VF-Engineering supercharged the BMW E92 M3 to create beastly power from this end of the world production high revving V8. Maintaining 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 to create the ultimate supercharger system.
The VF-Engineering M3 supercharger for the BMW E90/92/93 S65 engine is a fully upgrade-able water cooled supercharger system. Designed to provide the most consistent charge temperatures under aggressive driving, the VF water intercooler system has a greater propensity to dissipate heat energy out of the air charge than an air intercooler.
VF use state of the art production manufacturing processes to create the highest quality supercharger kit on the market. A supercharger system designed with 4 stages of power, each stage up-gradable to the next, this piece of kit is for quality discerning enthusiasts only.
VF-Engineering chose to build this kit with the most efficient Vortech unit available – the V3 Si trim. Its super quiet helical cut gears make it super stealthy yet still remind onlookers that there is something different under the hood. The Si trim supercharger delivers a bigger mid range punch than the race “T-trim” yet is capable of supporting over 700hp. The centrifugal supercharger compressor maps ideally match the 8300 rpm revving S65 BMW Motorsport engine.
VF-Engineers created hardware that most would consider to be an “overkill” when compared to other kits. Just looking at the CNC Machined supercharger bracket, the flycut 6061-T6 aircraft grade aluminum is not only the stiffest on the market but also something that you could expect to see used in the aerospace industry. This mounting bracket is a triangulated to the engine block in addition to a rigid Chrome Moly brace and with high tensile hardware.
The factory belt tensioner is upgraded and the supercharger is driven off an OEM multi-rib serpentine belt. The factory plastic intake manifold is replaced with a high VF cast aluminum plenum designed to channel the air from the supercharger to the 8 independent M3 throttle bodies through tapered velocity stacks designed to speed up airflow. The VF plenum is designed to be user-upgradable with a the VF slide-in high strength bar and plate heat exchanger for the next 3 stages of power. The heat exchanger cools the intake air 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.
M3 Tuning software is programmed into your ECU using VF’s “Hex-Flash” programming cable. You can program your ECU within minutes yourself through the OBD2 connector on your dashboard. This tool also allows you to read and clear ecu codes.
Optional software features include:
- RPM limiter. On request we can provide a higher rev limiter software file.
- Cold start. Cold start loud start can be switched off upon request.
- Performance Exhaust. High performance exhaust compatible tune option upon request.
- 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).
