I've liked water injection since I saw it mentioned on a NOVA show about Hydrogen powered cars, back when I was a kid. I think it's main use to date has been to cool the boost produced by turbochargers. It doesn't seem to be widely used. Still, I think it is one of those things with undeveloped potential. | ||

I've used it on several cars. I ran a 50%water/50% isopropol alcohol. It would allow you to run more timing and or boost but i'am not sure were you would put all the stuff to run it on a M/C. | ||

We played around with some very crude water injection systems back when gas went over 1.00 a gallon the first time(yes, I am that old) Our systems while lacking in electronics,meters or other gizmos did actually add a couple miles per gallon, or at least we talked ourselves into thinking so? I don't even remember how we rigged them up( yes, I am that old too) but it had to do with vacuum,a gallon milk jug and a small valve. | ||

I love these old geniuses. Here's your water injection. http://www.autoweek.com/apps/pbcs.dll/article?AID=/20060224/FREE/60222004/1024 | ||

We have used water/alcohol injection for years on our 1987 Grand National. Systems arms at 10 PSI boost and starts flowing (using a nitrous jet) at 15 PSI. The mixture is injected directly into the throttle body. We use a walbro fuel pump, and mix a couple of teaspoons of caster oil to prevent corrosion. This allows us to run high boost on 91 pump gas. With no ping. However if the injection stops for any reason you get to replace the head gaskets, and they are o-ringed. John | ||

i run an aux illiary methanol/water injection system on the race car. very crude/ simple, swithces on at 90% throttle, sprays 4 gallons per hour through a pair of home made .016 jets. pump is a 12 volt windshield washer pump, bypass through a t fitting to reduce pressure. | ||

Fullpower - Did it help your performance? | ||

Unless you have problems with knock or advanced timing I would not see the need. Unless you plan to turbo or drag in hot weather. | ||

I talked with a guy once who built some sort of 4wd drag racing vehicles. They ran nitrous. Since the nitrous serves as an oxidizer, I asked him why they just didn't inject oxygen. He said the engines would melt if you tried. I've wondered since then if it would be possible to use water injection to make oxygen injection work. If you could pull it off, it seems like you would be able to get an incredable amount of power. |
