For Mustang enthusiasts seeking to unleash the ultimate performance from their 2015-2017 models, the Roush Phase 2 Supercharger Upgrade Kit represents a significant leap forward from the Phase 1 system. Understanding the nuances between Fuel Pump Phase 1 Vs Phase 2 upgrades is crucial for achieving peak horsepower and torque while maintaining engine reliability. This article delves into the enhancements offered by the Phase 2 kit, focusing on how it elevates your Mustang’s performance to an exhilarating 727 horsepower.
The original Roush Phase 1 supercharger system already provided a substantial power increase. However, the Phase 2 upgrade builds upon this foundation, delivering an impressive 57 horsepower and 65 lb-ft of torque gain. This remarkable improvement culminates in a staggering 727 hp at 6,850rpm and 610 lb-ft of torque at 5,100rpm. This power surge is achieved through meticulous engineering and the integration of key components designed to work in perfect harmony.

A critical element in the Phase 2 upgrade is the preset plug-and-play digital fuel pump controller. This innovative component safely and reliably increases fuel pump output, ensuring your engine receives the necessary fuel to support the increased power demands. Unlike more invasive fuel system modifications, this controller offers a seamless installation without the need to open the fuel system, maintaining the integrity and safety of your vehicle. This addresses a key aspect of fuel pump phase 1 vs phase 2, as Phase 2 requires enhanced fuel delivery for its higher output.
To complement the increased boost levels, the Phase 2 kit includes cooler heat range Ford spark plugs. These spark plugs are essential for ensuring complete combustion and preventing detonation under the higher pressure conditions within the engine. By utilizing colder heat range plugs, Roush ensures optimal engine performance and longevity, even under the stress of increased power output.
Further contributing to the power boost is the smaller diameter 80 mm supercharger pulley. This pulley, easily installed in minutes without requiring belt replacement, increases boost pressure, directly translating to more power. The reduced size of the pulley speeds up the supercharger, forcing more air into the engine and maximizing performance gains.

The Roush/Ford Racing Phase 2 calibration file, delivered via the exclusive Roush Diagnostic Tool (RDT), is the final piece of the puzzle. This precisely engineered calibration file optimizes the engine control unit (ECU) to work in perfect sync with all the upgraded components. Installed quickly through your authorized dealer, the RDT reflash voucher ensures your Mustang’s computer is programmed for peak Phase 2 performance.

It’s important to note the emissions legality of the Roush Phase 2 Supercharger Upgrade Kit. It is 50-State emissions-legal for 2015-2016 Mustangs (CARB E.O. #D-418-29) and approved for sale or installation on 2017 models in California (CARB E.O. #D-418-34). Furthermore, the kit is backed by a 3-year/36,000-mile Roush Parts only limited warranty, providing added peace of mind. However, installing this kit on a 2015-2017 Roush Stage 3 Mustang may void the vehicle’s powertrain warranty.
In conclusion, the Roush Phase 2 Supercharger Upgrade Kit offers a significant performance enhancement over Phase 1, delivering a thrilling 727 horsepower while maintaining the drivability and reliability expected from Roush Performance. By focusing on key upgrades like the fuel pump controller, spark plugs, pulley, and ECU calibration, Phase 2 transforms your Mustang into a true powerhouse. For Mustang owners serious about maximizing their vehicle’s potential, understanding the fuel pump phase 1 vs phase 2 difference and opting for the Phase 2 upgrade is a clear path to unparalleled performance.
