The most insane tuners of them all from Underground Racing has came up with another twin-turbo 1000+ hp Lamborghini. This Gallardo Superleggera is made for Richard Holt and in this video you can see him going past 250 mph mark in Texas Mile high speed event. It’s not the first time that Underground Racing does this, they’ve made 1000-hp Lambos before and they also have a similar package for Audi R8 v10, but here’s the proof that their cars actually work!
