I disagree with your assessment that it is not the most efficient means of drawing air in. Quite the contrary. Anytime you have a duct at the front of a racecar, it will create additional drag. Also, any debris on the track will be sucked up into the intake. With cowl induction, you get air coming at a high velocity w/o any drag issues or sucking any debris into the motor.
I am not sure where you get that 180 degree bend. Look at the picture: The air inlet is on the side of the box. How hard would it be to just make the tubing go backwards rather than downwards?
If the cowl area wasn't a good area for air induction, all the car manufacturers would not be using as the source for ventilation in their cars. They would be pulling it from the fenderwell or front of the car if it was that much superior.

Well said.
The tube that comes out of the side of box at the top goes to the TB. The tube at the bottom points toward the front of the car. This is the tube you need to run to the cowl. If you want that tube to go to the cowl, it needs a 180 degree bend.
