Audi is one of those automakers we love writing about. It's even better when there's a tuning firm out there that knows how to make an already incredible car even better. This is what Underground Racing did with the Audi R8 and its tuned variation called R8 V10 Twin Turbo. This American tuning firm has managed to bump the horsepower output of this Audi to a staggering 1000 + horsepower.
All this power comes courtesy of the twin turbo engines that come with the tuning package for the R8. This 5.2-liter V10 engine is also the same V10 that they have used in the Lamborghini Gallardo. Besides those bits of information, the tuner is largely silent about what else the package includes, so enjoy the pictures.
