Water injection..experiences and opinions please

Featured Replies

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

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?

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!

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.

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!

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
