OK so i have a 74 Satellite Sebring Sundance with a 77 440. The engine has flat-top Pistons with 9.5-10:1 Compression, a comp cam with .480 Lift and thats about it. I have heard from some of my dad's friends that water injection is a good way to make some horsepower, but i haven't heard much about it in naturally aspirated piston engines. Only Turbo-supercharged engines and turbines. How much power would it free up in my 440, and is it a reasonable thing to do? And if so, should I buy a kit, or simply make one?

interesting theres no replies to this question, i hope you are talking about hydrogen derived by water being broken down, cuz i dont see any advantage in pure water injection. the world should run on hydrogen already in my opinion. not petroleum. its relitively easy to break water down into hydrogen, which itself is extremely explosive and hot burning. but its close to gasoline in a four stroke from my understanding. ive seen videos of sludge and buildup being broken down and cleaned of engine components after running hydrogen. research it. be sure to put stan myers in youtube

I don't know how true it is, but I had heard at one time of guys using a water "drip" into the carb. I guess the idea was that water does not compress, thus it would add to the compression in the cylinders.

Do I think it sounds like a good idea? No, just something I heard one time.

This so called hydrogen or hho injection is a scam. It takes MORE POWER to break down water into H2 and O that you get back out of it.


Water injection CAN help. It's primary function --dating back to WWII and before -- was to prevent preigniton and detonation at high altitude in super/ turbo charged engines. It slows the combustion process, effectively acting like "a little more" octane, and helps save the engine.

I have no idea of it's real world benefits on a med. compression street engine which PROBABLY ALREADY RUNS some alky in the fuel. Very few states, if any run straight gasoline anymore. In many places the law favors the meth farmers, and they DON'T EVEN HAVE TO TELL YOU that there is alky in the gasoline.

my father claims it does help, how much i was told varies from engine to engine. no more than 40hp i was told. the mix is just a jug of windshield washer fluid.

He is taking about a system like the one in the link. It uses windshield washer fluid wich contains methanol,works great for boosted cars or radicaly built motors but the gains on a stock to mild built engine would hardly if at all be noticed.

Just my opinion, Bob

Ya Maddawg and i have already discussed it. And the advantage of it is that it cools the charge and makes combustion slower and smoother, allowing you to advance the timing more. It is mostly used in jet engines but people run it on supercharged engines alot for cooling and a little extra "octane" boost. I had just heard its useful on free breathers too so i figured id ask some more experienced people.

he said they made their own systems., but his glory days were the 60's

weren't some cars made for water injection in the 70's?

im trying to scam you buddy. i scam people all the time. You wanna buy some hydrogen making stuff off me. lolol. seriously though, MY OPINION STANDS THAT ITS THE FUEL OF THE FUTURE, facts aside cause nobody cares about it here anyway. plus typing really can only get you so far.

The only uses of water injection i have seen were aftermarket systems intalled on motor homes. I believe its claimed benifit was to help with preignition.
