With a heavy focus on sound engineering, VF offers the total package with reliability and power

VF-Engineering chose to supercharge the BMW 740 to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger unit. Maintaining the the original BMW quality, smoothness and reliability were the key factors in the VF design. This is where VF's software comes into full play. VF have harnessed the reliability of Vortech superchargers and quality of custom software with their 10 years of supercharging experience and worldwide OEM supply contacts to create the ultimate supercharger system for the ultimate driver's car.
A supercharged 740 has the looks and refinements one expects from a high-end BMW saloon but is a true autobahn terrorist to the unsuspecting eye!

 

All key components are 100% made in California. This system has been fully road tested and dyno tuned on both the GIAC 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 most reliable method of software installation. Engineers extensively re-wrote the ECU software using their own binary, assembly and disassembly algorithms written from scratch. Testing the software included extensive road and dyno test cycles, with acceleration and deceleration tests for driveability 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 chose to mount the Vortech supercharger 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. The VF supercharger system remains fully OBD2 compliant and is supported by a 1 year unlimited mileage warranty on the product only.

Some other facts about the VF kit versus the competition:

  1. The Vortech supercharger is a larger unit than others, with a superior flow rate over the competition.
  2. The Vortech unit [centrifugal] runs at approximately half the impeller speed when compared to a typical planetary unit at like-for-like boost levels.
  3. The Vortech unit is capable of creating up to 20psi [application dependent] and therefore has greater potential for higher power levels should you chose to upgrade in the future.
  4. The Vortech unit does not need an external oil system with reservoir and extra radiator, nor does it tap into the OE oil system.
  5. Vortech units have been on the market for over 15 years in the US; many, many times longer than the competition.

Three individual kits for each generation of E38 made:

1996-1997 E38 740 i & iL (4.4l M62)
Bolt on "ready to run" 6.0 psi VF-Engineering supercharger system
[VF Part # VFK42-01]

Figures: PSI: 6.0 / HP: 415 / Torque: 400

1998 E39 E38 740 i & iL (4.4l M62)
[VF Part # VFK41-01]
Figures: PSI: 6.0 / HP: 415 / Torque: 400

1999-2002 E38 740 i & iL (4.4l M62tu)
[VF Part # VFK21-01]
Figures: PSI: 6.0 / HP: 415 / Torque: 400

10-14 Hours fitting time, fully reversible.

Every aspect of this kit has been fully engineered for high quality fitment and highly demanding performance and expectation. VF's in-house horizontal, turning and milling CNC's and plastic molding plant, GIAC's industry reputation and track record, and Vortech's reliability have been fully exploited to create a product with internationally un-rivaled material technology, quality, and performance.

--Notes for CA Residents:
This product is not compliant with California Air Resource Board (CARB) and not intended for use on public roads in California. This applies to any aftermarket product that does not display a CARB Exemption Order Number (EO#) wich includes most supercharger systems. Please inquire if you need clarification 

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 modification. 

Power gains shown by VF have been found to be accurate on test vehicles on 91 octane at sea level, with stock setups (ie throttle body, exhaust system etc). The VF 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. 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). 

Note that Dyno measurements / power figures are made from vehicles with manual transmissions for accuracy; power gains may vary according to factors such as altitude or vehicle condition.
