The increase in power is due mainly to the fitting of an Eaton / Magnusson TVS 1900 supercharger, but also to an independent charge cooler system and an ECU remap. The force-fed V8 now pushes out 540 horsepower and 435 lb-ft (590 Nm) of torque, up from 350 lb-ft (475 Nm).
STaSIS also added a stainless steel, cross-flow exhaust system with reduced back pressure for improved power and efficiency. To improve handling, the car features lower springs while retaining the factory-installed “Drive Select” system. Other changes include larger brakes and 20-inch forged aluminum wheels fitted with high performance low profile tires.
The 28% power boost combined with an increase in weight of only 15 kilograms (33 lbs) over the stock Audi R8 V8, offers improved acceleration figures with 0 to 60 mph (96 km/h) coming in 3.6 seconds, 0.8 seconds faster than the factory model. It is also faster than the standard V10 version, which accelerates from 0 to 60 mph in 3.7 seconds.
The STaSIS Challenge Extreme Edition R8 V8 is available to buy as a complete package or as separate individual upgrades from the UK STaSIS agent network and from APS of Brackley. Prices have not yet been announced.
