Introducing the JHM Supercharger: Unleash the Potential of Your B8 RS5 4.2L
Discover the ultimate solution for enhancing the power of your B8 RS5 4.2L with the groundbreaking JHM Supercharger. This revolutionary upgrade offers unparalleled performance gains that transform your unassuming German coupe into an undeniable force to be reckoned with on the road and the track.
The JHM Stage 3-4 Supercharger Kit serves as the cornerstone for a range of power levels available for the RS5 4.2L. This kit lays the foundation for achieving your desired power output levels through the incorporation of dedicated supporting hardware modifications. Notably, the heart of this Supercharger Kit is the same Vortech V3 Si head unit that propelled our in-house 2007 B7-RS4 4.2L FSI to a remarkable 10.7-second quarter-mile time at a blistering 130 mph way back in 2013. Remarkably, this feat was accomplished with full vehicle weight, complete interior, exhaust system, and street tires.+
JHM Stage 4 B8 RS5 10.85 @127.91 mph on 93 Octane
JHM Stage 3+ B8 RS5 11.07 @125.08 mph on 91 Octane
Our JHM Stage 4 Supercharger Kit for the B8 RS5 will make an additional 130 to 160 wheel horsepower (WHP) and Stage 3+ will make an additional 110 to 130 wheel horsepower (WHP) over your car's current configuration. Your current modifications, the dynamometer (dyno) used, temperature, elevation, and octane of gas will all effect the exact amount of power gains.
Unrivaled Features and Specifications
At the heart of our Supercharger Kit lies the Vortech V3 Si Centrifugal Supercharger Head Unit, boasting the capability to deliver up to an astounding 775 horsepower. Through our meticulous development and testing process, we've expertly tuned the supercharger's output to ensure it remains within safe limits for the stock RS5 4.2L motor. With helical cut gears, the V3 Si blower operates nearly noiselessly at idle and low speeds, with its true power roar becoming evident at wide-open throttle. The high rpm power feels endless due to the 3.61:1 step up gear ratio in the V3 Si which increases boost as RPM increases.
Crafted in-house, the JHM Supercharger Kit includes precision-engineered Supercharger Mounting Brackets made from reinforced steel. These brackets undergo laser cutting and are elegantly powder-coated in black, ensuring a seamless installation that enhances both performance and aesthetics.
Uncompromising Reliability and Durability
To bolster the longevity and robustness of the RS5's belt and pulleys, we've upgraded the OEM components to a high-performance 6-rib system using our JHM 6-Rib Accessory Belt Conversion Kit (sold separately). This kit incorporates three specialized JHM Supercharger Kit pulleys, including a balanced Alternator Pulley, a precisely balanced Crank Pulley, and a Supercharger Pulley capable of delivering 7 to 8 pounds of boost (boost levels may vary based on factors such as exhaust system, modifications, and environmental conditions).
Acknowledging the limitations of the factory PCV system under boost conditions, we've innovated the JHM Billet PCV System for the RS5 (available as a separate purchase). This upgrade replaces the vulnerable factory components with a singular billet alternative that is fully serviceable, promoting reliability in the most demanding situations.
Design Excellence
In addressing the spatial constraints of the V8 RS5's engine bay, we've positioned the Vortech Supercharger Head Unit on the passenger side, beneath the headlight. This necessitated the creation of a series of proprietary components, including our JHM Supercharger Kit Silicone Inlet and Outlet Hoses. Notably, the Inlet Hose is fashioned from reinforced silicone to prevent vacuum-induced collapse. Incoming air passes through a serviceable conical air filter designed specifically for the JHM Supercharger Kit.
Our JHM RS5 Supercharger Kit proudly features an integrated Air-to-Air intercooler, ensuring optimal IAT management. Our kit averages an IAT increase of only 4c to 7c during a quarter mile pass. Seamlessly integrated behind the grille, this Front Mount Intercooler replaces the factory crash bar while retaining the original oil cooler mounting and tow hook functionality. Our deliberate choice of an air-to-air design ensures a clean installation and consistent performance, free from concerns of heat soak.
