something like this but I want to fiberglass it in so it is smooth.

I have a CF hood and plan on painting the outside edges, so the scoop would be painted silver and all the FG would be hidden. It would be purely function, but what do you guys think?

...it would be along the lines Starting is doing, but FG and going in, not up

the functionality of it would be negligible for the amount of work, cost and uglyness you would have to pay...

if your set on it, i wish you the best of luck though

Might be rice, might not. All depends on how smooth and finished it looks. Personally i kinda like it, but it doesnt look very clean...

I've always been a fan of a tasteful functioning scoop. As long as it doesn't look like a snorkel.[:)]

I know there is someone on here that did this. Similar to the Utopia S4. Two triangular scoops/cuts. I asked him to post up a little how to a while back but he never did.

it would definitly look clean, I fucking hate anything on my car that doesnt look perfect trust me...my biggest concern would be the weather, I'd need to make some sort of plug...it would be a pain here in new england, the weather changes as fast as you can imagine

I was planning on doing one of these on my car... Molded into the hood of course for a smooth clean look...

Watch out because fiberglass expands differently from carbon fiber so the seams between the hood and the scoop are very likely to crack when the weather is cold.

good to know...would I be able to use marglas only?

what??? not if you use the same epoxy resin. I don't know how much fiberglass cloth and carbon fiber cloth expands if any i think it would be negligible.

The Fiber Images CF vented Hood already has 2 inlet vents like that.

I just ordered one of these hoods to replace my Vorsteiner hood that I sold to Fred. Mine will match my kevlar doors and will have a black CF frame.

ts all about your resin and also your mixture of hardener. Get a good mix and you should be good.

nice z31 turbo, i always wanted one... i kept the hood off my wrecked a4 for a similar purpose. my good friend is a welder, and has some experiance with autobody, so we're hopefully going to try to make some vents in my spare hood similar to the vorsteiner hood. if it doesnt work out, we'll trash it, its a spare...
but Good luck with the CF/FG, I think it'll be awesome.

keyword search for duct. Naca ducts are the way to go.

I was looking into doing this a while ago for an aluminum hood that I had on a prior car and after going to several body shops, the story was always the same. Every one of them told me that it was not a question of if it would crack, it was a question of when.

I cannot imagine why carbon fiber would be any different since it, like aluminum, expands at a different rate when compared to fiberglass.

I've done it on Corvettes and the fiberglass didn't crack. A few of us are currently collaborating on a new carbon fiber hood scoop for the Cobra and I don't expect that to crack either. We're also doing a new air filter surround and some other intake mods on that car. The hood is fiberglass.

The issue is getting the right resin mix. With a part the size of a Naca duct or small scoop it just shouldn't be a problem.

thanks for the link....I knew "scoop" was the wrong term I couldnt find anything for it...I searched "duct" and came up with a couple things, the one on that R32 came off an old T-Bird

i once had a thought to put a snorkel like this on my car:

but i dont think a hood scoop is really necessary. i dont remember what mods you have, but i cant imagine that you need air that badly. but if you do, go for it. id like to see how it turns out

if you put it on the left side i think it would be very functional... hard to pull it off though

If I end up doing this, it wont be for a while, I have too much stuff going on, maybe sometime during the summer when I get bored and want to do something different...
