NOS Super Powershot Nitrous Oxide Injection System

The NOS Super Powershot is a complete, carburetor-compatible wet nitrous oxide injection system engineered to deliver immediate, on-demand horsepower gains for serious street and strip performance. Built by Nitrous Oxide Systems (NOS) — the original and most trusted name in automotive nitrous injection — the Super Powershot line brings decades of race-proven engineering to a bolt-on platform that's accessible to builders at every level.

Wet System Technology

The Super Powershot uses a wet-system design, simultaneously delivering both nitrous oxide and supplemental fuel through precision-machined spray bars integrated into a low-profile injector plate. This dual-injection method creates a smooth, controlled surge of additional power without disrupting idle quality or everyday drivability, making it equally capable on a dedicated drag car or a high-performance street machine.

Key Features:

• Adjustable power output — Replaceable flare-style jets allow tuning across multiple horsepower levels simply by swapping jets, with no additional hardware required
• Dedicated NOS PowerShot solenoids — Separate nitrous and fuel solenoids provide precise metering and reliable, repeatable activation
• Microswitch activation — Wide-open-throttle engagement delivers consistent, predictable power every pass
• Low-profile injector plate — Thin plate design sandwiches between the intake manifold and carburetor with minimal modification to the existing engine setup
• Complete kit contents — Systems include a nitrous bottle with mounting brackets, nitrous and fuel solenoids, injector plate, stainless braided fuel line, fittings, replaceable jets, all necessary mounting hardware, and comprehensive installation instructions
• Fuel economy unaffected — Nitrous injection is only active at full throttle, leaving normal cruising and part-throttle operation completely unchanged

The NOS Legacy

NOS pioneered the development of automotive nitrous injection systems, and its products have powered more racers than any other nitrous brand. Milestones including the first 200 mph and first 6-second drag passes in the Pro Mod class were achieved with NOS assistance — a heritage that continues to drive every product in the lineup today. As part of the Holley Performance family of brands, NOS Super Powershot systems are manufactured to the exacting quality standards that professional competitors and weekend racers alike have relied on for decades.
