ATI F-1A Procharger Supercharger Head Unit Only

Legendary ProCharger F-Series Superchargers
ProCharger F-Series superchargers were designed with one simple goal: blow the competition away. Since their introduction in 2000, ProCharger's ever-expanding lineup of F-Series superchargers have continued to be the standard by which others hope to be measured, both on the track and on the street. From the custom designed 7075 billet aluminum impeller to the CNC machined transmission case to the industry-exclusive, patented compound bearing design, each self-contained ProCharger F-Series supercharger has been designed to deliver maximum performance, pass after pass, year after year, championship after championship.

On the Street or Strip:
The highly versatile ProCharger F-1 supercharger lineup is compact enough for many of today's high-horsepower modified street engine applications, yet powerful enough for ultra-high street horsepower and hard-core racing applications.
