Underground Racing have done it again. They have managed to fit a twin turbo to the Lamborghini Aventador bearing in mind the car was already brutal with 700hp and a sub 3 seconds 0 to 100km/h. The upgrades take it to a mind-boggling 1200hp. A 0 to 100km/h prediction of 2.2 seconds will not be far off the mark and this will be sure to hurt your insides. Watch the video below and watch till the end to see just how savage this acceleration is… I wonder what Heffner Performance have got up their sleeves now?
