Granatelli Motorsports was at the event showing of their bolt-on twin-turbo kit designed specifically for the LS3 and L99 Camaros. The turbos can support up to 1,300 hp, but even at only 7 pounds of boost, they can put well over 500 hp to the wheels. We were impressed at how neatly it all fit under the hood.
