What's this? Edelbrock Vapormaster?

Good, bad, ugly? What's it REALLY do? Anyone ever used one of these? How's it behave with this added onto it? Any real advantage or disadvantage?

This looks familiar snake... Popular Mecahnics has something a friend told me about which injects water but basically the same concept. Cooler engine,cleaner burn, leaner burn,keeps combustion chamber clean,better fuel economy, yada yada yada... not sure if it works. I would imagine if it did they would be still making them.

I have a friend who owns a local repair shop. He is selling a similar but brand new version of this thing. He swears by it! He claims that the ooriginal inventer of this thing lives here locally and way back when he invented it the big oil and parts manufactures shut him down because of how revolutionary it was. I have no idea if its for real or not but I am passing what I know. He says that he has used this on several of his vehicles and it has improved everything! He has even done before/after tests with pulling the intake manifolds off and claims they are cleaner after using this product. Anyway, For what it was worth.

My cousin made one of these for his 65 Pontiac many years ago from a windshield washer bottle. Said it helped keep the internals clean and helped with a little more umph :D He had the car until about 72-73 and got rid of it, but never knew him to have to much trouble with it.

I had a friend that traveled alot in south america and spent a lot of time driving in high altitude areas (8000-11000ft). He said the water injector made a huge differance on his chevy van. At sea leval and the humidity you have in houston you don't need it.

I believe some versions of the Daimler Benz engine that powered the Messerschmitt 109 had water injection, for extra HP. How it works, I have no clue, but I would guess that vaporizing water into the air/fuel mixture will soak heat, increasing the density of the charge, like an intercooler?

My sisters father in law also had a similar device on the market and his used a venturi anode just like a carb that actually went over the carb venturi. The fluid was windshield washer fluid (methonal and water mix. He found that if you got the fluid in bottels marked ACCUPAK on the bottom it did not have a detergent in it and worked better. I had one of these set up on a Vega and could tell when the bottle ran out of fluid so I would guess it was good for about 5 hp. The Vega motor went 180,000 miles before it took the gouge out of #3 cylinder which was about the norm for that motor as long as you did not get them hot and kept oil in them (that was the hard part).
