Today we preview one of the fastest Lamborghini Murcielago LP640’s tuned by Underground Racing. They’re an emerging car tuning company from America that customizes Vipers, Lambos, and the Ford GT.  From the pictures that were released, via the LamboPower forum, we can see the car is twin-turbocharged with a bespoke exhaust system.  They haven’t released the numbers or specifications yet; however, the last Lamborghini Gallardo Underground Racing tuned generated 1300 rwhp.  That is an insane amount of power and we can only expect them to increase the numbers for this Lamborghini Murcielago LP640.

We are all wondering how they can produce 1300 rwhp by only turbocharging this Murcielago, but then again, it is a Lamborghini.
