Custom Reverse Hood Scoop Idea part 2

stentorian 11-07-2006 08:12 PM

[QUOTE=eric rxb;15844264]Generally pre-preg is still laid out onto a mold, but instead of applying resin as is the case would to the fabric type, the pre-preg is placed into an autoclave where the temperature and pressure force it into the shape of the mold.
[/QUOTE]

That describes the process a little better;), the carbon fiber used is aerospace grade. As far as using a CNC to cut out the exact shape you want, that would be more for things that are more flat and have no mold to use. Here is a pic of a scrapped piece that could be used for the outer part of the hood vent deal, where the screen could be attached to. A CNC machine will be able to cut it precisely to the specs needed after all the layeres are layed out and then put into an autoclave. Then you ask what about the center part that is cut out, no it's not turned into trash, but some other parts I am working on;). Then after all that it can be clear coated or whatever else:D. It's hard to get into without writing a book here.

This one is sweet. I'd buy one if it looked as nice and was <$100

I'm working on this, but my vendor is letting me down on delivery. Some changes I've made and things I'm working on:

- frame is more flush with hood and doesn't stick up as much.
- better fit.
- frame is narrower, so the opening is a little bigger.
- reduced cost, easier to fab.
- louvered panels for underneath.
- different mesh types (the best one above is steel unfortunately).
- '02/'03 and '06+ versions

I'll post pictures when I have something worth showing...

Making from carbon fiber sheet is expensive, because it's wasteful due to the big hole in the middle. Molding it in the shape would be the way to go.

I would love to be one of the first on the list to receive a vent for an '04/'05 design :)

What are the louvered panels? Something under the hood?

Thanks,

Dinko81 11-28-2006 09:29 PM

Forgive my ignorance but how does the vent fare in the rain? Would it be damaging to the engine to have water go in? I know the EVO has a similar setup but I have no idea how they handle it, plus that vent seems to be closer to the front rather than directly above the engine.
skate enjoi 11-28-2006 09:37 PM

if you think about it, you would get a lot more water, snow, birds, random crap in your engine with the stock hoodscoop that the wrx's came with.... thie would be for hot air to escape.... and what ever happened to this? seems like the idea just died.....

i don't know about that. i feel kinda uneasy about water poring into my engine bay when the car is parked. The hood scoop keeps that from happening at least.

whoops, missed that... but you can count me in for sure
clutchcargo 11-29-2006 01:46 AM

Count me in for one of these, shipped down under.

And this would certainly be for FMIC guys only. The scoop and rubber surround are mandatory to keep charge temps down. (even guys without the rubber surround and scoop have reported knock issues that were solved with a sealed scoop).

And just a word on the water entering the engine bay, at speed there really isn't an issue, and quite a bit gets in through the front air dam etc. However an option for a solid peice to slot in (e.g. ferrari clear perspex style!) would be pretty cool and would allow the FMIC guys to keep the lighter hood.

:) I've changed my mind.
knucklesplitter 11-29-2006 05:53 PM

The vent I'm designing is very modular. Just about any piece of screen, mesh, or sheetmetal can be cut to fit under the frame. It would be easy to have pieces of lexan cut to block off the hole if somebody is worried about a little water on the transaxle (the hole mostly sits over that anyway). Also it is all stackable, so if somebody wants lexan then mesh then louvers then more mesh... it's doable... silly, but doable. ;) I should have unpainted frames and some mesh (plain and powder coated) in about a month or a little longer for '04/'05. '02/'03 and '06+ about a month after that.

any update?
knucklesplitter 01-04-2007 07:58 PM

My project is delayed. The mounting has been redesigned (for the better) which is good. But it seems like on the last two prototypes the fit into the scoop hole was worse!?! I think there are variations between the three different suppliers I've used, and that needs to be figured out and fixed too. This new thinner version and the larger opening look great though. I would now anticipate the '04 version to be ready in early Feb. Sorry, but I am pretty picky and I won't call this done until the fit is right and the details are worked out.

Maybe some will be black anodized or powder-coated semi-flat black too. Would that be something that somebody would want?
clutchcargo 01-04-2007 08:32 PM

Definitely count me in for one of this knuckle, shipped to melbourne. From what I can remember, the evo shroud is a flat black, so thats what I'd be shooting for (rather than anodized or Pure White).

[QUOTE=SparkysJDMSpeedWagon;16587318]*drool* Count me in on flat black or black anodized with louvers![/QUOTE]

Louvers *maybe* in March. I've got two ideas:

1) A louvered panel that sits inside the normal frame hole - kinda like louvered slats that tilt back. Could be painted to match the car's color or black. You'll see this look on some race cars, Vipers, and dare I say the Hummer (but don't judge it yet!;) )

2) A black louvered panel that screws in place of the stock IC splitter (that's gone anyway). Actual punched louvers that sit below the mesh installed in the hood vent. This is kinda what the EVO is like. This could maybe help those that worry about rain on their tranny.

That Roger Clark scoop is smooth looking, I just wish I could get a reverse scoop like that without going to front mount. How about we get someone to design a reverse scoop like that for us TMIC guys :cool:

It would be hard to get enough airflow through the IC with a reverse scoop. I doubt it's feasible. If it were it would prolly have to go all the way back to the high pressure area where the windshield meets the hood (like the old Chevy "cowl induction" hoods on '67-'69 Camaros and '70-? Chevelles). I still don't think this would be enough for adequate flow.
Maccgyver 01-10-2007 01:49 AM

I am opposite from most on here, I love the big scoop and was happy I could find a STI hood for cheap for my wagon. :) I love the aggressive look. Better watch out or you will get sucked in.[IMG]http://www.gooterbash.com/gallery/albums/userpics/10040/stiscoopside.jpg[/IMG]

Yea, I know, I just wish it wasn't so. I really don't like the huge thing on my hood, but don't think a front mount would be worth it. Maybe some day when I'm rich and famous or something :)

There will be some changes on the ones being made this week:[LIST][*]Better fit into the factory hood-scoop recess - OEM quality.[*]Flush with hood (not sticking up like in pics).[*]Larger opening in the frame.[*]Semi-flat black powder coat option.[*]A second more-open mesh.
[/LIST]Like the one in the pics it will have the following features:[LIST][*]CNC-machined from 6061 aluminum plate.[*]Uses factory scoop-mounting holes - no drilling required.[*]No hardware showing on the exterior of the frame.[*]Includes stainless hardware.[*]Easily reverted back to stock.[*]Grillcraft mesh option - powder coated.[/LIST]

I hope to have pics this weekend, if the machine shop comes through on the first article due this week.

clutchcargo 01-29-2007 05:50 PM

"There will be some changes on the ones being made this week"

Yep old pics, but looking forward to the new ones knuckle. Definitely needed to be recessed (I'm sure from the drivers seat its driving you crazy with it sticking up like that, even though you can't really tell from the other shots).

But otherwise its a great bit of kit, I'm thinking of getting some automotive-grade clear perspex instead of the grill to show off the pipes (ferrari style hehe) do you think that would be possible?
knucklesplitter 01-29-2007 06:05 PM

Yeah, the prototypes I've been having made the last couple months have all been just to get the pattern/thickness/hardware right - they were not fully machined with radius and such. These things are expensive to just have one made, so I cut costs to just work on the shape. I refuse to post pictures of those, because the way these forums work they will get thrown around like that's the final version.
