For those wondering, Here's how it works. Torque is what moves a vehicle, Not horsepower. Hydroxy gas increases cylinder pressure, flame speed, shortens burn time, increases thermal efficiency, and allows for a "Lean Burn" situation. -Increase cylinder pressure = more mpg. -Increased cylinder pressure at low rpm = more mpg. -Increase flame speed increases cylinder pressure = more mpg.-Shorter burn time means less heat transfer means more mechanical power= more mpg. Hydroxy Gas allows you to Lean Out the air/fuel mix so the HHO can supplement the lack of Fossil Fuel to increase MPG. - HHO Gas burns 10x faster and cleaner than gasoline or diesel fuel.
