VF Engineering Supercharger E38 740i up to 1998

Maintaining the the original BMW quality, smoothness, and reliability were the key factors in the VF design. This is where the VF software comes into full play. VF have harnessed reliability of Vortech superchargers and quality of VF custom software with their 15 years of supercharging experience and worldwide OEM supply sources to create the ultimate supercharger system for the ultimate drivers car.

All key components are 100% made in California. This system has been fully road tested and dyno tuned on both the Mustang MD500AWD and in-house Dynojet 224XLC dynamometers with and without engine load. All kits are setup at 6 psi and create as much, if not more power than similar products running greater levels of boost.

VF engineers spent over 12 months software testing the BMW Bosch 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 an optional DIY programming cable and email-able software. Testing the software included extensive road and dyno test cycles, with acceleration and deceleration tests for driveability 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.

VF chose to mount the Vortech supercharger with CNC machined T3 anodized aluminum 6061-T6 bracket system. The unit is positioned in line with a bolt-on crank pulley with an additional active OEM tensioner using a dedicated serpentine belt. The key to reliable superchargers systems is the active belt tensioner which eliminates belt slip. The supercharger air ducts are custom molded in-house from polypropylene plastic to give an OEM appearance, quality and function. The incorporated Bosch boost overrun system is designed for smooth off-throttle cruising and deceleration. The crankcase ventilation system is designed to cope with positive pressure and high flow fuel injectors are supplied to fit as direct replacements without modification to the injector rail.  A removable plastic air box is provided with the K&N induction filter for those who use their vehicles in persistently wet climates.The VF supercharger system remains fully OBD2 compliant and is supported by a 1 year unlimited mileage warranty on the product only. Installation can be performed in approximately 8-10 hours and is non-intrusive, allowing it to be fully reversible.

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.
