The ProCharger P-1X and D-1X head units feature the robust, self-contained gearcase that is standard on most ProCharger models, but with a new aerodynamic compressor design that creates cooler charge air temperatures and more horsepower at the same boost level than our industry-standard P-1SC-1 and D-1SC. This higher efficiency design was engineered to be a bolt-in replacement for P-1SC-1 and D-1SC equipped systems and has even greater max-power potential.

These new designs are built on the same proven technology that propels the P-1SC-1 and D-1SC models to near 4-digit power numbers and slightly beyond, and feature the same step-up ratio. The compressor side of the supercharger (the volute and impeller) was redesigned with greater efficiency and less parasitic engine load in mind. This means less heat and less power needed to turn spin the impeller–and that adds up to more horsepower.

Both the P-1X and D-1X superchargers fit into the same brackets as P-1SC-1 systems and will be an optional upgrade for those who want increased performance on otherwise stock, modern V8 engines–to the tune of 10-15 more flywheel horsepower at the same pulley size (with stock motors running standard boost levels)!

… impressed not only by its performance on the chassis dyno, but the feel of the blower on the street, where it exhibits better performance in the midrange with no downside in driveability. While it feels good in that everyday rpm range, it is at the top of the tach where the P-1X really flexes its muscle.”
–Steve Turner, FordNXT Magazine


  • More power per psi, more maximum HP, and cooler charge air temperatures
  • 10-15 flywheel HP gain with P-1X on otherwise stock, modern V8 automotive engines
    at the same boost level and pulley size (vs P-1SC-1)
  • Even larger gains possible at the same boost level with built and modified motors
  • P-1X™ is 875+ HP capable and is a direct bolt-in upgrade for the P-1SC-1
  • D-1X™ is 1000+ HP capable and is a direct bolt-in upgrade for the D-1SC
  • Designed for today’s high flowing modern V8 engines producing 300+ naturally aspirated HP
  • Available now as optional upgrade with ProCharger Systems and Tuner Kits
  • Highly durable, High HP designs with a compact new state-of-the-art 9.0″ housing/volute
  • Higher efficiency produces cooler charger air temperatures and reduces parasitic engine load
  • Uses same proven gearcase as P-1SC-1 and D-1SC–also available with standard or reduced noise level
  • P-1X/D-1X volutes are slightly larger than P-1SC-1/D-1SC volutes
