I was also thinking that if there is an areodynamic gain then the engine will be producing less power to drive the car so less wasted heat anyway.
One way to test for drag is to use the 'coast down' method. drive at high speed on a flat road, knock the gearbox into nutural and time how long it takes to slow down.
Repeat in the other direction to average out wind factors.
This guy has reduced his drag from 0.34 to 0.19, but it looks a bit scary...

Don't forget there is always the lower grille as well, and that is in a very high pressure area so will take in lots of air and for the diesels takes in the intercooling air.
Where's mactech when you need him..?
