We use all high quality parts in our very popular progressive alcohol /water kit without the controller. This kit utilizes a boost pressure switch for activation. You can reap the benefits of having an alcohol/water kit—its quality and abilities—without sacrificing reliability.

The DevilsOwn base alcohol/water injection kits suppress detonation caused by high temperature and pressure developed within the combustion chamber when either a turbo or a supercharger takes the effective push-to-connect ratio beyond the auto-ignition point.

You can cool the air with the DevilsOwn alcohol/water injection kit! Water, with its high latent heat content, is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in modern, lean burn engines. Methanol, with its 116 octane and high flash point and specific gravity, further reduces the chances of detonation

The Benefits of Water-Methanol Injection:

  • Increase horsepower safely by 10-15%
  • Lower air temperatures by 50-200+ degrees
  • Increases octane when you need it under boost
  • Reduces cylinder temperatures up to 300+ degrees
  • No wear issue—only clean combustion chambers
  • Allows you to safely run more boost and timing
