Hmmm as we all know Alum disapates heat 5 times faster than steel and CF isn't good at diapating heat and the weight savings isn't all that great , so it has to be more for looks than practcallity .
Also you have to remember I'm gonna be 50 soon so its less about looks for me and more about good handleing and drive ablitiy .
Hi Boily
The heat dissipation from the surface of the hood is minimal.
The radiator is responsible for keeping the temperatures in the engine in normal levels.
Now the radiator and the Inter-cooler that many people with FI are using are working more effective when air is flowing from them.
If you see the front of the car there is a big opening for the radiator, which means that a lot of air is getting in but that doesn't mean that the air is flowing!
In order to have the best flow you have to provide also a way for the air to escape from there!
That what this hood is doing, is providing the most effective path for the air to escape from the engine bay which normally is just leaving from the area under the engine.
Some other interesting things:
-> By opening the headlights - or doing the sleepy eye modification - you give more fresh air to the intake by at the same time you are lowering the efficiency of the radiator because you increase the pressure in the engine bay and as a result smaller amount of air is flowing through the radiator.
-> If you see behind my NACA duct (in the headlight lid) there is an isolator box which ensures that (a) the intake sucks only cool air from outside (b) and that the pressure in the engine bay stays low.
-> The popular JDM style mod which lifts the rear end of the hood actually works in the opposite way than most of the people think.
Instead of allowing the air to escape from the top of the hood it sucks air from there and it make the airflow through the radiator really bad!
This hood is probably the best available design because it has the opening in the area of the hood with the low pressure and over the back of the radiator!
