The ESS E39 M5 G1 supercharger system delivers unparalleled acceleration and everyday driveability matched with the reliability customers have come to expect from ESS. Countless hours of development and testing have resulted in a supercharger system that produces 570 horsepower and 640NM of torque with the smoothnes and drivability of a stock car. Component quality matches or exceeds BMW OEM specification throughout the kit.

The system is based on the ultra light, high efficiency, internally lubricated G1 supercharger. The redesigned ESS MSS52 engine control software is perfectly calibrated for the supercharged engine providing optimum ignition timing under all conditions, recalibrated EGas for quicker throttle response, recalibrated VANOS control and perfectly optimized fuel delivery supplied by 8 larger Bosch injectors ensures that the engine is operating ideally under all conditions.

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.

The kit comes with the ESS E-Flash OBD2 cable which allows the end user to upload the supercharger ECU software directly to the car from any PC running Windows 7 or newer. The system also includes full diagnostic and code clearing capability. The stock ECU software will be saved and can easily be restored in the future.
