E46 M3 Supercharger Essay
The VF-Engineering supercharger for the BMW E46 M3 S54 engine is the only water cooled supercharger system on the market. 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 3 stages of power, each stage up-gradable to the next, this piece of kit is for quality discerning enthusiasts only.
Based upon the Vortech V3 Si-trim Super Quiet unit, this unit is capable of supporting over 800hp. The centrifugal supercharger compressor maps ideally match the 8000 rpm revving S54 BMW Motorsport engine giving it a new meaning to high performance.
Machined from 6061-T6 aircraft grade aluminum the supercharger mounting bracket is triangulated to the engine block in addition to a Chrome Moly brace and grade 10.8 high tensile hardware. The factory belt tensioner is upgraded and the supercharger driven off an OEM quality multi-rib seperpentine belt. The factory plastic intake manifold is replaced with a VF cast aluminum plenum designed to channel the air from the supercharger to the 6 independent M3 throttle bodies. The VF plenum is designed to be upgraded with a slide-in high strength bar and plate heat exchanger for the upper 2 power level kits. The heat exchanger cools the intake air charge with isolated cold water circulating through it from a custom molded water reservoir, an OEM front mount radiator and water pump.
The high displacement bypass valve recirculates air charge off-throttle to minimize manifold pressure instantly. The bypass valve is mounted on a universal flange allowing you to opt for a blow off valve. The injectors are upgraded with high capacity Bosch EV14 high impedance quick response fuel injectors and calibrated by re-tuned software flashed into the ECU through the OBD2 port. Each power level is tuned with a specific custom calibrated software version.
Software is programmed into your ECU using the optional “Hex-Flash” programming cable. You can program your ECU in 15 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 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.

The intercooled S54 VT2-525 supercharger system produces 525hp and 340lb-ft of torque at 8psi of boost. A 192hp gain over stock, eclipsing the output of an E60 M5! Featuring the self contained Vortech V3 supercharger unit in Si trim, the supercharger is capable of producing up to 775hp.
The VT2-525 comes with a high capacity front mount intercooler (FMIC) and a specially developed cast aluminum intake manifold assembly with an integrated high capacity bypass valve designed not only for optimum flow, but for minimal weight to not disrupt the iconic chassis balance of the M3. The VT2-525 is a complete system with everything you need and is easily upgradeable as all the major hardware components are the same all the way up to our VT3-700.
The supercharger system includes the ESS E-Flash OBD2 cable and specific ESS engine software that is perfectly calibrated for the VT2-525 supercharged engine providing optimum ignition timing under all conditions, recalibrated throttle control for quicker throttle response, recalibrated VANOS control, and perfectly optimized fuel delivery. The dyno limiter and top speed governors are also removed. The E-Flash allows the end user to upload the supercharger ECU software from any PC running Windows XP or newer and includes a full diagnostic and code clearing capability. Any future ESS software updates can be received by email and loaded directly to the car. The stock ECU software will be saved and can easily be restored in the future.
Power delivery is 100% smooth and OEM-caliber. The car behaves just like stock until you demand power, then the car completely transform providing brutal acceleration normally reserved for pure race cars.
And like all ESS supercharger systems, the S54 VT Gen 3 kits are tested and tuned for over 50,000 street and track miles on multiple vehicles throughout the world, 60+ hours on our load dyno, full load top speed endurance testing on the German Autobahn, and final certification laps on the Nurburgring. The system maintains all OBD-II functions and it is backed by a comprehensive 2 year, unlimited mileage warranty program. This complete system is 100% bolt on and includes everything you need. Installation takes 6-8 hours using normal hand tools and no irreversible modifications to the car are necessary.
