Nitrous Injector Machining

Yesterday I completed the machine work one the forward closure and nitrous injector per the specs given in the motor schematic. Here are a few images of the forward closure with the injector installed. The injector itself contains a compression fitting for the thermoplastic tubing that prevents nitrous flow prior to ignition. A pressure tap (small hole on the right side of the injector face in the image below) was drilled through the closure and adapted to 1/16" NPT in order to measure motor internal pressures and the pressure drop across the injector.
