Momma said not to gloat, but for the lucky SOBs that own LS3-powered Camaros, it's awfully tough to stay modest. With 376 cubic inches, 426 horsepower, and rectangler-port heads that flow an unbelievable 330 cfm from the factory, it's essentially a baby LS7. Considering the astounding naturally aspirated horsepower potential of the LS3, the prospect of bolting on a power-adder may seem rather peculiar.

Nevertheless, not everyone cares for a lumpity-lump idle, spinning the stock short-block to 7,500 rpm, and beating on the rod bolts like they owe you money. Turbo and supercharger kits offer an appealing solution, but cost as much as a used LS1 fourth-gen, and take way too long to remove when it's time to head to the dealer for warranty work. (Not that we'd endorse that sort of thing.) As such, good ol' nitrous injection systems are, and always will be, the best bang-for-the-buck horsepower mod in existence, and Nitrous Outlet has developed what could very well be the perfect way to juice an LS3 or L99 Camaro.
