Whats the point of a COWL HOOD?
I see them on all sorts of drag street cars, and even a few trucks... Do they do anything or are they just there for looks or what?
-Thanks

if you are running an induction system that sits too high to fit under the stock hood, you can gain a lot of clearance with a cowl hood, and they are made to draw air from a low pressure area that is created at the bottom of the windshield on cars. ive got one on my car and you can see it work, spray down the hood and winedshield and go for a spin, the droplets on the lower 12" or so on the windsheild will run towards the center of the car and then travel down the windshield towards the cowl opening, kinda neat

Normally you dont... My one friend had a 91 RS and had a 4 inch cowl hood and an open element and he drove that in the rain all the time. i cant imagine how it worked but it did...
and Z2Eight....do you have anymore pictures of your car?? Where are you near pittsburgh?...I live in Allentown but i go 2 Pitt so basically im in pittsburgh 7-8 months a year now...

i dont drive it in the rain on purpose... but the rain isnt going to be blowing straight into the engine anymore that it would be blowing up into the engine bay with a closed hood, the aircleaner may get damp, but i dont know if the engine would actually suck water

Got mine for weight savings, they dont make stock iroc style hoods, so i went with the lowest cowl possible. looks good too.

Rain really isn't a problem as stated above.A screen can be fabricated to keep out leaves and other pests but not obstruct airflow in.And the other added benefit is letting hot underhood air out.

There's 2 main points to a cowl hood..
1) so the engine can draw in cooler outside air from the base of the windsheild
2) to have room to fit your intake/carb/air cleaner setup under the hood

Jongblowed hoods are just a rounded off cowl. Yes they are lightweight because theyre fiberglass. I would say the diff between a fiberglass Jong' and a regular fiberglass cowl is negligible. But the Jong is just plain nasty.

So... maybe Im a little partial.

The hood lifts up and then swivels up just like the stock one. Hard to explain, but it should open just fine. Unless you broke something...

For the Trans Am's with the "Power Bulge" it's on a solonoid relay. I don't know when it opens, but I have a special air cleaner assembly set up thats specifically designed for it. It's supposed to take the air from the bottom of the windshield and pull it into my carb (84 T/A). I think it's supposed to give the same effect as the dual snorkle on the Camaro's...but instead of pulling twice from behind the headlights, I only pull once from the headlights and once from the cowl. Tomorrow after work I'll take some pictures and see if I can get them posted for you.
