If the name Underground Racing rings a bell it's because we've reported on some of their insane Lamborghini creations before. You might remember the Gallardo that could knock out 10 second quarter mile runs, or the Superleggera that topped 250 mph at the Texas Mile earlier this year.
The company has now turned to tweaking the V12 in the Murcielago, specifically the mighty LP670-4 SuperVeloce. Underground's twin-turbo performance package for Lambo's flagship starts at a whopping $129,000 and boosts the 6.7-liter V12 to 1,100 horsepower at the wheels on pump gas. You can get an additional 200 horsepower if you decide to use race fuel.
To show off its latest creation, Underground Racing created a teaser video of the twin-turbo Lambo, complete with a few acceleration runs and a rear view of the massive, singular exhaust pipe spitting flames during downshifts. Have a look for yourself after the jump.
