  1. How does alcohol/water injection work?
  2. By injecting a fine spray of alcohol/water into the inlet air stream of the engine, the charge air is dramatically cooled and the effective octane of the fuel is raised. Both help to eliminate detonation — the enemy of any engine, especially those using today's lower octane fuel under boost.

  3. Can alcohol/water injection damage my motor?
  4. Not if installed and used properly. As long as the injection system is working properly, it can only do good things. Since the alcohol will dissolve carbon buildup, It will help keep your plugs, valves, and combustion chambers very clean.

  5. My turbo/supercharged engine runs standard boost, would alcohol/water injection increase the horsepower?
  6. Alcohol/water injection will not increase the power usually. However, in areas where the ambient temperature is very high, injecting alcohol/water mixture will lower the inlet charge temperature and this will help produce a power increase.

  7. Do your kits come with a tank?
  8. All of our kits ship without a tank, but include the fittings to convert your existing washer tank for use with our system. Additional tanks can, however, be purchased separately here on this site. We want to let you have the options of what size tank if you need one.

  9. I would like to increase my power output by increasing the boost pressure. Would alcohol/water injection help then?
  10. It all depends, if you have good quality fuel and the ambient temperature is not too high you can normally get away with 2-3 psi of boost increase without using alcohol/water injection and will not run into detonation problems. On the other hand, if you DO NOT have good quality fuel, the ambient temperature is high, or there is a slight tendency for engine knock, then alcohol/water injection or a bigger intercooler is essential.

  11. How much alcohol/water do I need spray?
  12. Most cars should aim for 15% of their total fuel flow. Some more extreme setups run as much as 25% of their total fuel flow.

  13. What kit should I get, Stage 1 or Stage 2?
  14. Our DevilsOwn Stage 1 "Base" injection kit incorporates a boost switch that activates the system at a specific PSI. It’s adjustable from 2-10 psi or 6-30psi, but you can run up to 250 PSI through the switch, so it’s very reliable. This system will turn on at a level you set and stay on until you drop below that level. It’s On/Off. It can’t dial in exact flow, but it can get you within a range.

    DevilsOwn Stage 2 "Progressive" kits offer high functionality and performance, the ability to vary the flow based on inputs (maf, map, tps, ait, any 0-5v source). Most users run it off of separate GM style map sensor if there car does not already have a map sensor. With the Stage 2 Kit you set a starting boost and a full boost and the system will progressively adjust the flow between those two points.

    Both styles work. We tell our customers that if budget is the primary concern, get the base injection kit. If you have a little more money to spend or want something with more user control, the progressive kit is worth it.

  15. What liquid should i run in this system?
  16. We recommend DevilsOwn Brew, our proprietary methanol blend. Not only does methanol improve your fuel quality, it will also give you a better intercooling effect in the inlet tract.

    Denatured alcohol can be used but we strongly advise our customers to use methanol for better, more consistent performance.

  17. What is the maximum alcohol/water ratio your system can handle?
  18. The wetted components in the pump head are chemically compatible with 100% methanol. The motor of this pump is not CLASS I explosion proof and therefore the pump is not compatible with 100% methanol. The rest of the components are engineered to withstand 100% methanol for the normal expected life of the product. We recommend using DevilsOwn Brew, our proprietary methanol blend, to reduce the risk of fire and improve consistency and performance.

  19. Does the water "burn" in the engine?
  20. No. The water simply converts from a vapor to a gaseous state which absorbs huge amounts of heat, due to the energy required to transform it.

  21. What supporting upgrades are required for alcohol/water injection?
  22. At minimum, your vehicle should have some sort of engine management that can be tuned, for example, the ability to adjust timing, boost, and fuel curves to compensate for the octane boost and cooling effects, and the ability to take advantage of the adjustments to make power.

    You can run alcohol/water injection on a stock car with tunable engine management. It is not necessary to have after-market intakes, exhausts, intercoolers, or strengthened internals. However, with supporting mods that already increase the volumetric efficiency of the engine, more power can be made.

  23. Why not use a windshield washer pump?
  24. Alcohol/water must be injected at above 50psi to properly atomize. Pressure lower than 50psi causes greatly reduced air charge cooling as the result of larger droplets and their reduced total surface area.
