Nice intake manifold... - The ITB thread
The firehawk hood's extractors have a lip in front of them that looks like it would create a low pressure area around the opening that would suck air out when the car is moving.

I found out that Sam is also doing his own ITB manifold now. Its a cast unit with lots of neat features. I don't have pics yet. But I hear its pretty slick.

This is my favorite thread. I just hate how I, personally, can't in any way justify the cost since I love every aspect of these intakes, and would love to have a reason to get a cowl hood for my Camaro.
30thta436, thanks for the updates, and for making them in this thread for those of us who are subsribed. Any pics of the whole car just for us to drool over?

I believe you when the car is setting still that radiator fan air is going to want to push air out.
When the car is moving is it lower pressure under the hood than "outside" and air wants to go "in" the vents. Or is it higher pressure under the hood than "outside" and air wants to go "out" of the vents.

You want a majority of filtered air that is available upon throttle. Again it all goes back to application. On a road race car you would want a good amount of filtered air available like on the Carbonfiber C5R airbox. This fitler solution would probably work best on a High RPM drag car.
An air box for an ITB setup needs to be big so that the airflow is smooth and plentiful. And the trumpet should stand higher than the base of the box so that the waves "Helmholtz resonance frequency" dont bounce off the lower part of the box and disturb the airflow.
As an example lets look at the M3 intake, its only a 3.2L motor but comes with ITB's from factory and revs up to 8k rpms.
Note how the trumpets are elevated from the base of the box.

Some updates. we have spent at least 20 hours on this intake. It is not a easy bolt on intake. I'm currently adjusting the linkage ( 
). Hopefully I will have some video of it at idle later tonight. After I'm done in a couple of days i will make a right up on some things that I had to overcome. But here is some more pics for now.

What was such a pain in the *** about it? What all required minor tweaking besides the throttle linkage? Was the main problem with your filtering system or something else?

The heat extractor hoods do work and they work great.
If there is a pressurized pocket at the base of the windsheild of the fourth gens it is overcome by the pressurized air flow out of the engine bay with a rear cowl exit design. The older F bodys had a pressurized pocket but also had mutch less rake to the windsheild. the introduction of the Super scoop on the 69 Camaro first made use of this but it was also a sealed envoronment. The breather was sealed to the hood and the hood was sealed to the cowl with a flapper valve that would open at full throttle. If the breather and flapper valve at the rear of the hood were removed the pressurized pocket was overcome by the release of the trapped air from the engine bay. I think the increased air flow through the radiator and/or intercooler along with lower engine operating temps is the bigger advantage. My Procharged SS saw a noticable drop in engine operating temp with the rear cowl screen and wipers removed, im sure the intake air temps also reflected the extra air flow.
