Tuners from Underground Racing does not have many specialties, but they’re very good at doing one thing and that’s turbocharging Lamborghini engines! They had a twin-turbo 1000+ hp Gallardo, and now it’s the turn of the Murcielago LP670-4 SV to get this treatment. So there you go, if 670 hp does not phase you enough, call Underground Racing and they make things right for you! Speed and performance aside, the modified engine also looks awesome. If I had this car I’d drive around with the hood open!
