BMW E46 M3 2001-2006 |VF Engineering Supercharger VF420 | Crown Auto Performance
he VF-Engineering M3 supercharger for the BMW E46 S54 engine is a fully upgrade-able water cooled supercharger system. Designed to provide the most consistent charge with the cooled water circulating through it from a custom molded water reservoir, an OEM front mount radiator and water pump. The optional “Race” version water radiator is offered for track and aggressive drivers.
The high displacement bypass valve recirculates air charge off throttle to minimize manifold pressure instantly. The bypass valve is one of the largest available valves in that frame. Mounted on a universal flange, the VF valve can be replaced with an optional “Tial” blow off valve for superb sound effects.
The fuel injectors are upgraded with high capacity Bosch EV model high-impedance rapid response fuel injectors that were carefully chosen and tested for exacting response time and ultra-precise spray pattern. These injectors match the OEM fuel pattern and provide optimal combustion and superior fuel efficiency but with significantly greater horsepower potential.
Featuring nearly twice the flow rate, these injectors are calibrated with proprietary software flashed into the ECU through the OBD2 port. The flashing can be easily performed by the installer with a programming cable and a software file emailed to you. Each power level is tuned with a specific custom-calibrated software version.
This meticulous choice of fuel injector and software integration is one of the key components in the VF supercharger system. Combined with efficiently written ECU supercharger code, the precise fuel atomization of this Bosch EV14 high flow injector allows critical fuel trimming to match the ECUs processor requests.
Ultimately it’s just one of several reasons why VF Engineering has been the gold-standard in supercharger systems for more than a decade.

System Validation and Vehicle Requirements:
This supercharger system was designed and validated on a stock vehicle fueled by 91 octane Power gains achieved on stock motor with OEM components Dyno results may vary due to environmental conditions and measurement tools Prior to supercharger installation the vehicle must be programmed and operating on the stock ECU file
Our tuned ECU file is built on the stock read out, previously “tuned” ECUs will need to be programmed back to stock.
Optional software features include:
RPM Shift lights activation for manual transmission vehicles. Manual cars can now experience the OEM shift lights on the RPM counter that the SMG vehicles already feature. SPORT Button Memory. You have a choice of requesting to have the sport button permanently selected to Sport mode or you may opt to have the memory feature activated which keeps the sport button in the mode that the car was switched off in. You can keep it in Sport mode all the time (even after switching the car off) but can still switch it off.
Race Gas software. If you plan to use higher octane fuels, we can supply optimized software for higher octanes giving the benefit of added horsepower.
Independence. You may re-install your stock program at any time at your convenience. You may also program upgraded custom race gas files (available optionally from VF).
Valet mode/Immobilizer. If you are going to leave the car unused for a long period, you may wish to program our optional Valet Mode file or Anti-theft file.
