Great finds can be found inside and outside of the expansive SEMA show at the Las Vegas Convention Center. Today we found the "Obsidian," a 900-horsepower beast built by Matt Couper of CoupeR Design / Autoworks International. The twin-supercharged, 900-horsepower 392-cubic-inch V-8 breathes via a very mean-looking (and mean-acting) hood scoop. The design modifications on the car are extensive, as well. Over eighteen unique mods were made to the body.
