I want to make a diffuser/engine pan for my car, and last night I started gluing foam sheets together to make a mold. My plan is to form the foam into the shape I want and then seal it with body filler, and then primer and polish. I have been reading up on making molds for composite work and most seem to talk about making a copmosite piece for the mold rather than what I am planning. If I make my mold as described will my composite part rip the mold apart when I seperate the two? (assuming I use a PVA mold release film).
Also, if I make the part with carbon fiber, how do I finish the edges of the piece when I'm done? I would like to vacuum bag this part because the part will be visible from the top and the bottom... Can I get away not bagging it and get a decent finish? (I'm not super concerned that it has a perfect surface really). -Tony Finished part will look something like this... With the long straight edge meeting up against the firewall and the two tunnels exiting right under the bumper. Attached image(s) ![]() |

A couple of questions, do the exhaust headers drop down each side or run inside the diffuser then out the back and where will the engine cooling air exit from? If you check Patrick's web site, he has a 914 vintage racer that is "canned" in the rear to smooth out the air flow underneath and I remember him telling me it was done as an experiment and the results were not worth all the work involved. Since the firewall is about the lowest part of the car I would want the diffuser to start there?
