VF-Engineering chose to supercharge the BMW 3-series 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. VF have harnessed reliability of Vortech superchargers with their 15 years of supercharging experience and worldwide OEM supply contacts to create the ultimate supercharger system for the ultimate driver’s car.

The Vortech V3 Si-Trim self contained supercharger is mounted on a CNC machined 6061-T6 aluminum bracket system triangulated to the block. The unit is positioned in line with the original serpentine belt which is replaced with a longer OEM belt. The key to this design is that the OEM active-spring belt tensioner remains fully functional and eliminates belt slip or the need to manually tension the belt. The supercharger air ducts are custom molded polypropylene plastic to give an OEM appearance, quality and fit. The incorporated Bosch boost overrun system is designed for smooth off-throttle cruising and deceleration with clean emissions. The crankcase ventilation system is designed to cope with positive pressure. High flow fuel injectors are supplied to fit as direct replacements. 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.

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. VF sets up non-aftercooled kits at 6 psi and create as much, if not more power than similar products running greater levels of boost. The simplicity of this kit provides its greatest benefit: a large capacity supercharger unit running at low speed yields low temp air charge which in turn promotes optimal efficiency for a 45% power gain at the wheels.

Numerous M3 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. Software flash technology and latest BMW file versions have been combined to provide the cleanest and the most reliable method of end-user software installation using the optional “Hex-Flash” programming cable.
