Centrifugal superchargers are one of the most popular power adders to bolt onto a street car or race car to crank up the horsepower levels. These superchargers have not only grown in popularity as their development and subsequent capabilities have increased, but they’ve also grown in size to make them a viable option for the quickest and fastest classes in drag racing. Today, we’re going to look at ProCharger’s lineup of F-4X superchargers and learn about what makes them such impressive pieces of boosted technology.
To set the stage for what we’re going to cover, let’s do a quick refresher course on how a centrifugal supercharger works. A supercharger case is fitted with gears that are used to turn the impeller and move air through the unit. The ratio of these gears dictates how fast the supercharger will spin. The ratio can be tuned to match the supercharger’s performance envelope to the engine’s.
ProCharger’s F-4X supercharger has set records in multiple classes on slicks and radials.
The F-4X Series Of Superchargers Explained
If you were going to create a roadmap of the upgrade path for ProCharger’s superchargers, the F-4X series would be the final stop. These units were developed to be the next evolution of ProCharger’s product line from the F-3 series, to quench the horsepower thirst of those trying to go as quick and fast as possible.
The F-4X series of superchargers were created using a clean slate and went through a rigorous testing process. ProCharger engineers collaborated with racers to optimize the final product so it could work in the high-horsepower classes of the drag racing world. This was done to ensure that the racer’s needs would be met.
Cliff Hall, engineering director at ProCharger, talks about the development process for the F-4X superchargers.
“Understanding what and how the F-4X came about is core to understanding the success of these three products in the F-4 lineup. The F-4X concept evolved from years of experience with past ProCharger models. The design began as a 3D model, went through simulation, and then prototyping. Engine builders, race teams, and ProCharger engineers were all involved in the lab testing, dyno testing, and track testing to fine-tune the design and launch this product.”
ProCharger’s engineers spent a large amount of time refining the design of the F-4X supercharger. The goal was to develop a blower that could take a beating and make big horsepower.
