Water Gas Injector

Saves 3-5+ MPG
For only $75.00!

During WWII there was not enough gasoline. Water vapor injection and water injection were developed after it was discovered that combustion of less than micron sized water particles - when added to gasoline in small amounts - increased engine power, performance, and flight time (MPG) in fighter planes.

Legend has it fractional addition of water vapor and water injection techniques were developed after fighter pilots noticed that mileage and engine performance improved when they flew their planes close to the water. It became standard practice for pilots to "lean out their engines" (decrease the gasoline) and fly just above the water on the critical return trip to the carrier. They knew that if they did not stretch every drop of fuel they had they would not make it back.

This Watergas Injector is based on an original WWII design that we found and used extensively, in Buffalo, New York, during the 60's. Over a three year period, we tested the Watergas Injector pictured to the left on three different vehicles and achieved an average increase of 3-5 MPG. At that time, we also documented decreases in tail pipe emissions* as well as power and performance improvements.

The bubbling action of the Watergas Injector reduces water to less than micron sized particles of water vapor. The engine vacuum is employed to draw a small amount (less than .025%) of water vapor into the engine manifold where it mixes with the gasoline (called fractional addition) providing complete combustion, better performance and improved mileage.
