The Bosphorus Innovations Stage 2.5+ Dual-Stage Water/Methanol Injection Kit is the ultimate high-capacity system engineered for ultra-high-horsepower builds. Combining an advanced dual-stage digital controller with a built-in 10 bar (145 psi) MAP sensor, dual fast-reacting solenoids, and premium chemical-resistant PTFE Teflon hosing, it delivers precise, multi-stage fluid delivery to eliminate heat soak and protect heavily boosted engines.
Dual-Stage Progressive Control: Manages dual injection points independently for seamless, ultra-precise fluid delivery across wide power bands.
Integrated 10 Bar MAP Sensor & LCD: Built-in absolute pressure sensor paired with a high-visibility white/red dual-tone screen for real-time monitoring and tuning.
Dual Solenoid Safety Protection: Features two fast-reacting solenoids to eliminate gravity siphoning and ensure 100% safety for complex or rear-mounted setups.
Premium PTFE Teflon Tubing & 5.9L Tank: Upgraded with durable PTFE Teflon hosing and a generous 5.9-liter fluid reservoir to handle extreme methanol concentrations and flow rates.
Bosphorus Innovations Stage 2.5+ Dual-Stage Water/Methanol Injection Kit (MAP, Dual Solenoids & PTFE Hosing)
Designed for professional motorsport applications and extreme forced-induction builds exceeding standard limits, the Stage 2.5+ Dual-Stage system merges a digital boost gauge, progressive multi-stage controller, and fail-safe architecture into one powerful unit. By utilizing two independent injection stages controlled via an integrated 10 bar MAP sensor, the system saturates the intake tract precisely when your engine demands maximum thermal suppression.
Uncompromising Durability & Flow Equipped with a pulsation-free high-pressure pump (supporting up to 1000+ HP), this kit features 100% methanol-resistant nickel-plated brass, standard brass, EPDM-grade plastics, and upgraded PTFE Teflon hosing for maximum chemical resistance under high pressure. Dual fast-reacting solenoids lock fluid in place when idle, ensuring absolute safety across all mounting configurations.
Key Benefits & Features
Extreme Thermal Protection: Dramatically lowers intake manifold temperatures and exhaust gas temperatures (EGT) to prevent piston melting.
Knock Suppression & Power: Increases effective octane ratings to eliminate destructive detonation, allowing higher boost and aggressive timing.
Emissions & Efficiency: Enhances dynamic compression and combustion efficiency while reducing harmful CO, CO2, NOx, and HC emissions.
Complete Professional Package: Includes a 5.9-liter plastic tank, dual nozzles, dual 40-micron stainless steel filters, dual check/solenoid valves, complete wiring harnesses, and a 2-year warranty.
Nozzle Selection Guide
100% Water: 10–15% Water-to-Fuel ratio or 0.5–1 cc per HP
50% Water / 50% Methanol: 15–20% Mixture-to-Fuel ratio or 1–1.5 cc per HP
100% Methanol: 20–25% Methanol-to-Fuel ratio or 1.5–2 cc per HP
(Default configuration: 252 ml/min [4 GPH] nozzles and PTFE Teflon tubing if no specific size/color is indicated before ordering).
