I personally fail to see how this is going to make the car faster. maybe I am
missing something? How do you propose to change the size of the opening
dynamically, not the actuator method but the inlet size itself mechanically? How
do you do this with out the same loss in aero? it must be a very convoluted
structure i would think to have a decreasing opening with an associated change
in
overall area. If you use anything like a flat plate or butterfly won't you still
have all the aero drag associated with the overall size of the structure? If
this
is only to keep the inlet pressure constant wouldn't it just be easier to place
it in a spot that does not have any ram air in the first place?
