Camaro Hood Vent idea [Archive]

Thought I would post these illustrations to get some feedback from everyone. We are designing some vents to fit onto 1st gen Camaro hoods. They are designed to work with stock steel hoods, our carbon fiber hoods or fiberglass hoods. You would need to cut holes in your hood to retro fit them in place, but would be functional to let air out. They would especially be good for twin turbo set ups. The would be available in carbon fiber or fiberglass and will conform to the curve of the top surface of the hood. They would screw in from the under side. We are working on some for the second gen too. I think that any of the vents we are working on would work for a variety of cars actually. At least that's my goal.

A little big, but I like them. I was thinking about using Lumina Z34 ones on the cowl hood I have for the Monte.

I like the looks of those! I have been thinking of making my 91-92 Z28 speed blisters functional. I would like to see what the bottom side looks like.

Excellent idea another would be to do vents that fit in the ice tray hoods.

I will be using this for some renderings though thanks!!!

I'm assuming you mean the SS hoods with the fake metal vents? Those don't seem to be in a strategic place to vent air out and probably wouldn't work too well as an intake unless it was a big scoop. It would be nice to have a more updated touch there, though, you're right.

Yo Z, I think I sent you about a dozen shots of some vents that may be useful. Wasn't sure if you remembered that or not.
I still want to do something on my car as well....

Or just put louvers in the hood like Stielow did with El Mule.

"Wheel to Wheel built that from an NOS GM cowl hood. They removed the inner structure and did the louvers over the turbos going into the engine compartment instead of sticking out. They also had to add bracing and move the hood latches to the corners. It's an awesome piece."

Its kinda ironic when I talked to you a couple of weeks ago about doing a one off piece with some louvres and now all of a sudden your showing a product for market (you didnt mention that via phone) A little different than what I imagined but its a great idea as making them as inserts instead of production hoods for the individuals that already have CF

I have a customer in the Philippines of all places that just kept on me about making a hood with vents. He finally gave me a good deposit to get started. I didn't want to do a one off hood just for him, so I came up with this idea which I originally had for the 2nd gen. I did a foam mock up of a vent for a 2nd gen about 8 months ago and also did a computer model and a rapid prototype 3-D print. I figured if I created a vent that most people liked, I would make it as a retro fit for any hood. The trick will be to make a template to cut the holes (probably a router would come in handy here).

I like the idea of vents and would buy them from you if the design was a bit less 'heavy'. I'd REALLY like something like the ones on the Mule above. Possible?

I like the style of the vents, but would prefer them as low-profile as possible. Make them sit "into" the hood, instead of on top of it.

Steeda has a cool cowl hood for the 5.0 Mustangs that has vents like these... albiet a little longer and more slender... worked great on my supercharged 93 Cobra!

Matt, I like the vents and it would sure be nice to pull hot air out from under the hood. hmmm... I wonder how that hood with the vents would look on Penny (painted)?

Keep in mind that I don't think Matt wants to design a whole new hood but rather something that can be retrofitted to existing hoods.

Also keep in mind that for them to be effective there needs to be some protrustion above the hood to enhance the low pressure and thus more efficiently draw air from under the hood.

The ones on the mule work because they are really close to the front of the hood which is relatively low, but they'd work better with a raised bit on their leading edge.

Its funny, just last weekend I was looking under the hood of my Vue, trying to come up with an idea on how to get more air in there to the filter, which I have located right behind the passenger side headlight. These look good, and so do the ones posted by Samckitt, but they're all for getting air out. I'll figure something out.

Great looking vents!

Not to hijack the thread, but I have always wanted to put these fender vents on the Monte.

https://static1.pt-content.com/images/pt/2008/07/499d_1JPG-1.jpg

But unfortunately the Monte fenders are not big enough to do it. I would have to have them made at about 70% of original size to work.

These look like late 2nd gen fender extractors. Damn true is right, they could work on the right shaped hood. They look similar to the 2nd gen hood vents we made a prototype of. I'll post a picture of it.

Here are some pics of the 2nd gen scoop. I just placed it on top of our cf hood prototype to give an idea of what it would look like. Try to imagine that it is cut into the hood so it lays flush. It could also be placed more forward on a flat hood or anywhere it makes sense. It is designed specifically for the 2nd gen Camaro hood with the same angles. That's not to say it wouldn't work for, say, a Chevelle or Mustang or something. We would plaec some aluminum screen material in the hole to dress it up and keep the flotsom and jetsom out.

MaTT, are those pieces you have made? Compared to the fender vents I pictured above, are they smaller, same...?

If the heat comes out of the engine compartment via vents in the top of the hood , will the heat get pushed into the interior of the car via the intakes located at the base of the windshield ?
Like , maybe would it be better to evacuate the hot air from under the hood some other way ?
Or does it matter ?

The main reason I'm developing these vents is for customers with a twin turbo set up since they develop a lot of heat. Since hot air rises, having the vents directly above the source of the heat would work well (especially when stuck in traffic). Secondarily, they will also evacuate built up air from under the hood coming in through the front grille. This build up of air prduces lift in the front end, so evacuating it helps keep the nose of the car down (you probably already know this). The other way to do this is with vents in the fenders like on Pontiac Trans Ams and late 2nd gen Camaro Z28s. If you look at some closed wheel race cars you will notice that most have vents on top of the front fenders which is the best location to "pull" air out from the fender area because there is a low pressure area there as the air rushes over the top of the car. You are right, though, air coming out of those vents could end up being forced into the vents that supply air to the interior of the car.

Mine are probably larger than the ones you posted, but it's hard to tell just by looking at the picture.

Matt, you mentioned making a template for a customer to use to route out the holes in a hood. Try looking into 3/8 thick lexan at your local hardware store. They should carry 24x24 inch pieces. I have used this several times for making templates for custom pieces that need to be routered with a high speed roto zip into steel.

That's a sharp looking Holden. Are you from "Down Under"? I also like the vents on the new Aston. I wonder if the vents near the rear of the hood are for extracting air or for pushing air into the hood. It seems lie they would act like HVAC vents that most cars have at the base of the windshield which draw air in.

Yeah , I figured they would work great on a turbo car or track-only car.
Maybe on a street car the heat might get introduced back into the interior through the cowl vents.
I'm considering something like this on my '69.
Maybe vent the heat out through the fenderwells or the sides of the fenders.

I currently reside in Sin City. :Alchy: I have a pic similar to this as a reference since I have a pair of T04 turbos waiting for an engine to be built. I too would like a low profile style vent to extract air out of the engine bay. Air going in or out these looked pretty good to me. I like your 2nd gens too because they sink into the hood. I already have a plan to modify them for my ride.
