Vented valance/header panel
Ok guys,
here is what I have come up with. Everyone keeps wanting the copy of that famous pic. of that silver widebody with the holes cust in the valance. Well, here is my version of a valance. I think this will tie in real well with the one duct in the right side headlight and the "vent" in the hood. This will draw the air in and cool the radiator, oilcooler, or intercooler. I have done some testing will an air pressure meter in this location and it shows to have a high pressure right in this location. I believe this will be a very usefull air duct!! Anyway here is the begining of the "plug".

Anyone who owns a Toyota truck is also a good friend of Bondo, and vice-versa...
or should I say "Body Filler" to make all the brand-name freaks out there happy?
I really like the look of the Valance panel though... I wish I had money

A general rule of thumb for measuring Air pressure in a region is, the Moving air over an are has LOWER air pressure than air that is Stationary in relation to the surface.
to find the low and high pressure areas on you 7 theeasy way is to go for long drive on freeways and highways in the RAIN! you will get the lines on your car where trhe water moves, eg, line going over the roof, air is moving here and hance has a LOWER pressure,
if you look closer at the bonnet (hood area) after a good drive in the rain, you will see the water patterns on the front valance show that it doesnt move much at all, yet thurther up the hood, usually past the rear of the headlight cover, you will see where the airflow increase speed over the hood, hence lowering air pressure.
If you notice some salon style race cars have what looks like a airbrake for a rear spoiler/wing, the theory here is that the spoiler will catch the air and slow it down to a speed slower than the air passing under the car, hence creating downforce by virtue of Higher air pressure above the car than under it.
If the air flowing Under the valence and into the radiator is faster than the air above the valence, then putting an intake there will work well, as the higher air pressure Above the panel will force it into the intake to the lower air pressure area below it and into the raditor area

how tall is that opening? it looks like 1.5-2 inches... looks good though, I had plans of doing the same thing but they are changing as is the over all shape with the 944 front bumper.
Bery nice work though

Just a suggestion (don't know if you thought about it):
You should put a vertical support peice in the opening to keep the flex on the peice down (if needed) and that way the fiberglass/paint won't crack under pressure.

That's awesome, I like it alot. I'm keeping my eyes on this one. Now if I could only find the cash to get this and a vented hood at the same time, Mmmmm.

doh!!! another thing i have to buy before i get paint
hehe nice job
FG headlight covers
FG or CF hood
FG vented valance
thats what i plan to buy b4 xmas
heres a though you should add up all the weight saved with all your great pieces.... i bet with a cleaned up engine bay and other mild weight reductions itd prolly be close to 100 lbs ?!?!?!?! a whole tenth of a second in the 1/4mile.. for you draggers and prolly some better times for you autocrossers

Oh yah, there will be some alum. brakets that are glassed into the part and will attach at the factory location. The part already has the same mounting as the factory piece under the hood area.
