Devils Own High Boost Stage 1


All the high quality parts as our very

popular progressive alcohol /water

kit without the controller. This kit utilizes

a boost pressure switch for activation.




We use only high quality parts, just as we do 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 with quality and ability, but without sacrificing reliability.

The main function of the DevilsOwn Diesel Base water/alcohol injection kit is to suppress detonation caused by high temperature and pressure developed within the combustion chamber when the effective push-to-connect ratio has been taken beyond the auto-ignition point by either a turbo or a supercharger.

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 the 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
