Armed with over two decades of supercharging experience, we have created the ultimate add-on for the E9x M3, making one of BMW™s most legendary models into a monster on the street and track.

The E9X M3 VT1-550 supercharger system produces 550hp and 380lb-ft of torque at 5.5psi of boost. A 130hp gain over stock.

Featuring the self-contained Vortech V3 supercharger unit in Si trim, the supercharger is capable of producing up to 775hp.

The VT1-550 comes with a specially developed cast aluminum intake manifold assembly ˜ribbed™ with optimized runners and velocity stacks. This ensures optimum airflow efficiency under all RPM ranges. The manifold was designed not only for optimum flow, but for minimal weight to not disrupt the iconic handling balance of the M3.

The supercharger system includes the ESS E-Flash OBD2 cable and specific ESS MSS60 engine software that is perfectly calibrated for the VT1-550 supercharged engine providing optimum ignition timing under all conditions, recalibrated electronic throttle for quicker throttle response, recalibrated VANOS control, and perfectly optimized fuel delivery. The E-Flash allows the end user to upload the supercharger ECU software from any PC running Windows XP or newer and includes a full diagnostic and code clearing capability. Any future ESS software updates can be received by email and loaded directly to the car. The stock ECU software will be saved and can easily be restored in the future.

The system maintains all OBD-II functions and it is backed by a comprehensive 2-year, unlimited mileage warranty program. The system takes 8-14 hours to install using normal hand tools and no irreversible modifications to the car are necessary.

All this comes with our legendary no-compromise approach to supercharging, with vigorous testing conducted to both the hardware and software. Through this, we achieve reliability and quality that is on-par with the OEM themselves: only the best components in the industry have a place in our kits. In addition, the look and feel is OEM, from the way the compressor sits in the engine bay to the gentle and predictable response in power, nothing is hacked together, it™s precision and persistence at its finest.
