WHIPPLE GEN 6 3.0L STAGE 2 SUPERCHARGER SYSTEM FOR 2024–2026 FORD MUSTANG 5.0L S650 – 50-STATE LEGAL
UP TO 875 HP / 660 TQ • BILLET 112MM THROTTLE BODY • CARB EO APPROVED
The Whipple Stage 2 Supercharger System for the 2024–2026 Ford Mustang S650 (GT & Dark Horse) delivers the ultimate blend of street-legal horsepower and OEM-level drivability. Featuring Whipple’s Gen 6 3.0L twin-screw rotor pack, billet 112 mm throttle body, and 120 mm high-flow inlet, the Stage 2 setup unleashes up to 875 HP and 660 lb-ft while maintaining full 50-state emissions compliance.
Engineered for the S650 Platform: Purpose-built for both GT and Dark Horse variants, the inverted Gen 6 design provides factory-fit installation beneath the stock hood — no cutting or grinding required. Whipple’s plug-and-play wiring and OEM quick-connect fittings ensure a clean, serviceable build.
Maximized Airflow for Higher RPM Power: Dual performance air filters feed a massive Crusher™ Y-tube intake and 120 mm supercharger inlet, compatible with 92 mm, 112 mm, and 120 mm throttle bodies. The billet 112 mm throttle body and revised inlet geometry allow higher RPM shift points and unmatched top-end power.
Gen 6 Twin-Screw Technology: The latest 3×4 rotor profile and optimized port geometry increase efficiency and reduce discharge temps, resulting in more usable power per psi than previous designs. Whipple’s precision machining and rotor sealing yield OEM-grade quiet operation and longevity.
Advanced Dual Cooling System: The patented dual-core, dual-pass intercooler forces air through each core twice for exceptional thermal efficiency. Paired with Whipple’s largest heat exchanger and high-flow Bosch pump, the Stage 2 system keeps IATs consistent for repeatable track and street performance.
OEM-Level Calibration: The included Tomahawk V2 flash tool delivers Whipple’s CARB-certified calibration, providing factory-smooth driveability, refined throttle mapping, and retained OEM safety protocols — all while remaining 100% street-legal nationwide.
