xXx-Performance from Bochum and Chiptrick technologies from Wuppertal jointly placed the Audi R8 project vehicle shown here, on four wheels, which impressively underscores the amount of power that can be potentially teased out of the 4.2 FSI drive mechanism. For this purpose, Chiptrick developed the company’s own Biturbo system which forces the respiration of the V8 with two specially constructed Garret turbo chargers and tailor-made charge-air cooler and also contains amongst others, a high-pressure fuel pump and more efficient injection nozzles. The covers of the charge-air cooler are optionally obtainable in red, black or carbon optics. Moreover, there is the company’s own self-developed exhaust system with cross x-pipe and valve control system on board for the technically adequate disposal of the hot combustion waste gas, which controls all tonalities and volume levels from the decent piano up until the unrestrained fortissimo. Vehicles with the sequential R-tronic 6-gear manual transmission are moreover upgraded with a special transmission software that is adapted to the new situations.
Depending on customer’s requirement, the Biturbo system can also be obtained in three performance stages: In stage 1, the performance of the R8 4.2 FSI surges from 420 to 590 horse power, the torque increases from 430 to a whopping 660 Nm. Already in this configuration, the turbo R8 easily outshines its bigger brother in standard production R8 5.2 FSI quattro (525-550 horse power / 530-540 Nm). The medium class turbo upgrade stage thus has 640 horse power and 675 Nm and the current top version unleashes a whopping 707 horse power and a powerful 809 Nm. In its biggest upgrade version, the Biturbo R8 is catapulted to 100 k.p.h. in just 3.6 seconds – one whole second faster than the standard vehicle. The 200 k.p.h. limit plunges to 10.6 seconds and only 15.8 further seconds later, the speedometer needle crosses the 300 k.p.h. check mark. The electronic system terminates the propulsion only at 313 k.p.h. In spite of the enormous power boost, Chiptrick and xXx-Performance while developing the turbo technology, paid special attention to the sound drivability and suitability for daily road use as well as durability of the entire system. The Biturbo system will be henceforth produced in small batch series and will be obtainable from cooperation partners. Even TÜV gave its blessing to performance stages 1 and 2 while stage 3 is only obtainable as export version.
