Whipple X71: A Modern Twin-Screw Supercharger With Classic Blower Style
Whipple Superchargers has introduced its newest entry into the world of high-performance boost, unveiling the Whipple X71 Twin-Screw Supercharger: a modern, engineering-driven tribute to the iconic 6-71 blowers that defined early hot-rodding. The company describes the X71 as a fusion of retro attitude and advanced technology, built for enthusiasts who want the unmistakable look of an old-school roots blower without sacrificing the efficiency and power potential of contemporary forced-induction design.
At the center of the new supercharger is Whipple’s freshly developed 5.0-liter Gen 6 rotor pack, which the company calls its most efficient positive-displacement configuration to date. You may be familiar with their 3.0-liter and 4.0-liter displacements, but at 5.0 liters, the X71’s power capability is through the roof. The X-71 preserves the aggressive silhouette of the vintage 6-71 and 8-71 blowers while transforming them into a modern, highly capable performance system.
Gen 6 Power in a 5.0-Liter Twin-Screw Package
According to Whipple, the Gen 6 rotor pack was designed from the ground up to deliver maximum airflow, lower charge temperatures, and consistent reliability, which allows the X-71 to serve a wide range of builds. Whether the goal is a street-driven muscle car, a weekend burnout machine, or a full-throttle program aimed at dragstrip records, the X-71 is engineered to step far beyond traditional roots-style blowers in both output and refinement.
The X71 uses a high-flow port layout to improve efficiency and reduce parasitic losses, an integrated bypass system that smooths drivability and lowers heat during cruising, and a cog-style 8mm belt setup intended to maintain precise boost delivery under severe load. Whipple also designed the system with multiple drive-snout lengths to accommodate different engine configurations, giving builders flexibility during installation.
“This is the perfect blend of nostalgia and next-generation engineering, giving enthusiasts the aggressive look they love with the performance they demand.” – Dustin Whipple, President of Whipple Superchargers
Designed For Street And Strip
“The X71 is our tribute to the superchargers that shaped hot-rodding culture, but rebuilt the Whipple way—stronger, faster, cooler, and far more efficient,” said Dustin Whipple, President of Whipple Superchargers. “This is the perfect blend of nostalgia and next-generation engineering, giving enthusiasts the aggressive look they love with the performance they demand.”
With its combination of retro flair, technical sophistication, and the torque-rich characteristics of Whipple’s twin-screw architecture, the X-71 represents a new chapter in classic-style superchargers and signals the company’s continued push to modernize iconic performance hardware for today’s horsepower-hungry builders.

The Whipple X71 is a twin-screw supercharger built around a 5.0-liter Gen 6 rotor pack. It combines the visual profile of classic 6-71 and 8-71 roots blowers with modern forced-induction efficiency, lower charge temperatures, and an integrated bypass system.
A traditional 6-71 is a roots-style blower with a fixed drive ratio and no bypass. The X71 uses twin-screw positive-displacement technology, which builds boost more efficiently, runs cooler, and loses less power to parasitic drag than a conventional roots design.
The X71 uses a cog-style 8mm belt setup. The positive engagement of a cog belt keeps boost delivery consistent under heavy load and high rpm, where a standard V-belt can slip.
Whipple engineered the X71 to work across street-driven muscle cars, burnout builds, and dedicated drag strip applications. Multiple drive-snout length options give builders flexibility for different engine configurations.
The X71’s Gen 6 rotor pack displaces 5.0 liters, which is larger than Whipple’s more common 3.0-liter and 4.0-liter configurations. That extra displacement translates to significantly higher potential airflow and power output.
