Devilsown water-alcohol injection Nozzle size calculator.
This is what we have been using for you guys who call us or email us wanting to know. What size nozzle does my car need. This is our first release of this software and fort he most part its accurate for gasoline engines. Diesel engines are still way off. We will update this as we get feed back. If you see anything that out of the norm let me know. Hit the save to button and email us the file to Support@alcohol-injection.com Or post it this forum. More feed back we get the more accurate it will get. We do plan on adding more inputs for so we can guesstimate hp to make it more accurate on Hp for cubic inch engines. And for larger engines.

This is the most accurate nozzle calculator out there. Which we plan to impove with your help. Fell free to pass this file around.

for rotary engine applications should we use 2.6L then?

that is generally how we do things..

[Rocket468]

yea, rotary guys should double there Litters. Can you post up your results, or email them to me with your mods so i can double check things. This is beta still and its hard to have a 1 size fits all.

On mine, there was a number stamped into the side of the nozzle. I believe this indicates the size.

The calculator says I need a 4.1 ghp nozzle but I have a 5. What should I do? Is it best to go larger or go down to the 3? I have drive VR6 with a t3/t4 at 10 psi non-ic.
