Underground Racing has made a name for themselves as the kings of
Lamborghini power, with several Gallardos that absolutely burn the roadways all the way from here to Russia. A day after witnessing a 1,500whp Gallardo hit 251mph at the Moscow Unlim track, the crew at UR have released a video showing their twin-turbo kit for the latest flagship in Lamborghini's lineup, the Aventador. The stock Lamborghini Aventador packs a powerful 700hp 6.5-liter V12 engine that can move it from rest to 60mph in 2.9 sec.
