Originally, it was used to reduce knock while increasing power and performance in aircraft engines. Eventually it came to be used in the motorsports industry where it was found to have substantial benefits on turbocharged engines. The Weistec Water-Methanol Injection System provides substantial cooling and knock prevention benefits to the S63TU engine helping improve consistency and performance.  The system features a Water\/Methanol Controller with built in MAP sensor.  This controller is a progressive controller that slowly increases injection as boost builds, resulting in smooth and seemless operation.  To tap into the manifold for vacuum and boost readings, the custom designed and CNC machined billet aluminum Weistec Vacuum\/Boost Adapter is included, simplifying boost reference installation.  The included Weistec Silicone Turbo Charge Pipes each have a built in port for the Weistec Barbed Injector Body, allowing the use of two injectors for uniform injection and cooling.  The combination of the cooling effects of methanol and the knock resistance of water result in significant gains(through improved cooling and octane) in horsepower* and torque* as well as reduced chance of heat soaking the intercooler system.\u003c\/p\u003e\u003cdiv class=\"videoWrapper\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/g2Q4uHGmr6g?enablejsapi=1\u0026amp;version=3\u0026amp;rel=0\u0026amp;controls=1\u0026amp;playerapiid=ytplayer\u0026amp;modestbranding=1\u0026amp;autohide=1;fs=1\u0026amp;\" frameborder=\"0\" allowfullscreen=\"\" width=\"862\" height=\"519\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\u003cp\u003eThis system is a complete, bolt on system that can be installed with out any guess work or custom fabrication.  Weistec has engineered and manufactured many of the components of this system to ensure a simple and straight forward installation that a universal kit simply lacks.
