Our highest horsepower; 50-state legal supercharger system is now available for owners of late-model Ford Mustangs with the 5.0L engine. The new Edelbrock Stage II Supercharger #15388 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 this 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; we have upgraded the fuel system components to include larger 50 lb/hr direct-port fuel injectors along with our Fuel Pump Voltage Booster. A dramatic increase in airflow over the Stage I kit comes from a new 103mm billet aluminum throttle body (23mm larger than Stage I) and high-flow air intake system with 113mm MAF housing. Our wider 8-Rib Drive Belt upgrade minimizes slippage to maintain consistent boost pressure under full throttle. Each supercharger comes finished with a durable black powder-coating that blends nicely into the Mustang engine compartment and includes a preformed hose kit; hardware and a full-color step-by-step instruction manual to streamline the installation process. This is a true bolt-on that installs cleanly with no modifications to the hood or body. The potent Edelbrock Stage II system for the new Mustang is backed by our industry-leading 3-Year/36;000-mile Powertrain Warranty and is 50-state emissions legal.
