That said, for such a big part with so little detail, that really shouldnt be hard either. Anyone care to guestimate what the hood scoop would run? I guess about $275-500 IN cf.
There are different methods in fabricating carbon fiber parts. The most common and cheaper method is the wet layup technique as JohnnyAppollo had briefly described earlier. Most auto accessory fabricators do this as it is the cheaper technique. With this method, you won't get a real perfect part as it is proned to bubbles during the curing stage. To get the bubble-less part, I believe you'll need to use prepreg carbon fiber material which already has resin saturated within the cloth and bake it on without the bubbles. Also, using the common vacuum-bag technique will reduce the chances of bubbles in the resin. Both latter methods are more expensive to do and the costs are passed down to the part along with labor.

Regarding the negative buck, that can be made out of regular fiberglass and resin material. The most difficult part is having to make sure that the buck mold is as perfect as possible without any flaws of any kind. Otherwise the molded parts produced from the buck will reveal each flaw in the end result.

This, of course will require your typical manual labor of sanding and re-sanding to perfect the mold. And if your parts also still reveal other unforseen imperfections, depending on how anal and patient you are, you can spend a few days or more trying to get it right.

The art of fiberglassing is unforgiving and takes time, effort, patience, and the tenacity to strive through major F' ups along the way. Much luck if you plan to pursue this.
