Full Product Description

10 Hours fitting time, fully reversible.

VF-Engineering chose to supercharge the BMW E46 M3 to add to an already superior throttle response and give wild mid-to-top end power (sport mode) 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 drivers car.

VF purchased a 2005 model M3 (shown above) and chose to create a complete aftercooled stage 1 kit comprising of a production manufactured aluminum manifold with integrated air-to-water heat exchanger (charge cooler). 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 and giving cooler intake temperatures fot more powerful ignition.

VF has planned a (VHPD) Very High Performance Derivative stage 2. Aimed at the hard core enthusiast, this upgrade from the stage 1 package will include engine internal and lowered compression components. The VF demo car has been earmarked for conversion to be a 100% race car to show off this eventual flagship product.

All testing has been carried out on 91 octane Californian fuel and long term testing is currently being conducted in Summer 100+deg F temperatures. Product release is expected in Oct 2005.

All key components are 100% made in California. Supporting components such as injectors, radiators and water pumps are all aquired from German OEMs. 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 18 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. Competantly 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 sytem 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 3 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.

Above left: 2005 M3 engine installed with VF-Engineering stage 1 supercharger. Aluminum air/water cooled replacement manifold fits beneath stock stress bar and without any modification to stock components. Water lines are cleanly routed to and from the manifold and reservoir via a Bosch water pump.

Above right: (a) OEM water radiator fits under front bumper with no modfications at all. (b) Custom plastic molded ducting is used on all VF kits for ultimate quality and fitment. (c) Bosch injectors used fit as direct replacement without modification to injector rail. (d) CNC machined billet aluminum for superior strength and optical effect. (e) VF powder coated intake water cooled intake manifold.

Stage 1 Bolt-on 6.0 psi VF-Engineering supercharger with integrated chargecooler replacement manifold sytem. Target est 475hp at flywheel

Stage 2: Boost Increase to 7.5-8.0 PSI, replacement OEM belt tensioner upgrade, with custom GIAC Stage 2 Software flash and stage 2 fuel injectors. Tested with aftermarket headers and Euro catalytic convertor.

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.

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 GIAC 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. Power gains may vary according to factors such as altitude or vehicle condition.
