PRODUCT DESCRIPTION
Single Nozzle System for all GM EFI Systems (35-50-75-100-150 HP)
The NX Stage 1 EFI nitrous oxide system is the best EFI power booster on the market. From the machined aluminum and carbon fiber solenoids to our patented Shark nozzle, this system screams quality. Includes a Shark nozzle, mounting bracket, Lightning Series solenoids, stainless steel braided 3AN solenoid to nozzle lines, stainless steel braided 4AN nitrous feed line, 4AN fuel feed line, nickel-plated fittings, wide open throttle switch, master arming switch, 40-amp relay and relay harness, stainless steel bottle brackets, and, in the case of bottle systems, the Lightning bottle valve. This system includes jets for 35, 50, 75, 100, and 150 HP. It can later be easily upgraded to support up to 250 HP. It features the latest technology and the best components available. NX Lightning solenoids feature optimized flow that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in a dense liquid state, allowing for more power with less of it. Lightning solenoids feature an integrated purge port that allows a purge valve to be connected directly to the solenoid body for a cleaner aesthetic and less plumbing. Lightning Series solenoids feature CNC machined aluminum bodies and carbon fiber cases for maximum weight reduction. This system includes a 10 lb (4.5 kg) nitrous bottle with the Lightning 500 machined aluminum valve. This valve not only looks great but also incorporates numerous features, including two integrated gauge ports, a 5/8" (16 mm) siphon tube, a large 0.500" (12.7 mm) orifice, and optimized flow with a single 45-degree bend. The Lightning valve looks great, flows excellently, and weighs nearly a pound less than our old brass valve. If you have an aftermarket engine management system capable of adding fuel with nitrous and would like this system to be completely dry (no fuel components), please contact us.
