If you are into tuned Lamborghinis, then you have heard the name Underground Racing before. The Charlotte, North Carolina, based tuning firm has created some of the most insane and powerful Lamborghini models to date.
It’s latest project is the first ever twin-turbocharged version of the new Lamborghini Aventador LP700-4.
In factory tune, the Raging Bull’s 6.5-liter V12 engine delivers 691hp (700PS) for a top speed of 350 km/h (218mph) and a 0-100 km/h (62mph) acceleration time of 2.9 sec.
After the engineers at Underground Racing get their way with the 12-cylinder unit, the twin-turbocharged engine pushes out more than 1,200-horsepower and reaches 60mph (96km/h) from standstill in 2.2 seconds.
That’s all the data we have for now, but Underground Racing has released a three-minute long video of the Lamborghini Aventador TT that you can watch after the break.
