See Audi, why did you phase out the 4.2-liter in the S5? You guys could have added a supercharger that would have made it so awesome.
By adding its Roots type supercharger kit, along with a stainless steel exhaust and reprogrammed engine management, the O.CT R8 pushes out an impressive 565 hp and 560 Nm (413 lb-ft) of torque.
“This values do not match the factory specifications, but are measured in O.CT test drives on real highways under real circumstances without any weight reductions etc. Herewith we can present values which can be reached in reality,” O.CT Tuning says.
The Austrian company has also shown a video of their work. The car is being tested on a dyno and it sounds like a combination of an American musclecar and one that’s been tuned in a video game like NFS. There’s plenty of screaming sounds coming from the exhaust, plus a few flames for added entertainment value.
