About item:

Nitrous Express has spent countless hours on the flow bench, eliminating these turbulence points in its systems to minimize the boiling of the nitrous charge.  NX has designed its own bottle valve, which differs in many ways from the standard or even custom valves offered by the other companies.  The flow path of the NX “Lightning” bottle valve has only one turn, a 45-degree angle to the discharge point.  This eliminates the harsh 90-degree turn present in most bottle valves.  One company that boasts of its “Super High Flow Valve” has designed one 45-degree turn and one 127-degree turn inside the body of the valve.  This severely restricts the flow and causes a turbulence point that sends a diluted flow of nitrous downstream to the nitrous solenoid.  Finally, the style of bottle nipple used by NX allows the nitrous to transition from the valve to the supply hose with no internal steps or restrictions.  These things may seem small or insignificant to the layperson, but on the dyno, NX systems make more horsepower per pound of nitrous than anyone.

Nitrous Express Lightning 500 bottle valves feature a .500″ orifice and a direct flow path that eliminates those power-robbing gaseous bubbles. The result is more horsepower! The Lightning 500 will outflow any competitor’s valve on the market today and is recommended for all nitrous systems up to 2000 nitrous horsepower.  The 500 has a .625″ siphon tube, only one 45-degree turn in the nitrous flow path, and fittings that will allow the use of up to a 10AN supply line with no restrictions. The 500 is engineered to eliminate all obstructions, sharp edges, or tight turns that will disrupt the smooth laminar flow of nitrous. This design minimizes boiling and gaseous nitrous in the flow path to the solenoid resulting in a nitrous system that produces more clean horsepower and is easier to tune on any car! The Lightning 500 is CNC machined from billet aluminum and is approximately ½ pound lighter than a comparable brass valve, it has dual gauge ports and interchangeable nipples that will allow the use of 4AN, 6AN, 8AN, or 10AN supply lines.
