The mystery of why this intake did not work, has been solved. The theory behind it was that if fuel were allowed to condense on the walls of the tube and run into the cylinders at random, in little puddles, that would make the engine sputter badly from suddenly going rich. This is true. The solution was to make the intake so that the puddles could not make it to the cylinders. The solution is the problem because the puddles then just congregate in the lower part of the manifold and when the air flow is increased such that it starts sucking up these accumulated puddles, the engine goes way too rich. An expensive experiment, but now I think I know more about what works and what does not. I am getting new bent tubes on Friday, and will have a new intake to try very soon. Who knows, I might just make it to I39 this year.
