Nitrous Express Lightning Solenoids

Nitrous Express Lightning solenoids are designed to strike with efficient performance. Each is created with a raised inlet and a bottom exit that eliminates up to four 90 degree turns and one expansion area in the body of the solenoid—making it more effective to maximize power. Plus, each NX solenoid has a bypass (purge) port which allows you to connect a small bypass/return line to your tank; or connect a purge valve directly to the body of the nitrous solenoid, thus ensuring there is no trapped air in your system. The replacement solenoids are CNC-machined from lightweight billet aluminum, anodized, and then topped with carbon fiber cans for the ultimate in weight savings and appearance. Amplify performance with bolts of horsepower from Nitrous Express Lightning solenoids. They're available in a variety of sizes, flow limits, and types—for either nitrous, gasoline, or alcohol.

Nitrous Express SAFE Systems

Improve the performance of your nitrous oxide system with one of these Nitrous Express SAFE (Stand Alone Fuel Enrichment) systems. They feature a one gallon, high-strength composite fuel cell that can be mounted in most factory battery trays without modification. The systems are also available with a high-output, internally mounted fuel pump and an adjustable external regulator, making installation quick and simple. When used with gasoline, they can support up to 800 nitrous horsepower. When used with methanol, they will support up to 400 nitrous horsepower. When used with race gas or methanol, the need to retard timing is significantly reduced. Often, on V8 engines using nitrous boosts of 150 hp and above, zero timing retard is required. The Nitrous Express SAFE (Stand Alone Fuel Enrichment) systems reduce the need to upgrade OEM fuel pumps and will completely eliminate pressure drop at the fuel rail in EFI vehicles. They also include an integrated fuel level gauge and all mounting hardware for a no-hassle installation.

Nitrous Express HP Jets

Many racers casually assume that a jet is a jet--all created equally. However, Nitrous Express suggests that precision manufacturing and design can make a big difference in performance. Their HP jets are CNC-machined and guaranteed to be within 0.0005 in. of the specified size. But the real advantage is in their carefully contoured, multi-step outlet, which reduces turbulence and increases flow by as much as 35 percent over competitors' jets of the same size. Nitrous Express offers brass flare-style HP jets in dozens of sizes to accommodate virtually every system.
