Underground Racing has one of the most illustrious track records when it comes to twin-turbocharging Lamborghini’s and it’s little wonder why. In top tune, they can extract upwards of 2,000 horsepower from the Gallardo’s 5.0/5.2-liter V10 engine. As a result, their cars are some of the fastest in the world as demonstrated by the videos above and after the jump.
Less than a week ago, we brought you a video of Robert Himler’s twin-turbo Gallardo running on race gas for the very first time, and that showed the incredible acceleration which these TTG’s are capable of achieving, with his particular unit being geared for acceleration rather than top speed.
However, that’s not the route a 1,500AWHP TTG went in a run at the recent Unlim 500+ event where top speed was the aim of the day. Running up the perfectly straight road which stretches for in excess of one mile, this incredible Gallardo Nera managed to top out at 251mph just past the 1 mile mark. It also hit 240.84 mph just a few seconds earlier and completed the one mile run in just 23.861 seconds.
Thankfully, the whole run was captured in an array of impressive camera shots and we have both of these videos which really show just how impressive this car is. In the second video at the 55 second mark, you’ll see the driver kicking the car into 6th gear before the 251mph run was reached just 5 seconds later, suggesting that this car could go even further if its aerodynamics were improved further, there was more road to continue, and if the driver was brave enough to keep pushing it.
Nevertheless, this is a truly incredible achievement so check out the videos!
