I have one I bought gears ago. Its a very nice system put's the water into the top of the carb.
It has a electronic control that you can adjust the water by vacuum, RPM. as to when and how much water.
I have never used it but plan on putting on a dual 4 V

FE 427: If you don't mind can you show pic's of what you have? I am thinking along this line with what you have...I am curious to see if I can modify mine, so that I can have vacuum at the base of the carb for in town driving, then for Highway driving, have something like yours..I already drilled my air cleaner top and have a fitting and hose in place..I need to find a jet size that is small enough to mist water and a big enough pump with at least 100# pressure to vaporize the water out of the jet...perhaps a solenoid to activate when pedal to the metal, or something similar...

Recently, I added to my 750cfm Holley an adjust a jet from Percy's...I pulled out my 70 jets and installed the new metering block in front of the Holley metering block...So, I am curious how close this jet size would work with a 100# water pump and solenoid switch backing this jet at the top of the carb somewhere...
Thanks for your input~!

Are you guys using water injection at part throttle cruising?

Yes, I posted a design at the start of the thread from Mother Earth News from back in the late 70's...If you do the search for Ron Novack's water injection, or just click the link I have at the beginning, you will see the plans and what I am currently using...I think I have about $20.00 into it... It does work~!

I will measure the jet tomorrow and let you know.
I read this forum a lot but this is the first time I have posted
If I can figure out to post pic. I will send you the manual
This unit uses a ford windshield washer that has the pump
in the bottom so a floor switch should work perfect.

I go through Photo bucket to post pictures...just start an account and that will allow you to post pictures here...takes a little bit to figure it out..I use to windows to copy and past using the icon right above the enhanced mode as you type ur reply like I am doing right now..It is the one that has the blue ball and chain to post pictures...

I didn't get the unit down it's in the Attic of the garage but got a copy of the manual in my filing cabinet , looked at it but gave no measurement's, the jet is a tube with groves for the hose on one end the other is pointed with a jet hole on each side to
discharge into both pri. vent.
If you will give me your E-mail add. or I will send you mine
and I can send you a nice large copy

I'll PM you with my email address...Thanks

so im thinking of running this in my 302 ford engine. will i have to advance my timing for sure? and also could'nt the increase in compression blow a head gasket? and anyone know where the proper vacuum line is on a general 2 barrel?

sorry I know I am asking a lot of Q's, but I'm looking to get any power/mpg gain I can!

There's no reason to advance your timing when you add a methanol injection system. It's designed to simply keep your engine from pinging under load at normal timing with higher compression engines.
There;s also no reason to run straight methanol. The instructions with mine said to use a water/methanol mix, and the percentage of methanol wont cause any compression issues.
Your vacuum connection should be a port in the carb's base plate where your vacuum hose for distributor vacuum advance hooks to. Simply put a T in the line to hook in the system.

It is my understanding that you do not NEED the methanol. It is there to prevent the water from freezing during the Winter months.

[1971BB427]

Yes, the methanol does deter freezing, and the more you use the less chance to freeze up. It also evaporates quicker the more you use, so putting more in just means you'll need to add more sooner. The reservoirs are not sealed, so it happens.
My system uses so little fluid that I usually find it dries out long before I use it up. My system instructions said to use premixed windshield washer fluid for the perfect mixture of water/methanol.

[allclassicsbefore70]

Cool, sounds good. Yeah since the weather reports say it has officially never frozen where I live in socal, I think i will run all water with a couple drops of winshield wiper fluid. And what about the bubbler? do i need one if I am using straight water? and the nozzle is it a special part or generic? any links to that one...

thanks again you guys rock.

[1971BB427]

Never heard of bubbler for this system, and nozzles are part of the kit. Mine came with several, plus ability to select the water/methanol shot depending on your engine.

[allclassicsbefore70]

Yeah I would prefer building my own I enjoy those kinds of projects. Oh ok so let me get this straight, the atomizing nozzle end that sprays faces towards the carb, and has a tube submerged in the bottle of water to supply the nozzle with water?
