The Bosphorus Innovations Stage 1 NA Water/Methanol Injection Kit is engineered specifically for naturally aspirated (NA) engines. Triggered by a Wide Open Throttle (WOT) switch, it delivers a smooth, constant fluid flow without pressure pulsation to optimize combustion efficiency, eliminate engine knock, and increase dynamic compression.
WOT Activated Setup: Automatically deploys injection precisely when wide-open throttle is engaged.
Pulsation-Free Pump Design: Employs an internal bypass architecture instead of a pressure cut-off switch for a perfectly smooth, constant spray.
Massive HP Support: Standard pump handles up to 1000 HP (up to 1260 ml/min or 20 GPH).
Complete Kit Infrastructure: Includes a 3-liter HDPE tank, controller, wiring harness, and a wide selection of nozzle flow rates.
Designed to maximize performance in naturally aspirated (NA) engines, the Stage 1 NA Water/Methanol Injection Kit introduces precise fluid delivery under full throttle. By spraying a water-methanol mixture into the intake stream, the system significantly lowers intake air temperatures (IAT) and exhaust gas temperatures (EGT), protecting pistons from thermal fatigue while boosting effective octane ratings to stop destructive engine knock.
Advanced Pump & Flow Technology Unlike conventional systems, our high-pressure diaphragm pump features an internal bypass mechanism rather than a traditional pressure cut-off switch. This eliminates fluid pulsation and delivers a continuous, perfectly even spray pattern through the nozzle. Built from corrosion-resistant components—including nickel-plated brass, standard brass, and EPDM plastics—the entire hardware chain is completely safe for methyl alcohol and water.
Key Benefits & Features
Thermal Protection & Power: Lowers manifold temperatures and EGT to prevent piston damage while raising combustion efficiency.
Knock Suppression: Safely increases total effective octane to eliminate pre-ignition and engine knock.
Emissions Reduction: Lowers carbon monoxide (CO), carbon dioxide (CO2), NOx, and hydrocarbon (HC) output.
Customizable Nozzle Selection: Tailor your flow rate based on your exact engine setup (available in sizes ranging from 95 cc up to 2200 cc / 35 GPH). Default configuration is 252 ml/min (4 GPH) with a Red Hose if no preference is specified.
Nozzle Selection Guide
