One more thing about ram air. If I had a turbo would It be any help to get a cf ram air hood from dg or should I just get the cf hood. I don't what to know which is a better value, I just want to know if the ram air hood would make the car perform better than the non- ram air hood.
You have two goals with air. You want cool air, and more air. the ram air hood you see is going to direct air into the space behind that hole in the pic. A turbo doesnt rely on "natural" airflow into the engine compartment. That is what a turbo does, force more air into the chambers (the turbine's job).
The advantage to a ram air hood like that with a turbo is that in most turbos the intake filter is right behind where that hole is, meaing the turbo can draw cooler air from outside than it would get from the warm engine compartment.
As far as wanting cooler air, there is a thread on here with a very good explanation, search for it.
In response to the second mail, part of a turbo kit is the intake. Look at some pics of turbos and you'll see the turbine in front of the block (on the left in our cars) and a filter extending to the right (behind where that ram air hole is). I suppose one could fabricate a CAI that goes down behind the bumper (and thus lower) for a few degrees difference, but cooler air can be achieved in other ways, through better head gaskets, intercoolers, and of course a well-cooled turbo (as you mentioned).
Good questions.
