Peter,
What you described above is the opening at the back of the hood of the Aston V8 Vantage. I use to have a full specs V8 Vantage Volante and the problem with the huge opening at the back of the hood is that it create a vortex inside the hood and the engine looses power (I drove the car without air box and it became very sluggish, probably lost 60hp or more) . Aston created a very large air filter above the 4 downdraft Webers with huge runners going down to the front of the car. On the UK POW version they installed a large spoiler and blocked off the front grill which improved both engine cooling and breathing. The point is, you want to increase the air coming from under the car, do it in small steps until you see improvements, also make sure that the aluminum cowling under the radiator is still there, mine was missing and we made a new one and I think it made a big improvement as well!
See the 2 big holes at the front of the inner fenders, this is where the huge air box connect to. Unfortunately, I could not find a picture with the airbox on.

Hi Emmanuel,
We have made the new bonnet, which can be seen in Classicus' Register, the change in profile is haedly discernable and as far as the aperture is concerned we put in the same number of holes (5) as the original but they are bigger. So there is not a single gaping hole, we believe that by trial and error we will get it right.
Cheers
