Intake manifold plate adapter

Abstract

A nitrous oxide plate system having a plate adapted to fit in an intake pathway of an internal combustion engine. The plate has at least one central passage therethrough, and this passage forms a portion of the intake pathway when the plate is installed in the engine. The plate system also has a first spray bar port passing into the central passage, and at least two spray bars that are adapted to be interchangeably installed in the first spray bar port. The at least two spray bars include a first spray bar having a first plurality of distribution orifices having a first total area, and a second spray bar having a second plurality of distribution orifices having a second total area. The second total area is different from the first total area. An interchangeable spray bar for a nitrous oxide plate system is also provided. The interchangeable spray bar has a hollow tube having an interior tube passage, an outer wall, a first end, a second end, and a plurality of distribution orifices passing through the outer wall. The interchangeable spray bar also has a fitting adapted to adjoin the first end of the hollow tube. The fitting has a hollow fitting passage therethrough in fluid communication with the interior tube passage when the fitting is adjoining the hollow tube. The hollow tube is adapted to removably fit within a nitrous oxide plate, and the fitting is adapted to engage the nitrous oxide plate to thereby hold the hollow tube within the nitrous oxide plate.
