Dont flame me!
A scoop kinda takes away the beautiful lines on the bonnett.
Why not something where it doesnt rise above height of bonnett, but still very effective?
Also what Mats mentioned would be a great idea!
Have a fast car without telling the world/police what it is you plan on doing when you hit the street, go performance x-rad before any cosmetic changes, cos if someone dishes you for your ride, you can leave them out of ear shot!!

Selling 1985 GTV6.
Ecu and injectors, lightened.....plays music.
i see only 1 option..not easy but the only viable option would be to take both left and right side and cut the center of the hood side off of them set both of them in place on the gtv hole and figure out how wide you want the louvers then cut both side on an even line and weld em together........take a LONG LONG time to cut, weld, file, grind, finish, prime, fill befor they were ready to paint...not an easy task but sounds like something id do for the fun of it 
or simply take both of em cut em down the middle and weld em back together leaveing you with 2 sets to work with one recessed louver opening and one protruding louver opening..either way ALOT of work...but fun type of work

That will probably look pretty good.
I measured temperatures on my grey supercharged car with and without the plastic hood piece installed. We drove it this way in normal traffic and running hard at Texas Motor Speedway in 100F heat.
When the car was moving there was no difference in either coolant temp or intake air temp. However there was a measurable in air intake temps after the car was parked for a short period of time.
For example when driving around off boost with an outside air temp of 80F the air temp in the plenum would be about 105F (remember on my supercharged car the air has to travel all the way around the engine bay and through the blower so it picks up some heat). It would stay down at 105F all the time as long as I stayed off boost. Now if I stopped and went into a store and came out an hour later, heat soak would cause everything in the engine bay to get hotter. This heat would be transfered into the intake and cause the intake air temp to be around 130F or more! It would take a few miles of driving to get it back down.
Removing the plastic piece, or I suspect using the louvers, greatly reduced this heat soak effect. So, while it didn't help at the track, it does help in the stoplight gran prix if the encounter happens after a shopping stop.
