Vapor Injection

Water is free, so for this calculation we will assume that you are using some methanol, for a cost of roughly $2 per gallon for your water/alcohol mixture. We will also assume that 1 gallon lasts for 3 tanks of gas (many people get more, many people get less, so 3 tanks is about average). If your gas tank holds 15 gallons, then that $2 for the methanol is spread out over 45 gallons of gas, for a cost of 4.5¢ per gallon.

The difference in cost between 87 octane and premium fuel, averages about $0.30 per gallon.

So if you can use 87 octane with Water/Alcohol Injection, then you will save approximately $0.25 per gallon of gas. The average driver drives at least 1000 miles per month, getting 20 miles per gallon. This means that the average user buys 50 gallons of gas per month. At a savings of $0.25 per gallon, that equals $12.50 saved per month. Over the course of a year, this equals $150, just under the price of our introductory kit.

Those numbers are based on low miles per month, at a relatively good miles per gallon average. If you drive 1500 miles per month, at 17 miles per gallon, your monthly savings are $22, and your yearly savings are $264!

Engine modifications: The DevilsOwn™ Alcohol System, out of the box, is designed to work as a bolt-on kit for stock or mildly modified vehicles. Mildly modified vehicles would include header upgrades, exhaust upgrades, air filter kits, etc. If major engine modifications have been performed a dual nozzle upgrade may be required for safe alcohol system operation.

Major engine modifications would include larger turbochargers, superchargers, aftermarket cylinder heads, head porting, camshafts, intake manifolds, etc. Failure to upgrade highly modified applications may cause serious lean conditions that can result in severe engine damage.

Vapor Injection Questions

Brief History

Water injection was evaluated scientifically in the 1930.s by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol.

The first widespread use was during WWII on supercharged and turbocharged aircraft. In 1942, the German Luftwaffe increased the horsepower of the Focke-Wulf 190D-9 fighter aircraft from 1776HP to 2240HP using 50/50% water/methanol injection.

The allies soon followed by fitting the P51 Mustang and other high performance aircraft with water/methanol injection. Following the war, the turboprop aircraft industry used water/methanol injection and called it the "automatic power reserve system (APR)" for use in hot or high altitude take off.

It surfaced again in the 60's when GM used a system on the OEM turbo Corvair. It was used effectively in Formula 1 before being banned for adding too much power.

Applications

Click Here>>>>>> In gasoline engines, as with any inter-cooler, this suppresses detonation so more power producing boost and timing can be utilized. Water, with its high latent heat of vaporization cools the intake charge and combustion. Methanol cools the charge and combustion but also acts like an extremely high octane fuel (some researchers claim as high as 120 octane) as well as adding more oxygen to combustion.

Click Here>>>>>> In diesels engines, the effect is three fold: 1. The inter-cooling effect provides for more available air and all the benefits of a higher positive pressure ratio (more power giving fuel can be utilized safely without high combustion temperatures).

2. The combustion of water provides for more power on the power stroke.

3. Methanol acts as an additional fuel for more power.
