2024-2026 Ford Mustang S650 Whipple Stage 1 to Stage 2 Upgrade Kit

2024-2026 FORD MUSTANG S650
WHIPPLE STAGE 1 TO STAGE 2 UPGRADE KIT

For S650 Mustang owners already running a Whipple Stage 1 system, this upgrade kit provides a straightforward path to the stronger airflow and added performance of the Stage 2 package. Instead of replacing the full system, this package focuses on the key airflow and calibration changes needed to step up to the next level.

The 72-70151 upgrade package is designed to convert an existing Whipple Supercharged 2024-2026 Ford Mustang S650 Stage 1 combination into the Stage 2 configuration. The package includes a billet 112mm throttle body, 120mm Y inlet tube, billet 3.75" Whipple supercharger pulley, and revised calibration to support the additional airflow and performance potential.

With the proper supporting Stage 1 base system already in place, this upgrade can increase output from *810 horsepower and 640 lb-ft of torque to *875 horsepower and 650 lb-ft of torque under optimal conditions on 93-octane fuel. The revised calibration also includes increased RPM, airflow, and speed limits to fully support the Stage 2 configuration.

This is a practical upgrade for customers looking to move beyond the standard Stage 1 package while reusing their existing Tomahawk flash tool on the same VIN. It is a clean, bolt-on way to unlock the next step in Whipple S650 performance.
