Nitrous Pro Flow 2-stage assembled systems offer the racer the utmost in horsepower capability and the ability to control it. They utilize the same technology as Nitrous Pro Flow's single-stage systems and include all of the same innovative features. These patented assembled plate systems produce more horsepower and provide better reliability than any other system on the market. They provide the cleanest and easiest method of installing a nitrous system. Nitrous Pro Flow assembled systems are the standard in the industry for state-of-the-art nitrous systems. At the heart of the systems is the patented Nitrous Pro Flow plate with its exclusive stainless steel spray bars incorporating "Fan Spray Tube Technology" and burst panel protection. The fan spray pattern created by progressively angled orifices evenly covers the full 360 degrees of the intake plenum to ensure equal distribution and to eliminate corner cylinder lean-out. The burst panels provide protection to the carburetor/throttle body in the event of a fuel system or ignition system failure. The plate itself is fully CNC-machined from 6061-T6 aluminum and is hard-coated for durability and corrosion resistance. They feature high-flow fuel solenoids, high-flow nitrous solenoids, a nitrous purge solenoid, a patent-pending solenoid mounting bracket, and stainless hard lines from the solenoids to the plate. The uniquely designed plate inlet fittings and hard-line plumbing significantly enhance metering capabilities by eliminating expansions in the system that can cause a phase change in the nitrous oxide. The nitrous oxide is purged directly from the nitrous solenoid body. This allows the solenoid bowl to be completely filled with liquid nitrous, which also allows the liquid to reach the plate faster. Completely plumbed and wired into 6-prong Weatherpack connectors, each system is individually flow-tested after assembly to ensure quality and consistency. Stainless steel jet pack and supporting Weatherpack connectors are included, along with detailed installation and operating instructions.
