That is similar in design to rear engine turbo’d cars that have intercoolers. Rear Side entrances. Some of them claim they use it to cool the rear brakes (They provide less braking power and less cooling is needed so I don’t see why they would make this claim) but most that have intercoolers say it is to cool the intercoolers. Intercoolers are placed vertically in the direction of the car and the outside scoops are used to catch the moving air while it is forced through the intercooler.  
But those cars also have auxilary fans behind the radiator/intercooler for whenever the car is not moving.  
Your design is good at the front, but you need a fan for when the car is not moving. And you need a lot of engine space. I can see it on something like a mazda rotary engine or even something like a Buick Grand National/GNX.  
Now that I think about it, I remember seeing a gold surpa in a magazine once. It had an RB engine in there and somehow they managed to mount the radiator horizontally with a scoop on the hood so the air is forced through it.  
Sento Jidosha didn’t you have the same idea somewhere?

I know you hate the idea Sento Jidosha, but it is an extremely easy way to produce extra power, have better weight transfer and keep underhood temperatures down.  
For my Datsun before SDS became big with it, I was planning on doing the same thing. The Buick GNX I believe actually has an external oil pump that can be used for running oil to the back where the turbos will be on either side. At the back of the Datsun, I made the widebody with two big holes. I was planning on putting the intercoolers there and forcing air through them.  
Right now though, all I have for the two big holes are a set of little spoilers behind the flare and it also “Cools the rear brakes” :R
