Underground Racing’s Ferrari 458 Italia has been twin-turbocharged and packs 700-whp. Lamborghini‘s Aventador LP700-4 delivers 700-hp from the factory, so obviously it makes perfect sense to pit the two Italian exotics against one another in one awesome video.

Though the “racing” in the video isn’t exactly perfect in terms of judging which vehicle is truly better or faster, it’s worth watching to hear the sonorous note of two if Italy’s finest exotics.

The 458 features Underground Racing’s Stage 1 bolt-on turbo kit taking the factory 562-hp to a 700-whp on 93-octane pump gas. If you’re not aware of just how big a difference there is between 700-hp and 700 horsepower at the wheels, this video should clear things up pretty fast.

Underground Racing has promised a rematch of the two in the near future, just as soon as it preps a twin-turbo setup for the Aventador’s V12.

What to do with a twin-turbo Lamborghini Gallardo? That’s the question Robert Himler asked himself after getting his Italian exotic back from Underground Racing, once they completed a 1,250-whp build on the car.

Race a jet? Impress the ladies? How about: scare the sh*t out of his mom. And that’ sjust what he did, installing a Go-Pro camera on the dash to document the spirited ride through the city. And the reaction from her is, well, priceless. In fact, it’s quite hilarious, mostly because it’s what we’d expect all our moms to do if we ever had the opportunity to do the same.

Check out the awesome video after the break.

Amidst all the OEM built and sponsored vehicles at SEMA are a few privately owned gems, commissioned by their owners from some of the top aftermarket shops in the country. We stumbled across one such creation at the Mobil 1 booth.

As though the Lamborghini LP670-4 SuperVeloce wasn’t potent enough, one speed freak decided to ship his car to Underground Racing, where the experts in turbocharging high-horsepower engines really took this Lambo to an all new level. Thanks to twin-turbochargers, the 6.5-liter V12 engine gets a bump from 670-hp to more than double at 1,400-hp. The entire engine was rebuilt from top-to-bottom, custom twin-disk carbon clutch is used to stand up to all that horsepower and a Motec ECU handles the fuel and spark.

Little else was done to the car (what else needs to be) with a nice set of HRE 798R wheels adding a little extra style to the wildest of Lambos.

We’re excited to see the first videos of this car blasting down the quarter mile or even demolishing the stock car’s 212-mph top speed.

Underground Racing’s Twin Turbo Lamborghini Gallardo Superleggera is no stranger to internet fame. We reported when it broke the 250-mph park out at the Texas Mile and now we’re sad to report that the vehicle suffered a momentous wreck, rendering it totaled. Luckily the driver was able to walk out on his own safely.

It’s a no-brainer that testing your vehicle to excess of 250-mph speeds can be dangerous. But it’s great to see what the safety of the driver was still a priority when building this high horsepower exotic. The Gallardo did several flips before it came to a stop, and clearly started to flip at still a high rate of speed.

There are contradicting reports on what really caused the accident, but we think it’s not even worth arguing over – so long as someone figures it out on future high speed exotic builds. We’re just glad the driver walked away safely.

After building a twin-turbo Lamborghini LP640 that laid down 1000-hp, Underground Racing has just announced even bigger and better things for the LP670-4 SV.

Rumor has it that Underground Racing wants to claim the title of fastest Murciélago in the world with this LP670-4 SV. Their engineers are claiming that they’ll be putting down 1,100-hp out of this beast. We’re guessing it won’t be long until we feast our eyes on dyno videos and some high-speed runs. And to top it off, we’re digging the fact that this LP670-4 SV is paired up with a set of HRE Wheels; anything less on an 1,100-hp Lamborghini would be blasphemous.

Sometimes it’s hard not to be jealous at those lucky enough to own exotics from Ferrari or Lamborghini. It’s natural, we understand. But we gotta say, it’s extra tough when we see a Ferrari owner that’s able to take their F430 over to Underground Racing, pick out a twin turbo kit and throw down 1,000-hp.

This isn’t the first time we’ve been entertained by a video starring Underground Racing’s vehicles. Instead of a Lamborghini though, this time we’re treated with some exciting footage focused on the 1,000-hp creation. The video does a fantastic job highlighting the car itself and takes us through some of its dyno runs where we can hear the V8 in all its pure, unadulterated glory. Feast your eyes and ears guys and gals, this is the true way of owning an exotic.

In March of 2009, we reported several exotics that broke the 200-mph barrier out in Florida. Underground Racing was one of those exotic tuners that were on hand including several of their twin-turbo Lamborghini Gallardos. A little over a year later, Underground Racing has surprised the world in a story that makes everyone just a little bit jealous.

Underground Racing has built a huge reputation of applying twin-turbo kits to many of the world’s fanciest exotics including Lamborghini’s Murciélago and Gallardo, Ferrari’s F430, Dodge’s Viper, Ford’s GT and Audi’s R8. Much of its goal is to break the 1,000-hp mark on certain applications, meanwhile being notorious for tackling the mile-straightaway at blistering speeds.

Earlier in March, they took a Lamborghini Gallardo Superlegerra, tossed on their trademark twin-turbo kit and proceeded to blast away at 250.1-mph at The Texas Mile after rigorous tuning and testing of turbo and suspension configurations. Your eyes do not deceive you, this exotic bull flew past the competition in attack mode while still enjoying air conditioning and the stereo blasting while waiting at the line. Owner and driver Richard Holt could never be happier.

Make sure to check out the video that just surfaced this week, sporting three different views, after the jump.

The Underground Racing Lamborghini Gallardo has it all. On display at the Mobil 1 booth, the Italian exotic not only sports a matte-black paint job, but it’s what’s under the glass engine cover out back that will really get your attention.

There you will find what Underground Racing has become famous for, a twin-turbo kit. The North Carolina tuner builds each twin-turbo application specifically to the needs wants of the customer, with output ranging from 1,000-hp to 1,500-hp. And don’t think it’s as simple as two big turbos and some shiny metal piping either, the team at UR will tear down and rebuild an engine to ensure maximum performance and longevity, with new cylinder heads, CP Race Pistons, Carrillo billet con rods and lots of other hard core parts.

The result, claims UR, is a 0-60 mph time of just 2.5 seconds, with a quarter mile pass taking just 9.1 seconds at 169 mph! The company also claims a speed of 241 mph in a mile, with a top speed of 257 mph.

Not only was the UR matte-black twin-turbo Gallardo getting respect with a huge draw at the Mobil 1 booth, but according to Jesse Poole at Mobil 1′s PR agency Theory PR, the car was also nominated in the Gran Turismo awards, where the Best of Show car gets digitized and immortalized in an upcoming Gran Turismo video game.

Thanks to good friend of AutoGuide, Chris Grosser, we have quite a gallery of exotic cars from an ultra-exclusive event held in Florida.

Just over a week ago several dozen exotic car owners got together and rented out a two-mile-long aviation runway in Ochopee, FL, to see just how fast these cars could go… and just how big their owners’ cajones are.

Included in the long list of exotics was a twin-turbo 1000 hp+ Lamborghini Murcielago and several “Underground Racing”twin-turbo Gallardos. A stunning Saleen S7 also made an appearance.

“It’s not an everyday occurrence to view such cars in the wild,” says Grosser, “much less out on an endlessly long runway being pushed to their limits. It’s a thing of sheer beauty to view a car like the S7 being run to its full potential and not just sitting near a glass showcase or behind velvet ropes like a coveted piece of art.”

Amen to that!

Grosser, a student and photographer, obviously wasn’t out running his own hyper-car but did manager a 175mph ride in a friends Bentley Continental GT.

Grosser reports that many of the “tens of millions of cars” in attendance surpassed the 200mph mark, including those Lambos, the Saleen, and a Ford GT.
