Hi folks-
New to composites/CF, pardon in advance if I don't have the terminology proper.....but several questions arise as I research and plan this part
The project is an inlet/intake tube - from an airbox or filter to the turbo inlet. Picture attached of the approximate shape, note that there are two 'bungs' or ports or however you like to call them - that connect to the PCV system. They're aluminum the example below but don't necessarily need to be. They're plastic on the OEM inlet.
My thought is to create (carving, sanding by hand) a foam plug, slide a single carbon sleeve over it, wet layup and vacuum bag it. Approximate dimensions are 3" diameter at the smaller end gradually widening up to 5" at the larger end. It's about 15" long in total.
Several questions arise as I try to think through the multiple steps....
-Will the acetone harm the cured epoxy/CF? I've found using a small test piece that the foam melts away quickly with acetone.
-Do I need to wrap or coat the foam with anything before the wet layup?
-What I'm really hung up on is how to add these ports for the accessory hose connections? I've thought of cutting off or removing the ports from the OEM (plastic) pipe and somehow integrating them into the layup? Or, integrating a large nut into the layup, allowing me to use a corresponding male threaded barb as seen below?
The part in the above picture was from someone's DIY write-up for a similarly functioning piece, and thus the inspiration for my project. Thanks very much in advance for any thoughts or pointing out any mistakes in my thinking.

No nothing elegant - good ol' fashioned coreflute. I find coreflute so easy to work with it isn't hard to position it accurately.
