The RK Autowerks E39 M5 supercharger system was developed for the enthusiast looking for more power from his or her M5. Unlike many other kits where you lose drivability or reliability, our kit has endured the test of time and proven to excel in both areas. This is a result of countless hours of development, testing, and fine tuning. Each kit comes with a tune for your specific car, no off the shelf generic tune, ensuring you obtain every last horsepower! Fit and finish is equal to BMW OEM and 100% reversible in the situation where you may want to sell your vehicle. With the combination of all of this, the supercharger system produces a reliable 550 horsepower and 640Nm of Torque with surpassed smoothness and reliability of a stock car.
The system contains a Vortech V3si head unit at the heart of the system. This unit is self contained and does not require any external lubrication. Coupled with the 8rib billet crank pulley and spring loaded tensioner system, you are sure to not have any belts slipping under hard driving. We’ve also gone a step above the competition by producing aerospace grade carbon fiber pieces for the intake and the discharge, making the kit visually pleasing and being functional at the same time by avoiding heat soak you would get with aluminum pieces. Everything necessary for installation is supplied down to the last bolt.
With the addition of the new supercharger, recalibration of the ECU was developed as well. Reprogrammed throttle, fuel, ignition, Vanos, and EGR maps were developed to ensure you get the utmost reliability and performance from your M5. Factory failsafes were not compromised neither were OBD emission features. Allowing you to retain all of these features.
The system maintains all OBD-II functions, and it is backed by a comprehensive 2 year, unlimited mileage warranty. The system installs in 8-10 hours using normal hand tools and no irreversible modifications to the car is necessary.
