There's no need.
Don't do it Len.
Unless you've got a low profile blower, trade your car in for a a 70's vette or truck, fiberglassed like the idiots cigarette filters that figured it was so cool. Reminds me of the hump on the intelligent dude from Notre-Dame, AND I'm not talking about the University.
The bells, the bells!
That hood, that hood.

he will have something better than a low profile blower....he will have the itb set up with simard cams and 600 plus NA hp at the wheels
the hood mod is discrete and well in keeping withthe overall build of the car!!!

I can't remember who it was, (Tony Lapine maybe?) but someone once said that the 928 was designed like "a used bar of soap". Softened edges, nothing "sharp" on the car.
I like that wide, used bar of soap look for the hood scoop!

If Ferrari can make a functional hood scoop fit in to their design, I believe we can do the same with cowl induction.
It seems our cars have very few hard crease lines, especially the S4/GT/GTS cars, so any hard creases may look out of place.
Also, not-so-subtle design differences between the S cars vs. S4/GT vs. GTS cars, very likely have an impact.
I have informally struggled with design ever since I was a kid drawing cars with monsters (ala Ed Roth), and I admire the efforts of you guys that consider, or actually do, modify our cars - it is not easy IMHO!

That is an awesome 550 Ferrari car/hood. I built a hood just like that for a customer years ago. I think it would look great on the 928 but probably wouldn't work for Serlings application with the onslaught of Engine mods. Might be able to pull off the 550 hood with a stock motor. The computer renderings are close to what the hood will look like when its completed. The side profile is 100% correct to the computer rendering. Everyone has there own ideas for there own cars, but in the end, the one paying the bill gets what they want. Looking forward to the pictures of it completed....
All you guys have some GREAT cars !

looks nice, but hardly functional. they have a trade mark hood scoop from the maranello 550, but is purely for looks. again, this area, even on a ferrari is a low pressure zone. go look at the race car maranello and see what occupies this area of the hood. (vent, not scoop! 
)
sorry to rain on the parade, but the vent is for air intake, but its not a functional ram scoop. its in a area of low pressure, THATs why they have the air cooling and downforce vents, a the exact same spot next to it. Its for looks. its the maranello trademark look.

Thank you for clarifying, Mark.
Disappointing that Ferrari includes something so functional-looking, just for looks, as part of that design. Makes them more like so many others.
My point was that a scoop can be made to look good on an exotic. I will still cling to my belief that a *functional* scoop or cowl can still look "right" on an exotic. If Sterling's cowl turns out as he hopes, I believe it will accomplish this!

There really is no such thing as ram air. Engines ingest massive amounts of air. For a scoop to generate positive pressure into the intake, it would have to have several square feet of surface area.
I saw an internal document once referencing a Ram Air hood. It was only for perceived customer benefit.

Of course the Ferrari scoop generates a high-pressure "ram" air intake.
That part of the hood may be a low pressure zone absent the massive scoop when measured normal to the flow, but immediately when you put the directed scoop facing the flow there you get a above average pressure at speed. The direction in which the opening points is so important for the kinetic pressure. That's why the rearward-pointing openings see below-average pressure and forward-pointing openings see above-average pressure.
Every internet engineer should know this after years of education by google.

Except..it doesnt have to be POSITIVE pressure.
Just less negative pressure..the goal is lowering the pressure differential into the system.

Was about to question that as well..
The front facing scoop is not a scavenge like the other photos clearly demonstrate.

True or not, Ferrari did claim the scoop on the 550 added X hp @ Y mph.
I've also read the scoop allowed a lower hood profile.
If anything it's a damn good cold air intake.
