VF-Engineering chose to supercharge the BMW 323 and 325 to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger. Maintaining the the original BMW quality, smoothness and reliability were the key factors in the VF design. This is where the GIAC software comes into full play. VF have harnessed reliability of Vortech superchargers and quality of GIAC 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.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. GIAC 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. Installation can be performed in approximately 8 hours and is non-intrusive, allowing it to be fully reversible.Kit Components: GIAC custom tuned software RPM limiter increased Soft rev limiters and top speed governor removed Vortech V2 Super Quite SC trim polished supercharger 1 year unlimited mileage limited product warranty VF- CNC machined 6061 aluminum bracket system OEM BMW idler pullies OEM High flow fuel injectors VF- Custom molded polypropylene ducting VF- Custom tuned supercharger intake Bosch overrun bypass valve system Custom crank case ventilation system 4 ply silicon couplers with OEM screw clamps VF- CNC oil fittings with high pressure OEM oil lines Replacement OEM serpentine belt K&N induction filter with cold air intake and optional air box Comprehensive installation CD-ROM Compatible with automatic transmission (please specify) Precision Made in California, USAStock Performance:BHP - 170Torque - 181Superchargered performance:BHP - 271Torque - 235This Product FitsBMW E46 323 99>00 M52-TU-B25 2.5 liter engine MS 42.0Please allow 2-3 weeks delivery

VF-Engineering chose to supercharge the BMW 328 and 330 to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the 3.0 liter version being a bored and stroked upgrade of the 2.8 motor, both variations are otherwise virtually identical. Maintaining the the original BMW quality, smoothness and reliability were the key factors in the VF design. This is where the GIAC software comes into full play. VF have harnessed reliability of Vortech superchargers and quality of GIAC 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.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 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.

VF-Engineering chose to supercharge the BMW E46 M3 to add to already superior throttle response and give wild mid-to-top end power (sport mode) with the centrifugal Vortech supercharger.Maintaining the original BMW quality, smoothness and reliability were the key factors in the VF design. This is where the GIAC software comes into full play. VF have harnessed reliability of Vortech superchargers and quality of GIAC 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.In late 2004, VF purchased a 2005 model M3 (black M3 shown above) and chose to create and test its complete aftercooled Stage 1 kit. A production manufactured aluminum manifold with integrated air-to-water heat exchanger (charge cooler) is provided for added value and greater performance compared to similar air/air systems. Typically used in European Rally cars, air/water cooling is the ultimate in aftercooler technology for on and off the race track. Air/water cooling provides superior cooling ability over air/air without lengthy ducting while creating cooler intake temperatures for more powerful and reliable ignition.The E46 M3 Stage 2 kit [released Feb 08] offers even greater performance via extra boost from a smaller supercharger pulley, replacement stiffer serpentine belt tensioner and upgraded GIAC stage 2 software ECU flash with larger stage2 fuel injectors and MAF upgrade. This kit requires the use of high performance cats. The test car was setup with Supersprint headers and Euro M3 cats. Drag racing and aggresive back to back peak rpm shifting 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.The Stage 3 test car was setup with a rebuilt low compression motor and extra boost from an upgraded T-trim supercharger delivering 15 psi driven from a replacement increased diameter crank pulley. Upgraded GIAC stage 3 software ECU flash and fuel pump upgrade completed the enging management calibration. There is no planned public release for the stage 3 until long term test results have been approved. Beta kits are currently being installed in house.

VF-Engineering chose to supercharge the Audi R8 to improve throttle response and mid-to-top end power with a roots type Magnuson/Eaton TVS 1900 supercharger. Maintaining the the original Audi quality, smoothness and reliability were the key factors in the VF design. This is where the GIAC software comes into full play. VF have harnessed reliability of Eaton superchargers and quality of GIAC 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.All key components are 100% made in California. This system has been fully road tested, documented on multiple race tracks and dyno tuned on GIAC's Mustang MD500AWD. The Audi R8 supercharger kit is setup at 7.5 psi and creates as much, if not more power than similar products running greater levels of boost.VF engineers spent over 12 months testing and developing the Audi R8 supercharger kit. Software flash technology and latest Audi file versions have all been employed to provide the cleanest and most reliable method of software installation. GIAC 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. One of the interesting features of the software recalibration we provide, is the development of software "switching". Using a small handheld unit that the user can plug into the OBD2 port, the software can be switched on the fly through different modes such as "Race gas" higher timing program for when you fill up with high octane, or "Valet mode" to reduce power for obvious reasons. The GIAC software is electronically "flashed" into the ECUs through the OBD2 port with the optional modes. Our R8 supercharger system will included the fully loaded GIAC features. All test cars were put through long term full throttle testing in conditions varying from wet cold climates to hot dry race track conditions for safe-optimal air fuel ratios and knock activity monitoring. Competently-written ECU software has allowed VF to fully explore the potential of the Audi R8 engine.VF chose to mount the Eaton TVS 1900 supercharger with an in-house CNC machined billet aluminum housing containing an air/water heat exchanger. Our approach to the supercharger development is quite unique when it comes to design and production style. With a higher bar set for this project, our engineers chose to use the latest supercharger from Eaton Corporation: Twin Vortices Series TVS 1900. It is a 6th generation 4 lobe roots supercharger that supercedes the older 3 lobe MP90 and MP112. With the ability to rev to higher bearing speeds for longer periods, the TVS 1900 unit can be operated at lower speeds than the older unit and create more boost due to its displacement and higher efficiency. The supercharger is mounted atop the motor and driven off an upgraded Goodyear serpentine belt system and heavy duty active belt tensioner. The stock belt has been upgraded from 5 to 7 ribs. The VF supercharger system remains fully OBD2 compliant and is supported by a 1 year unlimited mileage warranty on the product only.Kit Components: GIAC custom tuned software Soft rev limiters and top speed governor removed Magnuson/Eaton TVS1900 satin black supercharger 1 year unlimited mileage limited product warranty VF- CNC machined 6061 aluminum bracket system OEM Good Year idler pullies VF- Custom tuned supercharger intake Internal overrun bypass valve system OEM crank case ventilation system Replacement OEM serpentine belt Comprehensive installation CD-ROM Precision Made in California, USA Stock Performance:BHP - 420 Torque - 317Superchargered performance:BHP - 458Torque - 437This Product FitsAudi R8 4.2 liter V8 mid engine Watch the videos:http://www.youtube.com/watch?v=5FPK61A1_TU&feature=player_embeddedPlease allow 2-3 weeks delivery
With more than 12 years experience in the forced induction industry, it was a natural progression for VF-Engineering to branch out and supercharge the naturally aspirated Audi S4 being a prime candidate for an FI upgrade, VF's relationship with GIAC USA, along with its use of state of the art technology, coordinate measuring machine (CMM) and Superflow air flow bench testing technologies set a firm foundation for that the ground work VF has committed for the Audi S4.VF-Engineering chose to supercharge the Audi S4 to improve throttle response and mid-to-top end power with a roots type Eaton MP90 supercharger.
