The Bosphorus Innovations Stage 1.5 Turbo Diesel Water/Methanol Injection Kit is an advanced all-in-one system combining a digital boost gauge, progressive water-methanol controller, and built-in fail-safe architecture. Equipped with an integrated 10 bar (145 psi) MAP sensor and a striking dual-tone white/red LCD display, it provides precise, customizable fluid delivery to drastically lower intake temperatures and eliminate engine knock.
Integrated 10 Bar MAP Sensor: Features a built-in 10 bar / 145 psi absolute pressure sensor allowing fully adjustable boost-dependent injection mapping.
Advanced Dual-Tone LCD Display: High-visibility white/red screen displays real-time boost pressure, injection status, fault codes, test modes, and custom adjustments.
Pulsation-Free High-Pressure Pump: Utilizes an internal bypass design instead of a pressure switch for a smooth, constant, and even spray pattern.
Large 5.9L Fluid Reservoir: Includes a generous 5.9-liter plastic tank to ensure a steady, reliable supply of water-methanol mixture during heavy driving sessions.
Engineered for serious performance builds, the Stage 1.5 Water/Methanol Injection Controller merges multiple standalone devices into a single, compact, high-precision unit. By spraying a fine water-methanol mist into the intake under boost, the system effectively reduces manifold air temperatures and exhaust gas temperatures (EGT) to protect pistons from thermal fatigue while increasing your effective octane rating.
Smart Control & Customization The built-in digital controller lets you tailor your injection curve precisely to your engine’s requirements. With features like adjustable start points, fine-tuning resolution, response time adjustments, key lock, and a built-in fail-safe system, you maintain total command over your forced induction setup. Furthermore, all metal components are manufactured from corrosion-resistant nickel-plated brass, standard brass, and EPDM-grade plastics certified for 100% methanol durability.
Key Benefits & Features
Combustion Efficiency: Enhances dynamic compression, optimizes burn efficiency, and reduces harmful emissions (CO, CO2, NOx, and HC).
