The Texan brothers from Underground Racing sure like making things go fast. Super fast. It seems to be in their bloodline considering they come from a family of stock car and drag racers, but they take it to another level.

After seeing a 1500 HP Lamborghini Gallardo, Underground Racing is teasing us with the idea of an Audi R8 V10 delivering the same amount of power. We don't know how much of this we can handle, but we are thrilled to give it a shot. The tuner has prepared four different stages for the R8 V10.

First, with the use of a custom turbo system, the engine delivers an impressive 700 HP. The price for this update is $39,000. In Stage 1 (Turbo System with Modified Engine), the V10 engine delivers 850 HP, but you'll have to pay $69,000 if you want this upgrade.

In Stage 2, the engine goes to an impressive 1000 HP and as the horsepower increases so does the price; set at $94,000.

And finally, if you have an extra $109,000 burning a hole in your pocket, we highly recommend the Stage 3. The Stage 3 modification takes the output of the Audi R8 V10 to an impressive 1000 Hp (or 1500 HP on race fuel).
