Nope, the scoops he put there are designed for the top or side surfaces.
These submerged ducts are called NACA ducts. They were invented by NACA, the agency that later became NASA as a high pressure and low drag scoop. The NACA ducts are located in the belly pan right before the rear diffuser and they take in air to keep the lower part of the engine compartment, where the exhaust system is cool even though it is completely covered by the lower diffuser. This keeps things in the engine compartment from getting hot and cooking off.
A little more on the design. http://revlimiter.net/mods/duct.php
