ok, since Im going to be fabricating kind of based on what you have, I was interested in what you were going to do to remedy the diaphragm problem. Perhaps bringing the front w/g forward off the runner towards the headlights and extending the dump-to-dp pipe to the same location and extending the rear w/g rearward and have it dump further down in the dp. Hopefully water-cooling will help and I can copy that too lol. Good luck.
