Hey Exhaust Depot ("E.D." for short cause I'm sure your going to be referred to alot), could you do me a favor and see how well this ram air system works.... I was thinking if you could get an air compressor and stick it in the scope, and feel how fast the air is coming out of the ports relative to the air going in. I'm sure it must be functional to a good extent; they were very weight concious, and that hood looks heavy (correct me if i'm wrong).
The design over the intake is smart too, circulating fresh air pretty well around that channel over the intake. I would say if you do add in a cone, i would recommend cutting a whole the size of the cone in the channel, and actually have the cone mounted far up enough to stick in the whole. All the air going through there would be used in the intake only. That, in my opinion, would be an ideal cool air system for this car. Any other effecient ideas, those them around!
Kinda long winded, but hopefully it'll get some ideas cirulating around, plus I had to add my $0.02!
