Usually when people think of Underground Racing, they're liable to think of extreme tuning kits for Lamborghini and Ferrari models because that's what they are used to seeing. However, about a year and a half ago, Underground Racing announced the beginning of a tuning project for the beautiful Audi R8 V10, and now that kit has come to fruition in four different stages.

The new Audi R8->ke1440 by Underground offers three different twin turbo engine upgrades, as well as a Race Version, to satiate the speed desires of R8 fanatics. The first stage will raise the output to 700 WHP on pump gas (93 octane) or 1,000 WHP on race fuel for a bargain price of $39,000, while the second stage puts out 850 WHP on pump gas or 1200 WHP on race fuel for $69,000. The final standard stage will take power up to 1,000 WHP on pump gas and 1,200 on race fuel for a whopping $94,000.

Now, if anyone is prepared to pay close to the base price of another R8 V10, then the Race Version kit is up for grabs for a staggering $109,000. This ultimate tuning upgrade will take the standard 525 HP up to 1,000 WHP on pump gas and a killer 1,500 WHP on race fuel.

Hit the jump to watch the 1000 WHP version in action.
