Default Alcohol Injection Nozzle selector tool

Alcohol Nozzle size Calculator
This should give you an idea what size nozzle you need with all the alcohol Injection kits out there. Even an DIY kit. This is still kinda a beta on the figures so if anyone could give me feed back I would greatly appreciate it.

thanks, I plan to add more options for blower/turbo efffecy etc. Thats why i do have the assumed cfm listed and the assumed btu. It can only do so much when it does not know actually Ait and cfm. I did not want to run this off injector size, like another one of these i saw floating around. because what stops someone from shoving injectors to large for the app. You start getting into high hp per cubic inch and this gets off.

Pretty cool, but I'm lost as to how it comes up with the required flow when there's no input for injection to petrol % and max pump pressure.

peace

Hippy, We use a custom made pump, we wanted this to be generic "useable" between other systems. 1 gallon of fluid at 1,000 psi is still 1 gallon of fluid. So people need to be aware of what pump they plan on using when using this. And what the nozzles is rated at for that given psi. Also nozzle size will effect pressure. And most people don't understand this. So I did not put our pumps flow data into it. So that number is the amount of fluid needed. I probley should re word it to make it more clear.

Also this does not take into effect adding extra fuel with the meth kit. This is the amount of fluid need to remove the assumed heat thats being generated by compression of the air. Now some compressers are more effecent than others. this atm is not a varable, Which will be latter. I need people to email me the stats so i can plug them in my db.

I understand what you're sayin about pressure, and I agree. I don't agree about injection percent, and this is why. Not everyone wants to run the amount of injection you think they should run, and people who run run 5% water to fuel will want a nozzle that flows about a third of the water of a nozzle that someone who has the same setup and runs 15% water to fuel would want. Your little device has a build in figure that assumes everyone wants to run the same injection to petrol percent, and this is not the case. This value needs to be adjustable for people to be able to pick a given nozzle for a given setup and tune.

peace

I'll get right on that since I am a software programmer and know exactly how to do that. For what it's worth, your post is the most useful thing I've seen anyone post in years. Thanks for all your time and consideration when thinking about what to post and the way you explain yourself. Whenever I need help, I'm gonna send you an e-mail so you can tell me what to do.

How about a percent alcohol to water feature? I would think water only would require less than 50/50 which would be less than 100% alcohol.

Does yours assume 100% alcohol?

Im not a software programer, I had the caculations just getting it into the exe and it looking good was not easy for me. I do plan to make some changes to this.
klatery this assumes a 50/50 mix. Its not going to make the world of differnce between straight water and straight meth, because this is only giving you a value for geting your ait down. With runing higher amounts of meth you can run a larger nozzle especially when you pull fuel. Any ohter questions let me know.
