Experience a dramatic enhancement in throttle response and mid-to-top-end power with the VF-Engineering Supercharger System for the BMW Z3. Utilizing the centrifugal Vortech supercharger, this system delivers significant performance gains while maintaining the original BMW quality, smoothness, and reliability. All kits are set up at 6 psi, producing as much, if not more, power than similar products running higher boost levels. Leveraging over 10 years of supercharging experience and worldwide OEM supply contacts, VF-Engineering combines the reliability of Vortech superchargers with custom software, resulting in a system that enhances the BMW Z3's performance while ensuring long-term reliability. After more than 12 months of rigorous testing, VF engineers resolved common issues like stalling and MAF errors found in other systems. Using the latest BMW file versions and proprietary flash technology, VF provides a clean and reliable method of software installation. The ECU software was extensively rewritten using VF's proprietary binary, assembly, and disassembly algorithms. The system underwent comprehensive road and dyno test cycles, including acceleration and deceleration tests to ensure drivability smoothness and optimal ECU fuel management. Test vehicles were subjected to long-term full-throttle testing in diverse conditions, from wet cold climates to the hot, dry Arizona desert, to monitor air-fuel ratios and knock activity. VF's expertly written ECU software allows the BMW engine to achieve over 40% more power in most applications, fully exploring the engine's potential and delivering an exhilarating driving experience. Upgrade your BMW Z3 with the VF-Engineering Supercharger System and enjoy a superior blend of performance, reliability, and engineering excellence.
