The Audi R8 GT is limited to only 333 units worldwide, so you can imagine that the chance to own one is pretty rare. For us, a base R8 GT is powerful enough from factory and it needs no upgrades. If you forgot, it is powered by a 5.2 V-10 engine that delivers a total of 560 horsepower and 398 pound-feet of torque. This amount of power is enough to sprint the car from 0 to 60 mph in 3.6 seconds and up to 198 mph.

But, what while we consider this amount of power quite enough for a sports car, the guys over Underground Racing decided the R8 GT can do much better so they developed a first upgrade package for it.

The kit is called Stage 2R Twin Turbo and was specially developed for a customer that opted for the FULL 2R build. This setup makes an easy 1,150 whp on 93 octane pump gas and more than 1,800 whp on race gas.
