Default DIY CF Engine Cover?

I need a small project, so I started thinking about an CF engine cover. I've made one for a different car with another ugly intake manifold and it came out pretty good. It's fiberglass mat over a male mold, then a CF overlay with surfboard resin. For the C8, I'd do the same. It'd end up pretty big, 24" x 20" and cover a good portion of the center opening. I'm thinking some polished corvette emblems for the top but that's still up in the air as decals of some sort are still in the running. It'd be attached to the existing OEM cover with some small spacers raising is some.

What do you think, yay or nay?

Always nice to have a new project. Sure, why not, you have the skills.

If it were me, I'd probably add in some indentations, lines, etc. As it stands, that's one large expanse of CF... I'd prefer to see it broken up a bit rather than one large table.

Sounds like an interesting project and if you have the skills needed to work with CF and fabricate a cover, go for it.

Yes, I agree. I've ordered a round emblem from a 1960 Corvette. I'll install it recessed, well at least that's the plan. Not exactly sure what the diameter is yet, but I'd say at least 4-5" so it's a big piece. I like the juxtaposition of the carbon with a trim piece as old as I am LOL. I've also found a place that does custom stainless trim pieces. Not 100% sure about those as of yet though.

On a different note, male mold is built, and resin came in last night. First layers of glass go on today.






This emblem will have a trim ring around it. Car is Artic White.

Looks good, but I would rather see a stylized intake plenum, rather than a cover for it. The Z06 intake plenum looks good, but the Stingray intake is ugly (at least some think). It did not have to be that way.

Couldn't agree more. The plastic milk crate look leaves a lot to be desired. This was the previous motor I built one for. GM 3.6L LFX.

I like your idea of incorporating the 58-61 emblem into the design. Always thought they were nice.

Work is progressing, Multiple layers of glass and carbon as a base and a final layer of carbon. This is first coat of resin over the final carbon layer so a bit rough. I did get the emblem in today. The good news is the size is perfect, the bad news is it's clear which doesn't really work. What you see is a piece of white construction paper behind it to give the contrast. I'm going to need to paint the backside white. Lots of sanding and more resin coming.

This coat of resin doesn't want to dry fully, it's been quite a few days and still smears a bit when I sand, and it needs to be block sanded before the next coat. This piece may be headed to the trash. I did order more supplies. Like my father used to say, 'nothing money won't fix' LOL.

If the sun ever comes back out, I'll sit it in it and see if it moves it along.

I was able to save that piece as I ground off that last coat and installed another. A few more coats of surfboard resin, a lot of sanding and we're good. Stainless strips are on the way. Just need to figure out how to mount it.

Great. Something different certainly is up my alley. With a history of aluminum fab, were it me that's the way I'd go. The car already has enough "plastic" from GM.

Studebaker dry-sump pan, for example.

Perfect! Can you fabricate an attractive aluminum intake manifold to replace the "ugly" composite one, making it unnecessary to use an ornamental cover? I'm serious.

Could use a look like equal length intake tube injectors or 4 side draft dual throat Webers!

Project got put on back burner a bit as I struggled to figure out a way to mount. Ending up finding some Ford parts used to mount intake covers on a number of their vehicles. 6 sets were $42 so a little pricy. I just completed the front attachment. Will start on rear this week.

So, the font has three prongs that push into the socket vertically. I had to make the prong holder and epoxy and fiberglass it to the cover. The rear will then push down into the sockets. Well, that's the plan.

It struck me I never updated this thread. I did make a rear mount that attaches to the cross brace between motor and trunk. Three more of those Ford push in connectors. Note both chassis mounts are removeable. Locks it in quite well. For what it's worth, this one's done.
