The Edelbrock E-Force Supercharger Stage 3 System part # 15174 includes all of the essential components that a racer would need to build a custom supercharged racing setup for their 6.4L Chrysler HEMI engine. They offer flexibility in pulley selection, cold air intake and more. These systems are for competition racing use only. Features a unique design with minimal components and fits 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. 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. NO HANDHELD PROGRAMMER INCLUDED – will require custom tuning.
