down for your desired power goals.

We recommend the 3.4" pulley in 6-rib configuration to align with your Street FEAD system and be compatible with your factory A/C compressor and harmonic damper.

This is a fantastic baseline boost level for 93 octane and a great starting place for additional modifications to your vehicle in the future!
