Underground Racing has released their 1500hp Lamborghini Gallardo Twin Turbo that has an amazing sound in the video when under full throttle. This beast was built for a client named Jonah, and it has to be one of the best tuning jobs performed in a while. Dubbed the TTG, it produces a mind blowing 1500 horsepower to the wheels. That is an incredible number, and when factoring a 25 percent drivetrain loss, it most likely shows numbers around 1875 hp to the crank! Boosted at 30 psi, the Lamborghini Gallardo runs on VP C16 racing fuel, which is a step up from the previous Underground Racing Lamborhini Murcielago LP640, which accomplished 1300 rear wheel horsepower.
