[DeTomaso] Ram-air Scoop

I wanted the scoop to be as small as possible and not look obtrusive. I 
wanted it to follow the roof line and look "right".
I used the calculation of a carb opening (5.125" D) to calculate the 
required opening which is 20.57 "sq. My opening is 24.45"sq. So I'm hoping 
there's no restriction.
Air speed at opening? Not a clue.
Dan Jones said rule of thumb is 1% gain in torque for every 10* lower air 
inlet temp. Goram recorded substantially lower temps at 50+mph. Not much of 
a difference at lower speeds.

As long as the scoop is sealed to the air box you should achieve the desired
result. How does the inlet opening area compare to the inlet area of the
throttle bodies? Perhaps more interesting, what air speed do you get through
the opening at max rpm and 100% VE.

I don't think it will. I should've called it a Cold-air scoop. That;s really
what I'm after. There is a new Ferrari(?) that has a new ramair inlet and
apparently, it gets an extra 7hp at 150mph+.
My laptop was reading 180* air intake temps on a 75* day. I'm hoping this
brings the temp down which should help performance a tad.

Great concept molding it into a sugar scoop spoiler, but I wonder if it's
going to have enough rise to get out of the boundary layer over the top of
the car.
