Add Water-Methanol Injection to your Volkswagen 1.9L/2.0L TDI if you're looking for more power, efficiency, and lower EGT's. Typically blended at a 50/50 ratio Water-Methanol provides maximum cooling and gains in power and efficiency. Water-Methanol cannot simply be sprayed at any time, there must be a certain level of boost and heat already built up before it can be injected. Water-Methanol systems require heat and boost in order to instantly vaporize the water into steam, thus preventing potential damage from water being injected into the engine. Water-Methanol Systems cannot operate in low RPM and low boost situations as the water will not vaporize into steam. Water-Methanol Systems operate by injecting a high-pressure mixture of water and methanol into the intake of the engine.
Water-Methanol Systems function by using water to cool the intake and exhaust temps and increase the efficiency of combustion. Due to the nature of how Water-Methanol works, the systems will not be very beneficial for vehicles that are driven lightly or simply cruise on the freeway. Water-Methanol Systems benefit the engine by cooling the intake and exhaust air temps as well as providing more efficient combustion from the added methanol. Water-Methanol mixtures can be purchased already blended and ready to pour in, or it is a common practice to make your own mixture using water and windshield washer fluid that contains methanol. Systems manufactured by Snow Performance and Banks Power are some of the more popular Water-Methanol kits available for your diesel truck.
