The Edelbrock Supercharger System part #15175 for 2015-18 Dodge RAM trucks equipped with a 5.7 HEMI V8 engine delivers 439 RWHP and 444 RWTQ. Featuring a unique design with minimal components makes it possible to fit an Edelbrock supercharger under the stock hood. The core of each system is the Eaton Gen VI 2300 TVS rotating assembly with a four-lobe design with 160 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 airflow 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.
