Although I was asking in general which is more important aerodynamically, sealing off the undercarriage, or redirecting more air around it by effectively lowering the front end with an air dam and possibly blocking the grille opening. It didn't have to be empirical data, just a rough estimate would suffice for the theory, as my current knowledge is more in tune with the powetrain side of things.
You might block the upper opening with cardboard and tape.The lower grille is at a higher pressure.See if anything shows at the pump.Watch your coolant temp. If you can make the inlet airtight,even better.
You'll notice,in late model cars,that getting air around,rather than under the car is preferable,so the airdam isn't a bad idea.
