It is far cheaper to use windshield washer fluid.

Water Vapor Injection + HHO Booster

On water vapor injection only, I tested approx 2600 miles on my civic and I got max 45mpg average on a good driving day. I combined a simple HHO booster + vapor injection, now I am getting 50+mpg average consistently for more almost two months now.

The HHO booster I used is based on this design http://www.greenfuelbooster.com/refe...entations.html

I have tried both systems, but not at the same time. Has anyone heard any credible evidence that would support the claim that WI is just as good as HHO?

Thumbs up CArburetror cars & trucks

I have built several HHO boosters. On a 2000 taurus I get great hp and a little less mpg. I finally went to an evaporative system. Same results. I putchased a 1983 Dodge Rampage 2 brl carb 4 cylinder. I put the evap on it and got a 31% increase in mpg. 22 mpg to start and now 29 mpg. I do not inject water. All my vehicles I have an evap on draws a fumes of water I connect to the intake manifold and let the vacuum draw the wter molecules into the engine. The system is sealed to outside air and has only on hose connecting it. No air travels through it. I just evaporates under a vacuum that starts at 17" of mercury and as engine accellerates goes to 22" of merc. To see the details goto my web pages and review the 1983 rampage page. Cost of the evap system is under $15. My ratio of gas to water is 425 to 1. It is 1 gal of gas to 1/3 oz of water drawn in over 1/2 hr traveling at 60 mph. I will be installing a HHO booster soon. But probably as a second system leaving the evap connected and running. I have other ideas that I will be trying and all is reported on my web page.

Hey, I was just thinking this same thing. I've been wanting to add a bubbler for a while and then started thinking, why not hit the whole charge and then I thought, I've got FI and a thottle body, couldn't I swap the throttle body for a old down draft carb and run the carb with water/meth? Carbs are usually brass or more plastic in the newer ones, but water shouldn't corrode it much and meth should prevent that even more.

This seems similar to what flapdoodle was doing with his vacuum draw but I'll be using a whole carb with very tiny jets instead.
