How BMW Used Water To Make +50 Horsepower

How Water Injections Systems Can Create More Horsepower A Detailed Explanation Of BMW’s M4 GTS Water Injection Engine Subscribe for new videos every Wednesday! - EE Shirts! - Recommended Books & Car Products - The BMW M4 GTS is one of very few production cars to ever be fitted with a water injection system, used to take the twin-turbo I6 engine from 444 Horsepower up to 493 horsepower, using the beauty of evaporating water to do so! From BMW, here’s how it all works: “Water is injected as a fine spray into the intake manifold plenum chamber where it evaporates, significantly lowering the temperature of the intake air. This reduces the final compression temperature in the combustion chamber, which also reduces the risk of knock, allowing the turbocharged engine to operate with higher boost pressure and earlier spark timing. The result is increased power and torque, and a substantial imp
