Here are a couple pics of the new vented hood I am working on. The vent drops 2" down.....is this too much, will this interfear with anyones intakes or strut braces? How is the location of the vent? The vent is 12" deep.

Also, how do the vents in the valance look? You can see where I colored them in, this is where I am thinking of putting them??

The carbon units I am working on are 1 layer of carbon and 1 layer of glass. The hoods are very sturdy. There is no problem with deflection at high speeds. RX7.com has one on one of their "all motor" cars, its is a yellow 1st gen. This car is running in the 115mph range in the quarter with no problems with the hood. I am trying to make a few so if someone orders one I will have it in stock!! If someone requests, I can make theirs either extra thin or extra thick.

 

another

 

The valence looks fine.

That hood vent definately will interfere with my EFI intake.

 

The only thing i have to say, is maybe a little higher up on the valance vents, if its possible. I havent looked at the valance to know if you could or if it would be any better, I ust think they would look more "centered"...or something. As far as the hood, it looks good. Not my cup of tea, but definatly nice looking. I just want either a CF stock hood, or a CF vented hood . Also, are you saying that the CF hoods will be part CF and part fiberglass? No big deal, I was just wondering .

Edit: On second thought, I think the bottom of the vents would look good lined up with the bottom of the headlight buckets...If they arent already...I need to re-check the pic...

 

The last

 

Can someone measure to see how much clearance with the efi and post it on this thread??? I can make the openning smaller...it is not set yet....I could go to 1-1/2" or so??? Also, I will be molding a lip around the opening.

yes, one layer of carbon and one layer of glass. This is what most carbon parts are made of. You would not use carbon for all of the layers unless you are going to put a honeycomb core or foam core in the middle. As Manntis said, it is a waste of money to use all carbon!!

The vents in the valence are lined up with the headlights. If you go any higher, you run into a brace in behind.

 

I already took out the GSL-SE engine, so I can't help you there.

For my scenario, the Cosmo intake is rather large, and probably won't fit with that particular size, style, or location of vent. I think Mike-P was saying his was extremely tight. But that's .0001% of the FB population.

 

I don't think my Racing Beat Holley air filter assembly would clear that either.

 

You'll want the vent much farther forward to clear the dynamic effect chamber in the EGI 13B. The goal of the vent is to evacuate air warmed by the radiator before it flows over the engine anyhow.

I've actually been giving this some thought; ideally if people angled the rad as in a 2nd gen you could have the vent far forward and deeper as on the FD vented hoods. Of course, making this mod necessary to install a particular vented hood would shrink the market considerably...

 

Would someone with an SE measure the distance between the top of the intake to the bottom of the hood? Since my hoods dont have the factory bracing under them(which is about 1-1/2"-2") my vent is about as low as the factory hood!!

Manntis,
I am trying to create a venturi effect??? I would like to do two things...1st do what you said and pull the hot air from the rad. 2nd suck all hot air out of the engine bay. I figure what I have now is just that much more than stock???? What do you think??

Plus, my rad. is going to be mounted like you said and I am also reflecting the air up into the hood and at that point the vent will take over???

 

Oh yah, the vent opening is about 18" from the back of the hood(closes to the windshield). This is pretty close to the front of the motor, no??

 

LOve the vent!! Not sure if it will clear my strut tower brace. if it will, place my order!!

 

I'll try to measure my GSL-SE tonight.

 

the vent has definatly got to move forward. I dont think that will fit any stock intake; series 2 or 3

I wont be able to order a hood of the vent is that far back. Buy the time I ordered a hood, my car will have a atkins 7in with a custom 6inch intercooler underneath it. So the top of the supercharger will stick out the hood.

So hear is my question, if the vent is far enough forward for my supercharger, can you cut the hood?

It looks great though, and the marks on the center valance look great too.

 

as I said,

Would someone with an SE measure the distance between the top of the intake to the bottom of the hood? Since my hoods dont have the factory bracing under them(which is about 1-1/2"-2") my vent is about as low as the factory hood!!

I need some measure ments from the top of all intakes to the bottom of the stock hoods??? help!!!

My car does not have the motor in it

 

After thinking about it, I'm certain that thevent will need to be moved forward towards the radiator. Otherwise it will hit the GSL-SE intake.

As I said, I will work on measuring it out tonight, and will try to make certain that it clears front upper strut tower bars also.

 

Thank you sir!!!




I really dont want to modify it again, but I will if I have to. Give me measurements and how deep the vent can stick down.

Anyone interested in this hood, I need your dimensions also to be sure it will clear. I am only going to make one of these...it cost too much money to make one or two hoods. Although for the right price, I will make a mold and hood for anyone. You would be looking in the $700-$1000 range to make your own custom hood and the more you can buy the cheaper they will get.

 

I like it, good job on it.

 

Not to base on your hood deal, but in the picture at the
top that looks like a steel hood,,because of the brace.
on the under side of the hood, it can be seen through
the cut for the vent. anyway,, the vent should be moved forward some. right over where the fan shroud is..
on the valance how about 1 inch tall "slits" X the same size wide . again,,, thats just my input , or heads-up.
have you thought about vents right over the shock towers ?? just an idea.. keep up the good R & D man...

 

That is the bracing underneath. I do use bracing on the underside and the cut is just inside the bracing...this helps keep the support on the hood opening. There is a cross brace that I had to cut through on that hood. On the new hoods, the brace is moved up about 2". I can take a pic of the back side of it tonight if you would like to see it???


Look at the first pic.......on the other side of the car you can see the backside of another fiberglass hood...see the bracing...I moved it up.

 

Aint no way in hell thats gonna fit over the stock cosmo intake... If you want to know how close the cosmo one is, imagine a regular hood, now scoop the hood upwards like a cowl hood on a ram air TA, thats what Im gonna need.

 

Do you have the stock hood on yours with no mods on the hood?? If so, if I close the vent up by 1/2" it will work. By closing the gap 1/2" it will be equal to the stock thinkness.

 

the end of the vent (lower end) should sit right in front of the alt so the rainwater clears most of the electronics and you pick up air directly from the radiator. i like it quite a bit. i wish i had made mine a touch wider.

 

im not sure aboot the strut tower either...

Screw the louvers, that vent is cool!!!! You comin' out with a carbon-fiber version?

 

not sound mean or anything bad but. When will you have the vallance done that is the only piece i want my hod is gonna have to be modded to hell so i cna't use one but i wish i could. hmmm is there a way to mount the motor a few inches lower? ok when the valnce is one i want one. what is the price gonna run?
