Installing an Aqua-tune today...
 

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 :p

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

BAHAHHAHAHA! :D You could prolly say you had the cleanest engine in town! :D 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?

unstable bob -

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.

BTW, nice Bel-Air. Def a cool, classic ride!

D0 TELL! DO TELL! :)

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?

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.
