I'm starting to think you are taking the cowl induction thing a little to far. There has got to be a reason why car manufactures don't use cowl induction any more. They always use an inlet at the front of the car to get the ram air effect. Corvette, Viper, SLR all use a ram air inlet at the front of the car. Its 2008 not 1968. The reason NASCAR still does it is because it is a rule not because its the most efficient means of sucking in air.

Paul, I can give you one reason why cowl induction isn't used today: packaging problems. Most fuel injection inlets on V8 or V10 cars are at the front of the motor pointing forward. It was be near impossible to reverse direction and space is tight as well. I have commented at length earlier about the Viper and Corvette in particular.
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.
