More Zuk Power, maybe ...............

Anyone ever mess around with "water injection" for your engine? It can actually increase power, reduce knock, and provide a much cleaner combustion chamber. During WWII the P-51 Mustang and the P-47 Thunderbolt used a similar setup. There are products on the market, but they cost an arm and a leg. I was hoping someone had messed around with this and could offer some info.

Re: More Zuk Power, maybe ...............

With as fragile as the components are internally on a Suzuki engine, I don't know if the design is up to the lean charge induced by a water injection system. Maybe?

It would be wonderful if a way could be designed to utilize a good water system without causing any problems. I am sure there is someone on this board that has the knowledge or experience to make it work.

Re: More Zuk Power, maybe ...............

2 ways to water inject. Forcibly, or by vacuum. Forced H2O injection is best as you get the benefit even under load.

Vacuum is fair. I have done several using a bleed into a carb base vac line and a small reservoir using a 50-50 H2O and methanol mix. Works pretty well and doesn't lean it too much, but watch it. Factory ECU controlled carb/FI setups will tend to correct for it. Webers will not.

It works by the vac line going to the top of the reservoir and a bleeder valve feeding air to a hose at the bottom of the reservoir. Bubbles the mix, and you can adjust how much it bubbles. What it does to the mix is 2 fold. Cools the charge (except at WOT) , and helps clean the carbon out of the combustion chamber, and keep it clean. In very High compression engines we used it in it allowed us to burn premium without pinging. (I SAID they were high compression!)

We also played with some fuel additives in the injection tank with some interesting results.

Watch your plugs and water temps and have fun.

There is a company in Australia that makes a water injection for EFI systems. The instructions are available online, but they do look promising.

Jim, do you have a link for it?

Somewhere I do. I have so much darn junk though, it may take some time to find, but when I do, I will send it to you.

That was easier than I thought.
