I've read every single post on TGO about the elusive heat extractor hood. It seems to be the "bigfoot" of the thirdgen world. Everyone has seen pics of it, but no one has actually seen one in person.
I took it upon myself this weekend to hack up a base bird hood full of hail dings in hopes of creating the first all steel thirdgen bird heat extractor hood.....or at least my take on it.
It is no where near finished, but after a few hours Friday night, yesterday afternoon, and a couple of hours today I am getting close to having proof that at least one does exist....at least in central Texas.
I have already checked the fitment on the car and the extractor scoop has plenty of clearance above the accessories. I still need to modify the stock bracing to fit in the raised section of the hood and reinstall it.
For the moment I have only roughly ground down the welds. I still need to run a sander over them to smooth them out, and then the whole hood gets a skim coat of filler to smooth out all of the hail dings and any other imperfections.
Here you go.....

Re: The Japanese heat extractor build...for my bird
edges need to be a bit smoother, but damn it looks good.... im thinking itll make a good mold for future fiberglass ones... im up for buying if u ever take that route
Re: The Japanese heat extractor build...for my bird
You are a credit to third gen owners, aftermarket wont make it for us, so we make it ourselves. Keep up the good work, and post your process should someone decide to follow.
Re: The Japanese heat extractor build...for my bird
Here's some of the progress pics from the beginning. Never mind the condition of my car, I know it looks like a P.O.S. at the moment, but give me a month and it'll be back to looking good. It's undergoing some fairly major surgery.
I cut the creases with a cut off wheel in my angle grinder and propped up the center with a 1X2. Then I removed the bracing from the cut section. All the epoxy spots where cut with a sawzall.
I drew a line from 3" in on the sides of the center section near the widshield down the hood to the end of the cut near the nose. The piece on each side of the hood was cut out with tin snips.
A scrap 2X8 was used to raise the center section to my desired height. The cowl is raised 2" above stock from around center of the hood to the rear.
Pieces were cut out steel that I scored for free from work and then tacked in. Of course, measurements were taken to make sure that the raised cowl would end up even/level/square. There ended up being 3 pieces on each side since I was using the 2X8 to keep even height along the hood.
Re: The Japanese heat extractor build...for my bird
Continued....
Here's a shot of the underside with the sides tacked into place. The piece tacked in at the rear of the hood is just to keep it from sagging in the middle for right now. I still haven't decided exactly what I'm going to do back there yet but the majority of it will remain open.
Here it is before I cut the extractor hole. I came real close to just leaving it like this. But, I have another Bird now that will probably end up with one like this.
And here's with the hole cut and the sides getting tacked in.
It all looks kind of sharp and square on the edges at the moment, but I haven't gotten to it with the hammers/dollies yet either. There is still a good bit of small things I need to do to it like cleaning up the edges of the opening to where they look stock and deciding what I want to do with the openings.
Re: The Japanese heat extractor build...for my bird
Lookin great! Please keep us updated with the progress pics! I've been playing with ideas of doing something similar to my Camaro following the lines of the hood louvers. You make it look a lot easier than I expected it to be.

I like the sharp/square-ness of it. Guess with the more rounded noses of the 91/92, you might need it. 90 & before, I think its is perfect the way it it (just finish welded, ground & painted). But I'd rock it, just the way it is too!

You'd sport it around with the primer, two colors of paint, and all the ground bare metal?

Re: The Japanese heat extractor build...for my bird
i like it, just finish it, and if it finishes well, make a fiberglass mold and start production, i'll buy one, or sell it to VFN and see what they do with it.

Or you can be like Kandied and say " Im tired of this, im having this hood made.. i'll post pics with progress..." then a few months later..

" .. and then it goes into Mass production
(Kandied is not really that bad, but he's gone silent until the Car show thing happens and he's already moved onto the next new hotness.... To his credit, he did fork over mad green to have it made, and is probably doing more for the thirdgen aftermarket in this single action than most of the aftermarket... Kandied... WHERE DA HOOD, WHERE DA HOOD, WHERE DA HOOD AT??? )

I don't think there would be any fitment issues with this hood on your car at all. There is still plenty of room under the extractor vent before it collides with any of the accessories/brackets. Once it's finished we can test fit it on to your car to see for sure if there are any clearance issues that would need to be addressed.
Re: The Japanese heat extractor build...for my bird
Made some good progress on the hood this evening after work. Nothing really picture worthy. I made a few more passes over some weld joints that looked a little thin after being ground down and worked the hood over pretty good with a mallet to get the vast majority of the little bit of warpage out of it. I just slapped it back on the car to make sure the hood still fits right since I've been man-handling it and flipping it over and over on the saw horses.
I ordered some perforated stainless steel that will be the "grilles" for the extractor and the back of the cowl. I should get it tomorrow if everything works right.
The stock hood bracing doesn't look like it is going to do much good so I'm going to have to fab up some new braces. But, with the raised cowl and the extractor scoop the hood actually feels pretty rigid the way it is. It doesn't bend or flex when opening or closing it on the stock hinges.
If everything works right I might have it in primer by the end of the week....hopefully. I wont get a chance to work on it at all this coming weekend because I'm going to be replacing a complete rear quarter panel on a friend's 92 Z28. Once that little project is complete I can get back to finishing my car.

No it wouldn't. It would not look good at all. It would look totally riced out. At speed, where the extractors would be functional, the fans wouldn't help at all. If anything, it would disrupt the airflow.
Re: The Japanese heat extractor build...for my bird
The hood project has been put on hold for a few days. I am replacing a quarter panel on a friend's 92 Z28. I just got the car delivered to my place last night.
Once I'm done with that then I'll be back on the hood hard and heavy. I'm ready to finish it so I can do my other body mods and then repaint the car.

OH SHOOT!! That camaro is real bad shape! Good luck with that man
Re: The Japanese heat extractor build...for my bird
That is a very awesome hood. I wish I knew how to weld, but no nothing about metal work. Very nice skills you've got and that's going to eb a very awesome hood when you've got it all done and on your car. Very nice.

That's exactly what the owner of the car said. I have a thread going in the body section of this site on the quarter swap.

I agree. It's basically the same as the first stage of this project. I pretty much turned my hood into a jongbloed before I cut the extractor scoop. The cool thing that I learned doing this hood is that I am almost 100% sure that an LSX truck intake would have fit under the hood before I cut the scoop. I'm planning on an LSX swap on my 89 bird so I'll more than likely build the same hood for it minus the scoop.

Re: The Japanese heat extractor build...for my bird
Okay, I have the Camaro all fixed up with a new quarter panel. All I have to do is put the interior back together and have the owner come get it. I should be able to get back to work on the hood around Sunday.
In case your curious about how the quarter panel came out, here's the thread:
Re: The Japanese heat extractor build...for my bird
I love to see ingenuity like this. Good work! I'd like to see the inverted scoop moved farther forward and the rear of the cowl closed off/blended back closer to the stock heigh of the hood though.

The opening of the scoop is right behind the radiator. I agree, it would look a little better if it was a little farther forward but function before form. The next one will probably end up blending back into the hood at the rear but I figured I'd take advantage of the cowl induction since this is a TBI car.
Re: The Japanese heat extractor build...for my bird
What? Seriously? Must be the angle of the shot because it looks like it's a good 5-6" behind the rad. The only reason I said to bring it forward was to meet the rear of the fanshroud/rad. Good job!
