VF-Engineering is the first to develop and build a supercharger kit with true OEM quality and drivability. It is also the first truly do-it-yourself and reversible conversion kit, using the famous "bullet proof" Vortech Engineering supercharger unit. The key to the design of this supercharger kit is the simplicity with which it can be bolted on. The kit is supplied with every part needed to get your car up and running supercharged on the same day.

The R32 is a special model, a derivative of the highly successful Volkswagen VR6 engine used from the early 90's evolving from the 12v cylinder head version to a 24v head designed by Cosworth. The R32 is endowed with a capacity 3.2 liters up from the standard 2.8 liter VR6. With further increased compression, this motor now achieves a base power of 240hp up from the original VR6's 170hp. The VF-Engineering stage 1 supercharger conversion adds about 80hp to the R32 and 110hp with stage 2 which uses an air to air high-flow front mount intercooler.

Although similar to the European model, the US R32 model has proven to be a challenge for tuning with low quality fuels. After three months of development in early 2004, VF-Engineering in conjunction with GIAC completed a system which raises the already powerful R32's horse power by an astounding 36% at the wheels! All testing and development was performed with Californian 91 octane gasoline and dyno numbers reflect this. 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 3.2 engine. In tests using higher octane pump gasoline, power output increased by an additional 5% and even higher with high octane race fuels.

Performance, reliability, and stock feel are major factors in the extensive R&D carried by VF-Engineering in Europe and the USA. The custom proprietary VF.GIAC software supplied with this kit safely re-aligns all fuelling and engine management parameters. Unlike other forced induction solutions, VF-Engineering's kit is designed to work safely within Volkswagen's OEM parameters thus minimizing the likelihood of spurious DTCs (Diagnostic Trouble Codes) or Check-Engine Lights.

The Volkswagen VR6 engine was designed as a GT Grand Tourer. With the VW variable intake design the normally aspirated power of the R32 is accentuated in low rpm. However there is a noticeable lack of acceleration in the higher rpm band. This is where the VF supercharger really kicks in, keeping the shape of the power curve but raising it all the way to the top.

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 chassis dynos produce comparable results 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, with stock setups (i.e. throttle body, exhaust system, cams, 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.

VF-Engineering R32 stage 3 (total power increase +210hp, +140ftlbs) - Development:
VF began testing high boost systems on the R32 with up to 20psi manifold pressure on its "Project 500" belonging to "QBNR32". Development began in early 2005 and took over a year. Equipped with a larger Vortech V1 SC straight cut gear unit running a Gates "Power Grip GT2" cogged belt, it made 508hp (580 flywheel hp) at the 2 front wheels on the VF Dynojet and 440whp on a Mustang 4wd dyno (all with stock clutch). This car certainly opened up the playing field with competing turbo kits.

The success of Project 500 showed that Supercharged power could reliably more than double horsepower. VF attributes the linear-like power delivery characteristics of the centrifugal supercharger to the fact that all testing was performed with a stock clutch, catalytic converters and camshafts on 91 octane.  

Final Track Testing is complete...

Stage 3 - Stage 2 is a pre-requisite for the stage 3 upgrade. Race bypass valves are highly recommended and must be purchased additionally with the stage 3 upgrade package and are priced separately as many stage 2 owners may already have upgraded them. VF-Engineering's engine mounts are also mandatory to keep the engine in place and restrict excessive movement of the motor during hard acceleration. VF recommends a stronger clutch for arduous and track-type driving conditions (stock clutch will suffice for street use). Bigger brakes and stiffer suspension are plus points giving the driver the assurance to exploit the power. The Stage 3 car is pretty radical considering it was designed as a daily driver and "even one's wife could drive it". It idles like stock and part throttles with great urgency, but when you stomp on it, traction becomes an issue. For an out-of-the box kit, we believe its hard to get better value. 450hp and 370ftlbs for $9000. This is Vortech supercharged power at its best.

Understanding Dyno Charts

I can't thank you enough for the excellent job you did on the stage 2 supercharger you installed on my R32. You took my great car and made it an amazing car! It is a blast and puts a smile on my face every time I start my car and hear the hum of the blower under the hood. Also when you complete the stage three, put me on the top of the list for the upgrade. - Justin S. (Long Beach, CA. Aug 04)

With over several hundred R32 supercharger systems sold and supported throughout the world, it is needless to say that the repuation of this kit speaks for itself and sets the benchmark for forced induction. The quality and build of all VF systems is clearly apparent from the moment you open the box to the time you step on the gas pedal. VF and GIAC engineers have spent countless hours perfecting the R32 kit in all conditions to satisfy the most discerning of enthusiasts. - Nik Saran (Head of VF-R&D, Aug 05)
