    Am I the only one that thinks it looks awesome except for the (even though it's functional) roof/rear-windshield scoop for the engine??

    It isn't functional in the way a roof scoop should be used.

    I know it's not connected to the engine on this car but what do you mean?

    I finally found a pic of what i have been on about!



    F1 Technical: Cooling

    Just above the driver's head there is an air inlet that supplies the engine with air. It is commonly thought that the purpose of this is to 'ram' air into the engine like a supercharger, but the airbox does the opposite. Between the airbox and the engine there is a carbon-fibre duct (1) that gradually widens out as it approaches the engine. As the volume increases, it makes the air flow slow down. The shape of this must be carefullly designed to both fill all cylinders equally and not harm the exterior aerodynaimcs of the engine cover, this all to optimize the volumetric efficiency.

    The following picture displays the uncovered rear part of the championship winning Renault R25. The element marked with (1) is the airbox that guides air into the engine (2) to be mixed with fuel in the cylinders. If is therefore not an aid for cooling but simply a requirement for the engine to function.

    I still don't get what you mean? lol. I've always known that. But what's that apply to the NSX?

    I guess that fact that it doesn't have a direct way of feeding the intakes. Yes, that whole gets air in and out of the engine compartment but it could have been made to work more efficiently.

    OHHHHHHHHHHHHH LOL, I was calling it nonfunctional all along because I didn't see a direct feed straight to the engine like it should be (pic you posted of the F1 car) I never even considered it's just throwing air into the engine bay That's why I was calling it nonfunctional. We are on the same page. Now I get what you have been saying.
