[2K05GT]

The 4th gen Camaro had a longer hood that helped to design a front air box that allowed for it to work. the 5th gen does not have that luxury.

Ram Air Myth...
Until the cfm flowing through the hood scoop is equal to or greater than the cfm that your engine is pumping, your HP increase will be exactly zero, zip, zilch. Say the vacuum pump that is your engine pulls 10,000cfm (just an example, but not an unreasonable number given the size of the engine) through the intake. You must be traveling fast enough to flow 10,000+1 cfm through the opening before you will see ANY HP increase. Now up to that point you will be increasing the volumetric effiency of the pump. The engine doesn't have to work as hard so your gas mileage and throttle response might improve, but that's it, no extra ponies because there is no extra air. You cannot defy the the laws of physics. How fast do you need to go to flow 10,000cfm through an opening area of 0.2sq.ft. (approx 6 inches in diameter)? Well at 1mph you will flow 17.6cfm, at 60mph just better than 1050cfm.....@ 568mph you will be just breaking even at 10,000cfm and then you start making real HP!!! Who needs a private jet when you have that car!!!! Keep in mind, this assumes that the intake is in an area of high pressure and will actually capture that much air. A typical hood scoop will not. It's a nice thought though.

Why the Z06 and Camaro scoops will not effect aerodynamics....
Look at the Picture of the Ferrari below, notice that the smoke stream is not touching the car, this in positive pressure, now notice the very front of the car, the smoke is farther away from the car here because the leading pressure is higher here and creates a "skin" of air so to speak. this skin or bubble of positive air does not move as fast as air further from the car.
for GM to put the slit up on the nose was a smart thing since it will not effect the overall dynamics. but it also makes the slit useless.
