Water Injection?

[94fbody]

Guys&Gals, what is the real truth's, lies about water injection in a vehicle, mainly does it work? What are the Real benefits, is it worth it, what's the deal somebody? There are a lot of mixed claims out there, a company called AquaTune seems to have a fairly sound product when you read the product details, but perhaps someone who has actually tried it for themselves can detail more.

Check this out, good info [img]smile.gif[/img] I don't have it, but plan on it.

I had good experience with it years ago on my T-bird with a carburated high compression V8. This had a 429 CI engine with 11.0:1 compression and a fairly mild cam. The factory recommended fuel was 100 octane leaded premium (equivalent to 95 pump octane the way gas is labeled now).

This car really needed high octane gas to run well. When leaded premium was no longer available I installed a Spearco water injection system that basically put a water nozzle above the primary barrels of the carburator. The system had an adjustable vacuum switch that turned on the water that was pumped from a tank to spray into the carburator. It only operated at low vacuum conditions. Normally I had to fill the water tank (about a gallon) once every gas tank fill up (about 20 gallons).

It worked really well to reduce pinging and knocking from low octane fuel. I was able to keep the 100 octane spark curve with the 92 octane gas that was all that was available.

I ran this car over 100,000 miles with this system installed and the only problem I had was the water injection nozzle clogging up when I used tap water. Distilled water didn't clog but I didn't feel like spending money on it at the time.

I don't have any idea what is now available. I don't see how it would be much of a help on our cars, unless they were supercharged or turboed.

Would water injection make large timing advances possible? If so, would the water just cancel out the effects, or could it possibly make the vehicle more fuel efficient (with the timing advances)?

Thanks for the info. I really apreciate it.
