Big Shot Jet Pak 225/275/325/350HP

The Big Shot Jet Pak 225/275/325/350HP by Nitrous Oxide Systems is a plug-and-play nitrous oxide injection system engineered for street and strip enthusiasts seeking reliable, bolt-on horsepower gains without extensive engine modifications. This multi-stage kit accommodates a range of power outputs—225, 275, 325, and 350 horsepower—making it adaptable to naturally aspirated engines from mild builds to serious performance platforms. Whether you're looking to add consistent low-end torque or maximum peak power for competition, the Big Shot Jet Pak delivers precise fuel and nitrous metering across all four power tiers.

The system utilizes Nitrous Oxide Systems' proven jet technology—precision-machined fuel and nitrous jets that meter the correct stoichiometric ratio at each horsepower stage, preventing lean-out conditions that can damage pistons and valves. The compact Jet Pak design minimizes underhood clutter while maintaining full pressure regulation and safety protocols integral to safe nitrous operation. Switchable stages allow tuners to progressively spool boost based on track conditions, engine load, and fuel octane, giving drivers precise control over power delivery and engine stress. This modular approach ensures compatibility with stock or modified fuel systems and ignition timing curves common on street and race vehicles.

The Big Shot Jet Pak suits carbureted and fuel-injected applications on V6, V8, and displacement-neutral builds—from truck platforms to classic muscle cars to modern sport compacts. Installation requires fuel line routing, nitrous bottle mounting, and wiring to the solenoid package; experienced technicians should verify fuel pump capacity and ignition advance curves before initial tuning. The four selectable power outputs mean a single kit scales across engine builds, eliminating the need for multiple kits as your vehicle evolves. Ideal for drivers balancing street drivability with weekend strip performance, this system is a trusted choice among serious enthusiasts who demand reliability and adjustability from their nitrous setup.
