100% CF autoclave hood, ~9lbs interested?
�
�
I'm considering making a autoclave 100% carbon fiber version of the 2004+ wrx/STi hood. I'm wondering if anyone's interested?
in order for this to become a reality, I need a lot of interest becasue this will be a large investment. here are the proposed specs:
exact replica of the stock 2004+ WRX/STi hood. cutouts for washer and scoop. mounts to stock hinges, but must use stock prop stick (no installing lifts for you)
another option is making it a replica of the Prodrive WRC hood. with the front vent. however, they'll ALL have to be made like that.
weave: 1-2 layers of 3x3 or 1x1 cf, depending on the price differrence.
net weight of hood: under 10lbs
strength: strong enough so that you can lean on it w/o damage. will support small girl ~100lbs laying over it. =)
cost: ~750
note: there is a possibility of useing the stock latch, but it's safer to use hoodpins/locks.

If you can do it, More power to ya! Though somebody else tried this, and needed half down to do it, and managed to rip a whole bunch of people off in the process. I think his name was ScoobyRS or something like that. Good luck though, if you can pull it off, make some for '02 style too.

definitly would be interested, replicate the chargespeed hood, with the vents so that we can get some real good cooling.
| aznatama | 08-23-2004 05:08 AM |
if I get enough interest, I would be 100% willing to go ahead with production, and would not require a down payment. After all, it's a business investment, and that's why I'm trying to assess the risk involved in the process.
as for the chargespeed hood... do you have pics? I've only seen the normal stock replica one.
if you're interested and can SERIOUSLY pay for it then please post.
as for pics.. just imagine a 2004+ STi hood or the Impreza WRC car in full carbon fibre, and weighing in at under 1/2 the stock hood weight.

Very interested, You will get many who go the front mount direction who want to ditch the scoop and get so difusers to get the heat out. Me for one :)
| calworld | 08-23-2004 04:59 PM |
I will buy it if it is the cusco replica one
| OneManArmy | 08-23-2004 06:23 PM |
I think you will sell more if it's just a stock replica....but that's just me. A lot of people do dig the cusco hoods.
for that price.....you're gonna have to make a few to show how good you are...that is some serious coin.

that's why I need to test the waters and see how much interest there is in a fabrication run like this.
| b57m57w57 | 08-23-2004 07:34 PM |
Would you plan on doing two hits with honeycomb between the layers? If so would you use film adhesive and autoclave the first and second hits? I am trying to get some idea of the methods you would use. I just like to see the different ways different shops go about the process, that's all.

| aznatama | 08-23-2004 07:36 PM |
that would result in a rather thick hood....
a double/single layer of dry carbon is sufficient for the stiffness and strength required in a hood. it'll already be stronger than the VIS overlay version.

Well you could do one layer of 3K 4x4, then 1/8 or 3/16 aluminum or nomex honeycomb, then one more layer of 3K. It would be pretty strong, not that thick and weigh between 8 and 9lbs. I just think one or two layers with no honeycomb would be kinda weak. Just my opinion.

I would do the layer of carbon, nomex homeycomb then another layer, thats how a local shop did a bunch of vw hoods, and i could stand on them and there would be no ill results. is this the cusco hood your talking about?

actually, I was thinking of the prodrive WRC hood... like a replica of the rally car with the front vent.
well, whatever has the most interest... most likely it's going to be a stock replica though.
I'm still researching layup methods right now, and I'll let you all know once I figure it out.

i would be down for cusco hood pictured about in full cf. If the quality is perfect I would have no prob paying $800 for it.
| Sc3pt0r | 08-24-2004 07:59 AM |
dunno about 800 but if it was a PERFECT replica of that cusco one and 9p's then ya...bc i like the look of the stock hood but i got a fmic so i'd like some more 'reverse hoodscoop' type action of venting air out..which would make THAT hood damn near pefect :banana:
| Phat04WRX | 08-24-2004 01:36 PM |
I like the WRC hood as well.
| aznatama | 08-24-2004 01:52 PM |
i think a WRC style would benefit a fmic more than the cusco-style hood, but I'll setup a poll once I'm ready for production
| FortyTwo | 08-24-2004 07:07 PM |
Too bad its not for bugeyes...
| Ravenous | 08-24-2004 07:13 PM |
i think you have alot of people interested .I am as well.Hope it works
| kunfuzion | 08-24-2004 07:53 PM |
the WRC hood/vent will only benefit the all the FMIC guys, it'll just cause cooling issues for the TMIC people. i'd be interested in a Cusco or even an OE style.

Definately the WRC hood for me. I am very interested in that hood, I just need to figure out how to nicely get rid of the scoop in it when I go to an FMIC. But I still like the vent in front of the scoop.

With the WRC-style front scoop, wouldn't you also be cooling off the radiator more, if you had a top-mount? Besides, if you're hard-set on an OEM-style hood, there are already many of them made. How many companies make the Prodrive/WRC-style hood?

| Cadaver | 08-25-2004 01:24 PM |
I'm with the majority. I'd purchase one if it had other vents to relieve the engine bay of some of the heat. For something basic, I'll just stay with stock hood...

the wrc car doesn't have a top mount, they mount it v-style inbetween the core support in the front grill, thus not really affecting the functionality of the scoop. true the vent pulls heat from the radiator, but do the tmic guys really want all the heat to go into there i/c? there are other efficient ways to pull heat, alas the cusco or cwest hood. not trying to argue, just stating design factors.

actually, all the cf hoods made so far are overlay and inferior to the one I'm designing.
as for the earlier comments about the honeycomb inner structure, that is a possibility, but would increase costs a bit, but hopefully would still be under $800 per hood.
Do you think the VIS hood a good quality cf hood?? I've had several VIS hoods and I don't think they're all that great. Their hood, along with many other overlay types literally costs about $150-200 to make, and they're selling it for $5-600. 200% profit margin. they use one sheet of cf which has a WET LAYUP and most of the time has some air bubbles in it. Then they use several sheets of fiberglass matting to build up the stiffness. This makes it relatively heavy. Also, the OE mounting points of the hinges are usually inserts (a nut embeded in the resin) which will eventually come loose after prolonged use.
The specs for teh hood I'm planning on manufacturing uses a sheet of 3k cf on top, then a honeycomb structure underneath, and then another layer of cf on the bottom, followed by a reduced version of the OE skeleton underneath to provide stock mounting points.
This is the same method (cf, honycomb, cf) used in an aircraft wing, and yields an extremely stiff product that WILL NOT FLAP AND BUCKLE at speed like the stock hood, and other overlay hoods.
100% CF by nature is very flexible compared to fiberglass, but when you're using sheets of it, it'll still be flexible.
To my knowledge, NOBODY in the industry uses a honeycomb structure in their hoods becasue everyone want's to have a high profit margin. I'm pretty sure I will be the first one to have such a hood constructed and commercially avaliable.
Cost will be around 800-850 shipped to your door, but depending on how many I can sell, it could be as low as 700-750 shipped. for now, I will be working with an OE replica becasue it seems like that's where the most interest is.

Are you going to use a stock 04 hood for the mold?
| aznatama | 08-25-2004 02:49 PM |
for now, I will be using a stock 04 hood as the basis for the mold.
this is the plan I have so far.
-replicate the stock oe hood.
-sell at least 25 of them
-use profits generated to help buy genuine cusco hood and begin production of cf cusco replica
I know there are ppl out there who just want an oe hood, so that's where I plan on beginning.
the OE hood is easy to replicate becasue it's already finished.
if I wanted to replicate teh WRC hood or cusco hood, I'd have to buy it, completely fit and finish it so that it fits perfectly and the surface is flawlessly smooth and flat. that take a bit of work for any of you who've worked with fiberglass replicas before...

now that would be cool if you did an rs hood too... for the 04... but good luck man... i know how pain staking it is to work with those materials... Let me know how they turn out...
| aznatama | 08-25-2004 03:04 PM |
RS hood's aren't popular, so unless you're willing to pay double the price... it's not worth the investment. sorry.
you could always get a reverse scoop for the WRX hood tho.

well lucky me i have a 2002..so much for the WRC idea ..guess the stock hood will just have to do for now. PM me when/if you decide you can do something for me for my fmic.
| FryRice | 08-25-2004 04:37 PM |
did you started yet? plus do you have any previous experience on cf? pic on work you have done?
not to be a nut... a mod going to look at this and close this thread because you have no vender stats....... you shouldn't talk about the cost.

cusco doesn't have an 04 hood yet. seibon made a replica of it for the 04 though. hope this thing doesn't flop. anyways, any chance of a dry carbon version?

I like the honeycomb idea. More strength and lighter than the stock hood, very nice.
| aznatama | 08-25-2004 07:53 PM |
I'm not the one making it, I am currently reviewing several manufacturers who deal with carbon fiber.
why can't I talk about the cost? I'm not collecting any money from anyone... I'm just letting people know all the information so I can get a somewhat accurate idea of how many people have interest in a product like this. If I decided that there is enough interest, I will then either apply for vendor status, or sell it private party as a hobby-sale.
I think I'll start with the OE version and see how things go. This is a very large investment on my part, but I like doing things like this. =)

I guess I am not going to fix any time soon my dent-ed aluminum hood (or buy an after market cf) by two tiny rocks thrown from the construction truck in highway. T.T
Investing a couple of hundreds of bucks more for a cf hood instead of taking the car to the bodyshop for heating and buffing would be better decision, IMO. hehe.. more character to my car..
If everything comes out well, I would like to have a look and replace my poor hood. By the way, I like the reverse air intake model (though I don't know how efficient it is)... It looks flatter than the scoop-version. What happens if it rains a alot in the engine compartment if the hood has lotta holes or grills like the cusco ones?
Also I am just wondering.. how reliable and durable the 100% cf hood would be?? I am not worried about the weight that much.. I just don't want to have another easy dents or fiberglass cracks..
