Since Ben brought up that the pic existed in the hood thread, I had to find it. Granted it is for a NB and there is no designation about what speed it was tested at, it at least gives us some insight into airflow. I figured that I'd post it here for reference.

Actually, I should have been more clear in my description. The diagram shows air velocity not pressure. So red would be higher velocity airflow and green/blue lower velocity airflow. Which is why in theory placing a vent toward the front of the hood "should" be a good location for an extraction vent as typically higher velocity should mean lower pressure and why the back of the hood "should" be a good location for a cowl intake as it is a low velocity/higher pressure area. As another example, note the nice low flow/pressure area right where a windblocker usually makes a difference. BUT, again, this can change based on airspeed and the pic did not have any indication of airspeed.

Go the m.net and look in the dyno section for the 28rs dyno on a 1.8. The guys 2nd post has a pic of his red car with them. They are one of the only oem side skirts made for the NA. I don't think they were ever released in the US though, and have been discontinued for a while. Only good looking skirts IMO.

Sorry no hardtop version and no legend. I am sure that the colors indicate airspeed and not pressure as the original file was named wind velocity or something of that sort. No other versions. It was a file that RodH found on some site in the UK with no other leads.
