VF-Engineering chose to supercharge the BMW Z4 to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger. Maintaining the the original BMW quality, smoothness and reliability were the key factors in the VF design. This is where the VF Hex Flash software comes into full effect. VF has harnessed reliability of Vortech superchargers and quality of VF custom software with over 19 years of supercharging experience and worldwide OEM supply sources to create the ultimate supercharger system for the ultimate driver�s car.
  • All kits are setup at approximately 6 psi and create as much, if not more, power than similar products running greater levels of boost and aftercooling. UPDATED feature> the recent addition of the Vortech Si-Trim impeller has allowed our engineers to slow down the supercharger and still create 6 psi. The result: cooler intake temps than ever before! VF-Engineering supercharger kits are turn-key ready to install and no additional work or components are needed. The hardware and software is fully reversible and designed for a simple install and allowing ease of access for engine maintenance. The linear power delivery is well suited for both automatic and manual transmissions as it remains within conservative tolerances. VF engineers spent over 12 months software testing the BMW Siemens ECUs to perfect the smoothness and functionality of the supercharged vehicle. Software flash technology and latest BMW file versions have all been employed to provide the cleanest and the most reliable method of software installation with the use of a DIY programming cable and email-able software. Testing the software included extensive road and dyno test cycles, with acceleration and deceleration tests for drivability smoothness and ECU fuel management. All test cars were put through long term full throttle testing in conditions varying from wet cold climates to hot dry Arizona desert temperature for safe-optimal air fuel ratios and knock activity monitoring. Competently-written ECU software has allowed VF to fully explore the potential of the BMW engine, making over 40% more power in most applications.
