NOS Dual Stage Big Shot Nitrous Oxide Injection System

The NOS Dual Stage Big Shot Nitrous System is a competition-grade, wet nitrous oxide plate system engineered for racers and serious performance enthusiasts who demand precise, progressive power delivery. Where a single-stage system can overwhelm traction with an immediate power spike, the Dual Stage Big Shot splits power delivery into two distinct, controlled events — giving drivers the ability to carefully manage weight transfer, tire grip, and overall track performance.

Two-Stage Power Delivery:

• Controlled launch boost: The first stage is activated by a throttle-actuated micro-switch, delivering a moderate initial power boost to get the vehicle off the line cleanly without overwhelming available traction
• Full-power follow-through: Once the tires are hooked up, the driver activates the second stage via push-button switch — which automatically deactivates the first stage — for a powerful, sustained surge through mid-track and beyond
• Precision solenoid architecture: Two Cheater solenoids govern the first stage, while a Super Pro Shot nitrous solenoid and a high-output Cheater fuel solenoid command the second stage for accurate, repeatable fuel and nitrous metering
• Adjustable horsepower output: Power output is fully tunable by swapping included fuel and nitrous jets across a wide range of horsepower targets without additional hardware
• Special fogging plate design: The Big Shot platform uses a purpose-built fogging injector plate that delivers a finely atomized nitrous and fuel charge for consistent, even cylinder distribution
• Optional electronic controller compatibility: Pairs with a NOS Progressive Nitrous Controller to dial in exact nitrous delivery percentages and fine-tune activation timing for maximum consistency
• Complete hardware included: Each system ships with a fogging injector plate, solenoids, filters, fuel and nitrous fittings, power jets, switches, aircraft-quality stainless-steel braided hose, and all required installation hardware

Built for Competition-Prepared Engines:

The Big Shot platform is engineered for extensively modified, competition-ready engines. These systems generate elevated cylinder pressures that significantly increase stress on internal engine components — making thorough engine preparation and a compatible high-flow fuel system essential prerequisites for safe, reliable operation.

Nitrous Oxide Systems (NOS) is the most trusted name in nitrous performance, having powered more winning race vehicles than any other nitrous brand. The Dual Stage Big Shot line is available in multiple configurations to suit different carburetor flange styles and horsepower targets, with variants offered with or without nitrous bottle.
