VF Engineering - R8 VF550 Supercharger Kit
Bolt on "ready to run" 6.0-7.0 psi 548HP 437TQ!!
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.
