Underground Racing Unveils the FIRST Twin Turbo Lamborghini Aventador LP700-4. This beast pushes 1200HP and reaches 60mph from 0 in just 2.2 seconds.

Underground Racing is proud to release the first Twin Turbo Lamborghini Aventador LP700-4. Our team was very eager to get started with an Aventador project since it was first released from Lamborghini. Once this Aventador made it to Underground, we quickly began to engineer the TT system and full build for this amazing platform. Countless hours of R&D and hard work went into this project. We spent a lot of time driving and studying the inner workings of the Aventador, and this platform is amazing, but it still seemed to be missing something- acceleration. The kind you can only get from a friend I call, BOOST!

No doubt the Aventador is much more advanced than the Murcielago and even the LP Gallardo. It seems that the factory really tried to make it hard for the aftermarket world to modify the Aventadors though. 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.

Now that the project is complete, I have to say this is truly one amazing car with the addition of the UR twin turbo build. We clocked the TT Aventador 0-60 mph time in 2.2 seconds on OEM street tires, normal air pressure and on a regular road. This Aventador drives just as it did in stock form, just a lot faster. The Aventador shifting is amazingly fast and we were also able to pick up a bit faster shift time with our Quickshift upgrade.

The Underground Racing TT LP700 system is a true work of art. Unfortunately, due to several attempts by other tuners to build knock off versions of our systems, only limited portions of information and images of the turbo system will be shown. As always, doing what only Underground Racing does with a Twin Turbo Lamborghini, we plan to see how far we can push the limits of the TT Aventador at several types of events with our demonstration TT Aventador. Stay tuned to UndergroundRacing.com for more videos of this beast. View Details ///
