Description

Unlike systems with complex controllers, this kit employs an automatic boost pressure switch to manage the injection of water-methanol. This mechanism ensures that injection occurs when boost pressure rises and ceases when it drops below the set point. The primary function of water-methanol injection is to combat detonation, a phenomenon stemming from excessive combustion chamber temperatures and pressures. By injecting a water-methanol mixture, the system actively cools the charge, increases the effective octane rating of the fuel, and reduces cylinder temperatures. This not only prevents power loss associated with detonation but also offers benefits such as lower Exhaust Gas Temperatures (EGTs) and a cleaning effect on fuel deposits. This comprehensive kit includes all necessary components for installation: an automatic boost pressure switch, a 300 psi pump with EPDM seals, a heavy-duty nickel-plated check valve, 15 feet of high-pressure nylon tubing, two micro-droplet nozzles (D03 and D07), a filtered self-sealing tank tap, and all required hardware. Detailed instructions are also provided. The system is designed to run effectively with a 50/50 mix of distilled water and methanol, or solely on distilled water for its cooling and cleaning properties, though power gains may vary. Water-methanol injection is recommended for those seeking to increase horsepower, improve fuel mileage, or enhance engine longevity. It functions as a power modification that, contrary to some other upgrades, actually reduces strain on the engine while enabling performance gains. The kit comes with a 1-year warranty against manufacturer defects.

MIA's Description

The DevilsOwn Stage 1 is a complete water methanol injection kit designed for already boosted vehicles. It utilizes an automatic boost pressure switch to control injection timing and amount. The kit suppresses detonation caused by high temperatures and pressures in the combustion chamber, aiding in reducing power loss.
