Slideshow: Underground Racing Twin Turbo R8 is a Beast

A mere decade ago, calling a car with 800 horsepower “modest” would be laughable. Today, it’s just as common as filling up your gas tank.

Underground Connections

If you aren’t familiar with this company, here’s a brief introduction. Underground Racing has been turbocharging Lamborghini Gallardos and Audi R8s since Kevin Howeth got the itch to start doing something different. The cars they tune have quickly become some of the fastest standing mile competitors in the world.

“Entry Level”

Entry level tuning packages for the R8 start at 800whp while boasting this incredible performance on 93 octane fuel. The stock ECU is utilized as well which shows how much potential there is in working with factory technology. Lamborghini really does build these cars to last with a generous power ceiling in reserve (ok, adding two turbos does help).

Super Speed

All of this is good for some seriously fast acceleration: an 800whp R8 from Underground Racing will comfortably run the quarter mile in the 10-second range without ever breaking a sweat. See one of these cars prowling around on the company’s base in North Carolina and you’re best off leaving the beast alone. These cars put down some of the fastest cars in the world.

Pennies on the Dollar

Maybe to the people that buy these kits! To the rest of us, the cost involved with these types of projects could pay off a home. One of these simple 800hp turbo kits will run you $49,000 but don’t worry, it includes installation. Other components in the car have to see excess stress, so it would be interesting to see how long one of these cars can be abused before other parts start tearing themselves to pieces.

No Longer Substantial

Thanks to the internet, cars with 800 horsepower no longer excite us. There once was a time when these power levels were only reserved for the fastest of race teams. This is no longer the case with aftermarket tuners pushing the limits to staggering heights. Underground Racing routinely builds cars that eclipse the 2,000 horsepower mark and have even started pushing some cars into the 3,000hp territory. 800hp is fast, but it’s more of a start point now and that is truly the craziest part about these beasts.
