1g vented hood?

[wicked93GS]

ok, I sketched the front of my g/f's 91 laser for this sketch, I thought we needed a decent aftermarket hood for our 1gs, this is just a sketch so bear with me, first off, I wanted it to be functional, so it had to have both intake vents for fresh air to cool the engine and exhaust vents to let the warm air escape, I took the design from a mustang and mixed it with the exhaust vents from some import hood, anyway, let me know what you think, if you dont like it, tell me why, not just that you dont like it, I need ideas here, and I know my sketch isnt the best, but anyway here it is

er, will it work with the rise our hoods have on the drivers side?

 

[wicked93GS]

yep, thats what I'm designing it for, but I need more ideas, thats why its so hard, the middle of the bump ends the part needed to clear the cam cover in our engines, the rest of the bump is simply there so it flows smoothly into the rest of our hood, I'm going to mock up a real model in paper in a couple of days and take a picture, with pop ups though I think it would look better if a headlight conversion were done first, but its designed so that it doesnt have to be, I just need more feedback and ideas, more rounded? more square? any suggestions? constructive please, I dont mind criticism as long as comes with ideas for improvment

 

[wicked93GS]

no comments? come on people, I know the design is kinda lame, I just need ideas, feel free to post pictures of hoods you like that either the exhaust vents or the intake vents rise above the level of the hood(have to clear the bump somehow)

 

[rick]

i think any idea for hoods for our cars is cool. there arent many out there

 

[wicked93GS]

cool, I made a paper mock up today, a crude one, but it actually looks pretty good, tomorrow or monday I'm going to go down to my local newspaper place and buy some thin sheets of aluminum from them(perfect stuff when starting a mold I have found) and continue on it, dont have any film right now though so I cant show you guys any pictures of my mock up(and I already tore it apart, just needed the dimensions) anyway I think it should progress fairly quickly and I'll see how it looks after I have finished the aluminum pre-mold and take pictures if I can snag a digital camera from somewhere

 

[black9d1tsiawd]

I have no advice, I say Good ####in job.

Keep up the good work, take it further!!!!!!!!!!!! maybe u can get a company to help u out with this. I am really in to this idea!!!

 

[black9d1tsiawd]

Are the Intake Vents like the ones on a Predater Hood? if so I think thats DOPE!!!!!

 

[DrZiplok]

There's only one place you want an intake vent on the hood, and that's directly over the MAF. Don't put one anywhere else or you defeat the whole purpose.

The exhaust vent should be more or less directly over the exhaust manifold, but here's where it gets complicated. You don't want to blow hot air from this area directly back over the car, because the cabin ventilation system breathes from the vent directly in front of the driver.

So, to usefully vent hot air from under the hood, you really want a duct on the underside of the hood; something that might be a bit tough to manufacture. 8(

ok, I just want to say, this is not a ram air hood(though I could contrive venting to make it one) I think you'd do better making a ram air intake that takes air in from one of the holes in the front bumper, it would be more effective, but I might make venting that will put the air out over the MAF(I'll test that design anyway),the sole pourpose of this design is to take in cool air at the front of the engine, so the cool air cools down the exhaust manifold and/or turbo if you have one, it then carries that air over the engine to let it out through the exhaust vent, thus cooling down the engine compartment, so bisically the air flows over the top of the engine, taking away the hot air caused by the exhaust, as far as the question about the intake vents being like the predator hood, this design is not like that, those vents are inverted, these ones rise above the surface of the hood to scoop in air as do the exhaust vents to let out the air(though I could make those inverted if I saw a reason to do so or if people thought it looked better) anyway, all I'm saying is this hood is to move the usually pretty still air under the hood back toward the exhaust vents where it can escape, I may do other designs if people tell me the ideas they want done and I can incorporate them into one hood or hoodscoop if possible(it would be easier for me to make hoodscoops the installation of which would require modification of the existing hood, because I really have no way to make a decent hood, I'd have to use hoods from a junkyard or something and do all the molding and that type of thing myself)If I do this though and someone wants to buy a whole hood, I'd probably charge 200+shipping and materials(materials probably wouldnt run over 35 or so if I'm thrifty) for the hood(assuming I could find one in my local junkyard for their 35 dollar price, or somone could send or deliver their own, I dont know) the scoops I would sell for 100+shipping and materials, but if I do this I wont be able to mass produce them so they will take awhile to make, anyway I will make several designs on suggestions I get from you guys, sorry about the long post

 

[black9d1tsiawd]

Aight Man, Just keep up the Good work and keep doing what ur doing. I like the inverted vents I personally feel they look better, and would suit the design better

 

[wicked93GS]

I'll draw up a design soon using inverted vents(though I dont like the idea of water leaking into the engine compartement if it rains)

 

[wicked93GS]

ok, heres some more sketches for you guys(though one isnt really functional, ignore the writing, the scanner kinda reversed it so it doesnt make sense now

 

[wicked93GS]

and my last set....these arent too great, the first one was kinda inspired by the old beretta hood vents, the second inspired by the formula firebird ram air hood in the 70s

 

[wicked93GS]

I think the 2nd one looks best, but I dont really see a way to make it functional(well, I suppose I could duct it to a CAI, but that would require MAS relocation and a special filter fitting, lots of trouble to make it functional)

 

[wicked93GS]

this one is absolutely ridiculous, the exhaust vents in front would be functional, but the intake at back wouldnt be, unless I made it a ram air type thing, but with the hot air coming from the exhaust vents it wouldnt make much sense

 

[wicked93GS]

and finally my masterpiece(my new favorite) this is an evo-type hood so it retains the DSM look, even if not the eclipse look, I think everyone will like this one best, it has vents that can serve as both intake and exhaust, covered by a screen(only problem here is rain, I can always make a clear cover or something to protect against the rain or something) but I now like this one best, sorry, I wont post anymore of them unless asked, tell me what you think!

 

[Lancer14]

Keep it coming with the concepts.
I personally like the style hood that Taboo Speed Shop is working on. I also like the power vent on the Evo hoods, however it would have to be on the opposite side for a DSM

the only complaints I've ever heard from Mirage guys about the vents on the Evo hoods are that you have to clean the water spots off of the engine after it rains.

I like this idea. the evo style hood is prob. my favorite design, but there needs to be a good way to cover it when it rains.

btw, what the hell is with that evo? there is a racing seat on the left side which is where the steering colum should be...yet there is a stock seat on the right side along with the steering column?!?!?!?

 

[wicked93GS]

hmm, thanks for the feedback, I like the idea of a power vent too...I can put one into the Evo type design, as for covering it when it rains, I can fabricate some kind of clear plastic cover...but you'd have to carry it around in the hatch or something, not that it would weigh much, but it would be a pain to keep putting on, as far as the evo in the picture...the guy probably had the column switched over for driving in the states, you can get that done to foreign car I'm pretty sure(who knows whats up with the one racing seat though), thanks for the pictures, I'll keep the concepts flowing then as long as I can think of any, I had to angle the front so it will clear pop ups, I think it looks better angled too, but anyway, thanks

 

[ceniack]

why not design a pop-up cover that you can put on the passanger side pop-up light that makes a scoop (similar to some i have seen for the 240sx) you wouldn't have to make an entire hood, and it would be cheaper to produce (using fiberglass or plastic) would looks sweet, and would have a psudo-ram-air effect.

 

[wicked93GS]

that would be good for the intake(just take a pop up hood and put it on a non pop up car and you can get 2 ram air intake type things to vent to the MAF)but I still need to let the exhaust heat escape and besides, the whole hood just looks cooler, he he, I'm going to make an EVO type hood for myself anyway, and anyone else who wants one for a couple hundred(plus the hood either from my local junkyard as long as they have them or from the person who wants one themself and supplies, and at least part of the shipping) not really trying to make a lot of money, but it does need to be worth my time(and besides, I have an engine build to finance, he he) it will probably take some time to make each one, but I need something to fill my spare time anyway

 

[black9d1tsiawd]

Dude, Iam inlove with the Evo Style Hood!! That has 2 get made, Seriously just continue on that design. Try to cover as many angels as possible, and if you want I can contact a few companies and see what can be done.

you might want to think about these points before you do a whole ton of work on a hood. just thought that i would re-iterate the post.

well, the intake over the MAF can easily be taken care of by the EVO power vent that lancer mentioned and showed with his pictures(thanks for the pictures by the way) as for ducting for the exhaust on the underside of the hood....show me a picture of the underside of that Evo hood and it would help, but I'm sure I can make something for that

Talon TSI AWD, let me get a hood finished first, then you could contact companies(hopefully I'd get some type of royalty or something for it, he he) anyway, once I get a hood finished I'll throw it on my car and take some real pictures(on both pop up and non pop up?91 and 93)but I'm going to go buy some aluminum sheets today to start the pre mold for it
