Re: Help me design a carbon fiber intake manifold.
I would go as far as to find an industrial strength primer that you can paint the tops of the stacks with. It doesnt need to be noticable, but all the mating area plus about .050". Hardly anyone would see it, and you would be sure not to have corrosion (at least for a long time ).
Can't wait to see this get completed. EDIT : Also, what are you doing for gaskets between the manifold and the stacks?

The runners are going to be tricky as ****, but I think I've got a process nailed down reasonably well. I'll do a full update on that aspect in a bit. Quote:
Gaskets are just going to be the OEM ones. I haven't goofed with the dimensions of things or ported the runners out to the point that I would need different gaskets.

Re: Help me design a carbon fiber intake manifold.
lol, nothing super new at the moment. Molds are now sanded, sealed, painted, cleared, wet sanded, polished and waxed. I have all my CF and epoxy ready to go and am planning on laying up the plenum halves tomorrow night (if I have time... Going to some musical thing for the girlfriend). I'll take some shots of the molds, layup, and runner jig tomorrow.

Re: Help me design a carbon fiber intake manifold.
Update!
Molds painted and prepped: One plenum half laid up and bagged: Got it out! Got the second one too! (this one brought a bit of its mold with it) And the runner layup tool. The vertical plate has six different holes on the back the correspond to the individual runners. Bolt the upper mandrel in place, fill the gap with foam, and voila, runners.

Re: Help me design a carbon fiber intake manifold.
So are you sure you can't make another one??

Re: Help me design a carbon fiber intake manifold.
There's nothing stopping me from making a second one, other than time and money, and access to a CNC mill. I doubt it'll happen though, I only need one and it would cost quite a bit for someone to commission me on a second.

Re: Help me design a carbon fiber intake manifold.
Small update: No new parts made since I've been working on the report that accompanies this project (currently 32 pages long... my fingers hurt), but I have an estimated final weight for the manifold.
*drum roll*...... 5 pounds. And that's a conservative estimate, I weighed the parts I have which are untrimmed, and the flanges I've already machined, and extrapolated a bit. I wouldn't be surprised if the weight actually turns out to be closer to 4 pounds.

Re: Help me design a carbon fiber intake manifold.
What's the stock manifold weigh?

Re: Help me design a carbon fiber intake manifold.
If I had to guess I would say 15 pounds. Total shot in the dark, though.
