ABSTRACT:
A butterfly regulated carburetion system having its outlet connected to the intake manifold by a device restricting fuel and air flow very substantially from the rated flow capacity of an OEM carburetor in a manner promoting improved vaporization of the fuel and thorough mixture thereof with air before exit into the inlet of an OEM inlet manifold thereby to obtain more uniform proportions of fuel and air to each cylinder. These objectives are achieved by provision of a riser plate having a converging fuel vaporizing and mixing passage at least as long as the diameter of the OEM carburetor outlet. When the OEM engine is applied to a typical conventional vehicle, the device provides improved acceleration, better idling, greater power and utilizes substantially less fuel while retaining optimum drivability factor of 92 miles per hour.
