Audi R8 GT only make as many as 333 units, but there is one unit that is managed by a specialist kidnapped twin-turbo, Underground Racing. From the factory, the R8 GT is equipped with a 5.2-liter V10 engine that powered 560 hp and 398 lb-ft of torque, 0-60 mph acceleration in 3.6 seconds and a top speed of around 198 mph.
Thanks to Stage 2R UR Twin Turbo kit, the German supercar is now capable of spitting out more than 1,800 hp (race gas). So the above figures certainly changed quite drastically. Modifications made to the R8 GT include JRR Motec ECU Plug & Play system, full custom billet 1-6 ratio, billet shafts, billet final drive differential gears and billet helix. Visually, this silver-colored car body combined with a full black anodized billet intake and carbon fiber touches.
