The Edelbrock E-Force Supercharger system part # 15172 is designed for use with 2015-18 Dodge Charger and Challenger 6.4L cars. It delivers 572 horsepower and 531 ft/lb. of torque at the rear wheels. Featuring a unique design with minimal components makes it possible to fit an E-Force Supercharger under the stock hood. The core of this system is the Eaton Gen VI R2650 TVS Supercharger rotating assembly with a four lobe design with 170 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. We also designed our superchargers with an integrated bypass valve to help eliminate parasitic loss under light throttle, improving mileage potential. Our unique and efficient inlet configuration results in a shorter, less restrictive intake path for improved air flow, without the need for a jack-shaft. Keeping the air cool is a high capacity air to water intercooler and low temp heat exchanger. ALL 2015-Later Chrysler/Dodge Supercharger Systems WILL REQUIRE the ECM to be sent in for modification... HANDHELD PROGRAMMER NOT INCLUDED. This is an 8-10 day process/waiting period from the time they are received! Every step of the process is handled with next day shipping. Supercharger systems without tuners are not eligible for supplemental warranty. Supercharger systems sold without tuners are only emissions legal when used with the correct Edelbrock program, which can be downloaded at www.edelbrock.com. For safety, the Edelbrock supplied program will retain the factory vehicle speed limiter setting.
