I've recently given fiberglassing a shot, I like it. Its easier to make more complex shapes than with metal. I'm curious as to if I could make part of my intake manifold out of fiberglass and not have it explode/collapse under pressure or vacuum. My plan would be to make a frame for it out of heavy metal screen, lay a few layers of glass over the top of it, flip it over, and glass on the inside as well, so the metal screen is embedded in the fiberglass. I would probably incorporate a few metal pieces to strengthen certain parts of it(near the throttle body for example).
Would this work, or am I wasting my time?
