Just days after Heffner Performance launched their package for the Lamborghini Gallardo Superleggera to an 8.72 second quarter mile at 169 mph, Underground Racing is answering back with a Superleggera package of their own. The difference? Underground Racing’s Gallardo has made Heffner Performance’s quarter mile record time a distant and short-lived memory. The Lamborghini Gallardo Superleggera by Underground Racing ran the quarter mile in 8.35 seconds at a speed of 181 mph.
The new Gallardo Superleggera package was specially developed for a customer who gave Underground Racing the following guidelines: "Do anything you want to it! As long as it drives like a street car and is the baddest Gallardo on the planet."
As a result of the not-so-strict guidelines, the Gallardo Superleggera by Underground Racing received a Stage 3 engine upgrade for its 5.2L V10 engine, "Quiet" Helix Billet 1st - 6th gear set and final drive gears, and a full "factory synchronized" transmission that uses all of the OEM E-Gear operating system. These additions gave way to a monstrous 1,750+ WHP (1,100 on pump gas), all while maintaining its street-legal status. The only other added feature is the new set of 18" wheels from HRE, but who really cares when you’re talking about a Gallardo Superleggera that produces that much giddy-up?
