Edelbrock's highest-horsepower, 50-state legal supercharger system for late-model Ford Mustangs with the 5.0L engine. The Edelbrock Stage II Supercharger W/O Tuner (part #153880) for the 2018-2020 Mustang is a complete kit that takes full advantage of the improved Gen 3 DI/PI Coyote engine. At the heart of the system is the highly efficient R2650 TVS rotor assembly with an integrated high-capacity DP3C (dual-pass, three-core) air-to-water intercooler for lower inlet air temperatures and increased power potential. New 170-degree high-twist lobes, bigger bearings and beefier timing gears ensure unparalleled reliability with smooth acceleration throughout the powerband. To support the additional Stage II power increase, the fuel system is upgraded with larger 50 lb/hr direct-port fuel injectors and a Fuel Pump Voltage Booster. This kit is sold without a tuner.
