Underground Racing has bolted twin turbos on Lamborghini's already ballistic Aventador LP700-4 to send it rocketing from 0-60 in just 2.2 seconds.

Underground Racing has ripped the covers off its custom tuned 2012 Lamborghini Aventador LP700-4 Twin Turbo. The highly modded version of Lamborghini's fastest ever production scorches from 0-60 in an F1-quick 2.2 seconds.

The North Carolina-based tuning house has bolted on two turbochargers to the Italian icon's already ballistic supercar and in doing so, launches it into the stratosphere as one of the few cars producing in excess of 1000hp. In standard trim, the $379k Aventador accelerates from 0-60 in just 2.9 seconds, with the performance enhancements cutting another 7 tenths off its sprint time.

It pulls off its remarkable acceleration time shod in OEM street tires, normal air pressure and on a regular road. However, it does require a full engine rebuild of Lamborghini's 12-cyclinder masterpiece. Aside from the engine rework, Underground Racing also fitted a custom Quickshift upgrade to take full advantage of the additional horses on offer.

"It seems that the factory really tried to make it hard for the aftermarket world to modify the Aventadors though," reads a statement from the company. "However, the Underground Racing team moved quickly through the road blocks that exist. For now, the UR TT Aventadors will only be released with FULL engine builds. Through our research, we have found certain conditions that make this a requirement."

At the time of writing, Underground Racing has yet to publish the full specifications or exact pricing of the upgrade. Underground Racing performance upgrades of this nature typically cost around $100k for parts and labor. Worth it, if you've got the cash we think.
