The vanity panel would have to endure pressure from air flowing at it of over 300km per hour. Still think the engineer is pretty confident, given that it would have to be designed for this, that its strong enough to be pushed on the nose tip..poz wrote:I suppose that this image close any speculation on Ferrari nose tip. If it were made by the "vanity panel" i suppose they will not use it to push the car...

If the throat is the "kink" line where the flat botom ends and thre diffuser begins the higher the mass through there, the lower the pressure the higher the downforce from the underbody.
If the expansion is constant more mass flow could be achived at the price of less expansion. Depending on how the relation between mass flow and expansion ratio is you could have a net loss or gain.
Assuming that the overall expansion size is limited by diffuser regulation more mass flow under the ffloor will only be good if you can achieve more airflow over the floor as well, improving expansion ratio.
Therefore you want more air under the car but you will want to use most of it over the diffuser and only a small fraction under it to increase mass flow.
Not a cut out.
