The Edelbrock Universal Supercharger System #15885 is intended for Coyote engine swap applications using a Gen 1, Gen 2 or Gen 3 Coyote 5.0L engine. Its compact design fits under the stock hood on most applications and complements the clean look of any engine compartment. The core of this system is the Eaton Gen VI 2650 TVS rotating assembly coupled with Edelbrock's patented Dual Pass 3-Core intercooler making this the perfect choice for mild to wild power goals. Our unique, modular inlet configuration results in a shorter, less restrictive intake path for improved airflow without the need for a power robbing jack-shaft. This system includes two throttle body adapters, one with the stock Coyote bolt pattern and the other with the wider GT350 bolt pattern. Edelbrock 103mm throttle bodies (sold separately) use the GT350 bolt pattern. Two versions of the 103mm throttle body are available, part #38988 analog (for 2015-17 Gen 2 PCM) and part #38989 digital (for 2018+ Gen 3 PCM). NOTE: Edelbrock 103mm throttle bodies are NOT compatible with 2011-14 Gen 1 PCMs. Gen 1 applications may use the stock or Ford Racing 90mm throttle body part #M-9926-M5090 (not included). This kit includes the standard 6-rib belt drive system with 3.25? pulley for about 10-11psi. For high horsepower applications, an optional 8-Rib belt drive system part #15879 is available separately. Note: This system DOES NOT include fuel injectors, fuel pump, spark plugs, intake piping and calibration. PCM calibration is not available through Edelbrock for this system. Custom tuning is required.
