NOS Dual Shot Cheater Two-Stage Wet Plate Nitrous System

The NOS Dual Shot Cheater™ Nitrous System is a complete, two-stage wet plate nitrous oxide system purpose-built for carbureted racing applications where traction management and consistent power delivery are critical. Engineered around the principle that staged power wins races, each system in this product line functions as two fully capable nitrous systems combined into one comprehensive kit — delivering adjustable, independently tunable performance from the moment the throttle opens all the way through the finish line.

Two-Stage Power Delivery:

• Stage 1 activates automatically via a throttle-mounted microswitch, delivering an adjustable power boost in the 100–150 hp range to keep the car hooked up and planted off the line
• Stage 2 engages on driver demand via a push-button switch, adding a second independently tunable power hit of 150–250 hp once full traction is established
• Both stages are individually adjustable through quick jet changes, allowing real-time tuning for shifting track and weather conditions — accomplished in a matter of seconds
• An optional delay timer (NOS PN 15838NOS, sold separately) can be integrated with the second stage for maximum lap-to-lap consistency
• An included variety of power jets enables total output to be dialed back to as low as 50 hp for conservative tuning or entry-level setups

Premium Components Included:

• Two Super Powershot™ solenoids for high-volume, reliable first-stage nitrous delivery
• Two Cheater™ solenoids engineered for robust second-stage performance
• A low-profile ½" injector plate designed to fit between the carburetor and intake manifold with ample hood clearance
• Aircraft-quality steel braided hose for durability and safety under demanding race conditions
• Filters, fittings, and a comprehensive variety of power jets for broad tunability across multiple power levels
• Complete electrical components, switches, and all necessary mounting hardware for a full bolt-in installation

Proven Wet Plate Technology:

Every kit in this product line is built around NOS's proven wet plate injection design, which delivers both nitrous oxide and supplemental fuel simultaneously through a thin injector plate, ensuring efficient and uniform distribution across all cylinders. Installation requires only basic hand tools, and the comprehensive hardware package ensures a complete, ready-to-race setup. Racing fuel is recommended at higher power output levels. For best results, a single-plane intake manifold should be used.

Compatible with NOS Accessories:

• NOS Progressive Nitrous Controllers are available separately and fully compatible for even finer power ramp-up control — ideal when staged activation alone is not sufficient
• Optional Precision Delay Timer (NOS 15838NOS) available for second-stage tuning precision and improved 60-foot and quarter-mile consistency

Important Notes:

• Intended for off-road and racing use only — not legal for use on emissions-controlled or street-driven vehicles
• Not recommended for intake manifolds with a separate inlet for each carburetor throttle bore, except for 3×2-barrel setups
• Individual variants are available to match specific carburetor flange configurations — select the appropriate listing for your application
