Dallas Performance is one of the few aftermarket firms in the country that competently builds twin-turbocharger packages for Lamborghini Gallardos. The Texan outfit has unveiled one of its latest projects based on a Lamborghini Gallardo LP570-4 Superleggera. Designed from the ground up as a new system, the Stage 1 upgrade results in 800 horsepower on 93 gas, and 950 hp on race gas. Having swapped a twin-turbo Ferrari for this black beast, the new owner is clearly addicted to insane speeds.
