 That would be NACA.
http://www.up22.com/Aerodynamics.htm#NacaDucts
"NACA stands for "National Advisory Committee for Aeronautics" and is one of the predecessors of NASA. In the early days of aviation, NACA would mathematically define airfoils - e.g., NACA 071 - and publish them in large reference texts, from which aircraft manufacturers would select for their specific applications. As you probably know, an airfoil is a compromise of lift versus drag, and this relationship changes with the airflow velocity, density, etc, so no one airfoil is optimal for all conditions. As to the NACA duct, I'm trying to say this without sounding professional, but here it is in case you're interested.
The purpose of the duct is to increase the flowrate of air through it while disturbing the aerodynamic boundary layer around the fairing as little as possible. When you increase the cross-sectional flow area of the duct, you decrease the static pressure and make the duct into a sort of vacuum cleaner, but without the drag effects of a plain scoop. The reason why the duct is very narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area, but not so quickly that the airflow separates and causes turbulence (and drag)."

ducattiman, don't be shy. Tell us how you really feel... Vortec Fiero was technically correct, but then again, so what? First off, I'd like to see his posting skills in Dutch, secondly, the vents look cool, and that's really all that it's about. Fie Ro, thanks for posting your accomplishments. It definately makes me itchy to get another Fiero when I get back to California.

This is the only picture of the finished hood I have around for now: 
There is no cutting of the front trunk required. I have the sunroof and I still like to be able to store it up front. About the NACA ducts: They may be used in an other way. BUT I have tested this configuration in my windtunnel and it shows 10HP extra at the rear wheels! 
that's enough for me! GTR windows. I still have to order a set (from Doug/Fierowarehouse?) but I have designed my own GTR logo so I will look for a set without logo....
If someone has a nice set of new GT windows without logo for sale I might be interested! Minngreen: thats a nice solution you have for your skirts! I hadn't thought of that. real clean. For now I keep mine this way but IF I am going to change it I know now how to do it! Thanks The M3 skirts were fiberglass. They cost 205 euro (arout $200) which is quite normal for sideskirts.

I bought them at the 20th, but I'm not sure if they're going to go with the car or not yet... They're reproductions, and have the "GT" logo, but it says "GTR" with the R in the usual red writing. I may sell them at some point, I need to get the car in one piece to see what they'll look like!
