Now that 1,000 hp is the new 500 hp, a 900 hp Mustang Fastback may not carry overwhelming numerical firepower. But the Obsidian SG-1's allure is in the execution. Sporting a novel intake system for its dual superchargers and twin intercoolers, the Coupe-R merges old muscle with new tech, for a result that doesn't seem retrograde or neutered-modern. More than 10,000 hours of work by CoupeR Design and Autoworks International went into the build, which included major engine, transmission, cosmetics and electronics mods. [Gallery]
