ATI D-1SC Procharger Supercharger Head Unit Only

Legendary ProCharger D-Series Superchargers
ATI’s self-contained (SC) ProCharger models are the first and only gear-driven centrifugal superchargers to feature self-lubrication, and contain the industry’s most advanced technology. In addition to the patented oiling design, SC ProChargers also feature the highest step-up ratio, exclusive billet impellers, and the industry's only billet gearcases for superior rigidity, sealing and appearance. These proven self-contained ProChargers were designed specifically for internal lubrication and have become the industry standard.

ProCharger D-1 Supercharger:
The best-selling P-1SC shares many of the design elements which deliver the record-setting durability and performance of ProCharger competition superchargers, and is also quiet and street legal. With their rugged design, these ProChargers are the only superchargers durable enough to be backed with a 3 year warranty and powerful enough to harness the benefits of intercooling.

By combining advanced supercharger transmission design with the highest quality oil, SC ProChargers produce a larger net power gain because they run cooler and consume less power than comparable oil-fed designs. SC ProChargers also feature an internal step-up ratio of 4.44:1 for improved belt tracking and traction, and maximum low-rpm boost and power.

ProCharger is also the first and only manufacturer to offer the choice of standard or helical gearset for noise reduction on the P-1SC-1 and the D-1SC supercharger models.
