May 25, 200619 yr Howdy all, Interested to hear what people have to say about the topic. I am planning to inject via 2 375cc injectors in the inlet tubing (after supercharger). As I am dedicated LPG, I have a redundant fuel tank, lines and pump all in place and waiting for a tankfull of water. Will an electric fuel pump (NA) supply enough pressure to vaporise the water? Thanks Matt

Thanks Matt an FI type pump should do it, a carby pump only supplies about 6psi how are you going to regulate the amount of water going into the inlet?
May 25, 200619 yr My guess is that will be Waaaaaay too much water. I had run Water Injection in place of an air2air intercooler on several 2.2 turbo'ed chryslers. I had installed a kit, that cost about $75 in 1990's $$$'s. It had a pump built into the bottle, and it held 40 oz's of water, or alcohol/water. The nozzle went in after the turbo, and made a HUGE difference. We were routinely taking our boost to 20 Lbs, and showing local Mustangs & Camaro's our Backside! I think you'd be wise to go with a kit, evaluate how it works, and then work on improving certain aspects of the design to fit your needs. Starting out building your own sounds like re-inventing the wheel. Best of luck! Fat Tony - http://www.smashbandits.com
May 25, 200619 yr No experience here, just an opinion. I think you'll find you flow way too much water with those injectors. I would start small and work my way up.
May 25, 200619 yr The finer the mist the better. Injectors of that size won't mist fine enough.Goto a hardware store and ask them for a misting nozle for plants.They put out a nice mist perfect for water injection!
May 26, 200619 yr those injectors will likely be too much. On a gas engine, a common number is 10-15% of the fuel being injected. It's a good idea to mix in a little MMO so the fuel pump and injectors don't rust up solid
