Good information. But have another look at that P-32 hood. The scoop is at the very front edge of it.
Isn't there a fair chanse that it will chatch the air stream before it leaves the hood surface?

But I admit this is details. And have you ever tried to raise your hand up thru an open sun roof while driving at highway speed? The wind hits your hand right over the roof surface, not like 14" higher up.
