Description
Unlock maximum horsepower with the Edelbrock Stage II Supercharger #15388, the highest-output 50-state legal supercharger system for 2018-2021 Ford Mustang 5.0L Coyote engines. Designed to take full advantage of the Gen 3 DI/PI Coyote engine, this system delivers exceptional power, reliability, and smooth acceleration throughout the entire RPM range.
At the core of this system is the high-efficiency Eaton R2650 TVS rotor assembly, featuring 170-degree high-twist lobes, larger bearings, and reinforced timing gears for unmatched durability and performance. The integrated Dual-Pass Three-Core (DP3C) air-to-water intercooler reduces inlet air temperatures, maximizing boost efficiency and power output.
This Stage II upgrade enhances the fuel system with 50 lb/hr direct-port fuel injectors and a Fuel Pump Voltage Booster, ensuring proper fueling at high power levels. Airflow is dramatically increased thanks to the 103mm billet aluminum throttle body (23mm larger than Stage I) and a high-flow air intake system with a 113mm MAF housing. To maintain consistent boost pressure under full throttle, an 8-rib drive belt upgrade minimizes belt slippage.
Finished in a durable black powder coating, this bolt-on system installs cleanly with no modifications to the hood or body. Every kit includes a preformed hose kit, mounting hardware, and a full-color step-by-step installation manual. Backed by Edelbrock’s industry-leading 3-Year/36,000-Mile Powertrain Warranty, this supercharger offers street-legal performance with unbeatable reliability.
