With a heavy focus on sound engineering, VF offers the total package with reliability and power
VF-Engineering starts with the philosophy of their name: Engineering...
This kit for your athletic Z4M covers everything you need to seamlessly upgrade your power output in a linear and reliable fashion: from A-to-Z.
VFs kit allows you to supercharge your M-Roadster or M-Coupe to performance levels you never imagined! Add to the already superior throttle response of the S54, with wild power gains thanks to VFs enhanced ECU tuning, high quality parts, and the Vortech centrifugal supercharger... and you get one hell of an explosive package, but one that's also civil and reliable enough for daily use by anyone. That's where the VF difference is apparent.
Maintaining the original BMW quality, smoothness and reliability were the key factors in the VF design.
VF has harnessed the reliability of Vortech V-series superchargers. With VF's 10 years of supercharging experience and worldwide OEM supply contacts, they have created the ultimate supercharger system for the ultimate driver's car....
In late 2004, VF began to develop S54 supercharger technology and chose to create and test a complete aftercooled "Stage 1" kit, from there things took off.
A production cast aluminum manifold with integrated air-to-water heat exchanger (charge cooler) was custom developed for greater performance and clean looks under the hood. The latest version offers excelent performance as well as attractive esthetics.
Compared to similar air/air systems that are the common place solution; VFs air-to-water system is definetaly more costly for them to implement Typically used in professional Rally cars, and chapion drag race vehicles; air/water cooling is the ultimate in aftercooler technology for on and off the race track. VF does there best to implement this reliable technology at no cost disadvantage to you! Air/water cooling provides superior cooling ability over air/air without lengthy ducting that can cause complex ECU and tuning troubles and while creating a cooler intake temperatures for more powerful and reliable ignition.
The end result ? A system that is very clean and simple in its elegant installation and that the engine continues to drive and feel like an "M Car" while offering much more power with similar linear delivery, crucial to keep the cars excellent qualities intact.
All key components are 100% made in California. Supporting components such as flow matched injectors, radiators and water pumps are all acquired from German OEMs. 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 stage 1 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 and Siemens ECUs and resolved stalling and MAF issues faced by other supercharger systems. Software flash technology and latest BMW file versions have all been employed to provide the cleanest and the most reliable method of software installation. 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.
VF chooses the Vortech supercharger, mounting it with an in-house CNC machined aluminum bracket system. 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 in-house from 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 and high flow OEM 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.
Some facts about the VF kit versus the competition:
- The Vortech supercharger is a much larger unit and therefore has a superior flow rate over the competition.
- The Vortech unit [centrifugal] runs at approximately half the impeller speed when compared to a typical planetary unit at like-for-like boost levels.
- The Vortech unit is capable of creating up to 20psi [application dependent] and therefore has greater potential for higher power levels.
- The self-contained Vortech unit does not need its own separate oil cooling system with reservoir and extra radiator. Nor does it need to run off engine oil.
- Vortech units have been on the market for over 15 years in the US, many many times longer than the competition.
- VF's air/water cooling system is far superior to any air/air intercooler which is why VF makes 460whp on 91 octane without water/meth injection.
- VF's Stage2 makes the same power as the competitor kit but with less boost and less octane. VF only needs 8psi and 91 octane.
The VF supercharger system remains fully OBD2 compliant and is supported by a 1 year unlimited mileage warranty (on the kit only). Installation can be performed by most competent technicians in a true 12-16 hours and is non-intrusive, allowing it to be fully reversible.
Drag racing and aggressive back to back peak rpm shifting with the higher stage levels will likely require a clutch upgrade. 100 octane fuel recommended when used on the race track. A pre-cat wideband air/fuel ratio monitoring gauge is recommended.
- There are 2 levels of bolt on supercharger kits available, Along with our custom VAC "4th stage" to fit all power levels and budgets - Each kit is upgradeable to the next as you grow:
VF420 Supercharger System (NLA - listed for reference)
Setup for 4.0-4.5 psi V3-SC trim supercharger system (non aftercooled). Replacement cast intake manifold prepared for aftercooler cartridge. Everything needed is included, as well as a custom ECU flash*. Easy to upgrade to stage 1 'VF480'. Great for those on a budget!
Expect power in the 350whp range on 91 octane (AKI) pump gas
VF480 Supercharger System, aftercooled (NLA - Listed for reference)
Setup for 5.5-6.0 psi, V3-SC trim supercharger along with VF's air/water cooled cartridge (aftercooler) inside their cast intake manifold. A High flow fuel system with VF Stage 1 injectors and custom ECU flash. Once again, an easy upgrade to stage VF580 is available.
Expect power in the 400whp range on 91 octane (AKI) pump gas

Not all vehicles respond identically to engine modifications which is why it is important to consider the "delta", or relative power increase, measured on the same dyno before and after modifications. Power gains shown on the bolt on VF kits have have been found to be accurate on test vehicles on 91 octane at sea level. VF does not guarantee that all engines will make the same power numbers. The custom software adapts just as the OEM software and a slight increase in performance may be expected from the use of higher quality fuels such as 93 octane. Power gains may vary according to factors such as altitude or vehicle condition. VF installs its systems in house as means of continuous product monitoring. All vehicles are dyno'd pre-install and the stock E46 M3 typically delivers 265-275whp on 91 octane. VF-Engineering is not responsible for pre-existing or consequential wear and tear of your vehicle. It is an assumed owner responsibility to ensure your car is adequately upgraded to support power enhancements.
VF's testing of EGT and wide band O2 was performed from sensors installed in the OEM header. Technicians logged individual cylinder exhaust gas temperatures as well as Air/Fuel ratio in each exhaust bank (pre-catalytic converter).
