Construction & Design:

The Vortech Supercharger Kit is engineered with precision and durability in mind. The V-3 Si supercharger features a state-of-the-art centrifugal compressor stage developed in an SAE J1723 compliant test cell, delivering an industry-leading 78% adiabatic efficiency. This means less heat generation, improved reliability, and more net power output compared to traditional superchargers.

Its internal lubrication reservoir eliminates the need for complex oil lines, simplifying maintenance and reducing potential failure points. The dual-pass air-to-water charge cooler system efficiently reduces intake air temperatures, ensuring consistent performance and protecting engine components under boost. High-quality billet aluminum brackets and premium silicone ducting ensure a secure, long-lasting installation with a clean, factory-like appearance.

Performance & Sound

This supercharger kit boosts the stock 5.7L Hemi engine to approximately 432 horsepower and 471 lb-ft of torque, delivering a noticeable increase in acceleration and throttle response. The centrifugal design provides a smooth, progressive power curve that builds with engine RPM, offering strong mid-to-high range performance without the lag commonly associated with other forced induction types.

Unlike roots-style superchargers, the Vortech V-3 Si produces less heat and mechanical noise, resulting in a refined yet aggressive supercharger whine that enhances the driving experience without overwhelming cabin comfort.

Installation & Fitment:

The Vortech Supercharger Kit is designed for a 100% bolt-on installation on 2005–2008 Chrysler 300C, Dodge Charger, and Dodge Magnum models equipped with the 5.7L Hemi engine. Installation time is typically rated between 12 to 14 hours and requires moderate mechanical skills. The kit includes all necessary hardware, belts, pulleys, and a reusable high-flow air filter to ensure a seamless fitment with no permanent modifications to the engine or vehicle.

Vortech recommends adjusting the factory spark plug gap to .032” or using a one-step colder plug to optimize ignition under boost conditions. For custom tuning or racing applications, tuner kits without fuel system upgrades or ECM reprogramming are also available.
