Installing an Aqua-tune today...

[unstable bob]

I've had an Aqua-tune H20 injection set up sitting around from a Caddy I used to have, so I decided to install it on my Cavalier today. It didn't seem to work wonders on my Caddy, but that POS fought every mod I tried to make to it. I'm hoping for better luck on the Cavvy. I'm at about a quarter tank of fuel now, so by Sunday I should need a fill up and will start monitering things.

Cool Years ago I did some experimentation with water injection... And discovered just how much water you can put in a engine without hydro locking

My exhaust was shooting out liquid water, there was a puddle behind my car

BAHAHHAHAHA! You could prolly say you had the cleanest engine in town! Hopefully the Aqua-tune will not be dumping that much water into my engine. Although when it was on my Caddy it did seem to like the stuff enough to suck up a few bottles in record time. Dayum wateraholic!

I have been researching water injecting for a bit, what does your system use? I have seen using the vacuum to pull in the water. Does yours have a pump or rely on the manifold pressure?

I *think* my co-worker friend used a system like this in his (carborated?) truck in the 1980's. Along with great MPG, the smog tester dude said it was the cleanest emissions test he ever saw. I need to interview him for all the gory details, so I can post it as a case study.

Mr Bean,
The Aqua-tune uses vacuum to pull in the water. It is a pretty simple system, with an easy installation process. The hardest thing I had to do was find room for the water reservoir. I've heard pros and cons about the set up, and it is pretty expensive. But since I had it sitting around I figured I might as well give it a shot in the new car. And if it doesn't cut the mustard as an H20 injection set up I figure I can always use it to inject other chemical concoctions to try and help with mileage. I'm looking to buy some software to allow me to reprogram my ECM with a lap top, so I'm hoping the H20 injection will allow me to run more timing and such as well.
The website for Aquatune is www.aquatune.com
BTW, nice Bel-Air. Def a cool, classic ride!

Oh, that's not just water injection. They are splitting it and putting the hydrogen into the engine. Is yours that way or is yours an older model that is just water?

[Fourthbean]

I was considering putting THIS together to see if it has any affect on my car. The only problem I see is that I run my engine at a vacuum of about 5 and then glide with the engine off. So there would be much more water coming in at idle (18 vacuum) than when I actually needed it.

I may try putting it in and trying it with a different driving style and see what happens.

I had one of the older models on my Caddy, but sent it back for one of the "modern" design ones for my Cavalier.
