One question I have:
Why is the nose ducted on the sides like the FI/Sauber? If you compare the length of the 'tip' to that of the RBR, they are pretty much the same. What benefit is there to create the nostrils rather than just have then open? Where are they ducting the air?
EDIT: To clarify, FI are doing the nostrils to get the holes further up the sides of the nose than the otherwise could. McLaren aren't doing this. The are also not using them to channel the air in behind the nose, because they don't appear to exit above the cape. So what does this allow them to do that a RBR tip doesn't?
I believe it is down to widening the gap between the pylons in order to maximise flow to the cape.
Moving the wing pylons wider increases the surface area of the nose. This creates space above the minimum regulated requirement at the nose tip, so it is better to reduce the impact by adding ducts. Although not as good as free flow air, the overall volume should be increased.
