A scoop mounted on the carb that stuck out above the hood, to ram vast volumes of air into the carb and get way more horsepower. That's what they wanted you to believe. At 60 mph the pressure recovery would have been laughably tiny, but Ford's profits were impressive. Had a Trans Am, scoop was reversed, facing the windshield, had a flap that opened when MP increased. They claimd that the reversed position was at the low pressure point at the base of the windshield hence enhancing the rammed air effect. I don't know, it was cool, the scoop assembly was attached to the engine so that on acceleration you could see the engine sitting down on its mounts as the scopp popped open and lowere ever so slightly. Locating the scoop at the low-pressure point wouldn't do much for ram-air effect, would it? I think the real idea would have been to make sure the driver heard that thing sucking loudly so it sounded like a real powerhouse I once converted a 14 foot outboard runabout to a 13 foot inboard Cracker Box with a Chev 283 straight-shaft setup. The exhausts were water-cooled and exited through the transom. Made so much noise that I made two mufflers and quieted it right down. The carb's flame arrestor stuck up far enough that I had a scoop on the deck, facing away from the cockpit (which was at the back). Everything else was covered. I dropped my Dad off on a gravel bar on a lake once, so he could fish off it while I ran to the far end of the lake to try the fishing there, three or four miles away. He told me he knew when I was coming back; he could hear that Rochester Quadrajet four-barrel open up and suck vast quantities of air; the boat got one mile per gallon at full throttle with that huge carb. But went real fast. I sold it years ago and I bet it don't go real fast no more, with fuel prices the way they are now. Dan I confess to enjoying ancedotal stories. As a monster nut brat I got some tin cans together and built a pulse jet, complete with a flapping duct input, and used a hair dryer for my air input source, in my parents downstairs fireplace. So I pour in some gas into the thing, lite it up, turn on the hair dryer and holy poop, the duct starts fluttering and flames are fluttering out the ass end! It worked! It buzzed! I probably used a pint of gasoline per minute of operation, but that wasn't the point, it was actually seeing the damn thing in operation. Hands on is good stuff. Please do build another one just like that and put it on youtube, then.. I've only ever seen one person die right in front of my eyes before. Bertie |
