Any results from Aquatune dynos?

[Magnus]

Some things to think about...

Isn't this system driven off of vacuum. I thought it was designed to be a fuel economic system that shuts off at WOT... hmmmmmm....

The thought of injecting water into my engine makes me cringe. *shivers*

This water does not take up space? Because if it does obey the laws of physics and all, thats less room in the cylinder for things like AIR and FUEL.

And.. if the "theory" is that it evaporates in the cylinder.. this comes to mind...

Where will it be injected? If it is before the MAF, how many replacement MAF sensors will you go through. How will water getting on the MAF sensor affect its readings.

What a waste of combustion space. *sad sigh* :(

the whole water thing in the engine is what bothers me too. water no likey to compress.

The water being injected should take up more room in the cylinder, leaving less for fuel and air, but the hydrogen that is supposedly produced from this water injection is far more combustable than 87 octane gas and also the left over O2 being brought in thru the water injection will replace the air that must be taken out to clear room for the water injection. This air would be even better in my opinion, because all of the O2 coming from the water injection is in fact pure O2, nothing else which should allow for better combustion per liter of air. This as opposed to the air that is being brought in from outside the car, which is mostly nitrogen gas.

This is just some of the stuff that I thought i remembered from high school and college physics and stuff, but I could be way wrong, sounds right to me though.

Also, would you be able to cool this water somehow maybe in the bottle. That way all the O2 goin into the engine would be cold, which is what we try to get anyway. Just a thought.

you can tell me all the chemistry you want, it still isnt going to make more power, dont they use water to put out fires??? thats all its doing! putting out the fire in the combustion chamber, that little aquatune deal isnt going to perform fission right under the hood on the water molecules,

Yikes, lots of bad chemistry here...

You are getting steam or water mist injected into the engine -- not hydrogen. Aquatune are a bunch of lying sob's (look at the dyno results on the 97 grand prix, the after, look at max power, see how it is read from the torque scale?). That car gained around 2 hp.

The only reason you inject water into the engine is to cool the incoming air to keep away detonation. If you are not running a high boost application, don't waste your time.

However, water injection will not harm your engine unless if you manage to bog the engine with water. Water is a by product of the internal combustion engine, why else do you see water coming out of your tailpipe every so often?

Again, this is nothing new! Spearco has almost a similar system to this. But nevertheless this debate has gone on for to long. I've been looking for an intercooler and Spearco sells an expensive one. I'm leaning towards this and who know in the middle of this year it might be in my car. I'll definately let you guys know how it is.

[ChrisV6]

http://www.aquamist.co.uk/ produces something like this, too. For me it makes also only sense on boosted engines (&gt;9psi) to cool down the incoming air and prevent detonation.
Cold air and fuel is the best mixture,
but why should I try to cool down incoming air that isn´t heated up?! It would be as senseless as installing an intercooler on a non-supercharged engine...

Yes, they used such a system in WWII on planes, for example on the Messerschmidt 109, but this plane had a huge supercharged 12cylinder engine and they injected water and alcohol! (output 1450hp + 400hp, but only for 4 minutes)

This is the system i had. :(

chrisv6 you say cold air and fuel is the best mixture. I would agree with you if air was pure oxygen. In fact the majority of air is nitrogen. Hydrogen burns longer than nitrogen so guess what cold air and fuel isn't the best mixture. Not trying to down ya but just proving a point.

[Deuce Bigs]

air is free. since it seems you want to argue just to argue sure you could prove us all wrong and build a pure oxygen/fuel engine and run it, prolly have to be made out of unobtanium to take the power, and i don't wanna be around in case the oxygen tank blows.

you need the nitrogen so pretty much everything doesn't burn up. oxygen is extremely flammable by itself(when it has a fuel source). why do you think nitrous is two parts nitrogen?

The ideal motor would have to have perfect combustion. Perfect combustion is 2 parts hydrogen and one part oxygen hence

H20 -&gt; 2H+ + O-

Hydrogen will not burn without the presence of oxygen not nitrogen. I was wondering why you say nitrogen must be present so that everything doesn't burn up. [img]graemlins/bs.gif[/img] Im not trying to piss everyone off but instead im just waiting for dyno results from viper98885

[2WISH4]

Soooooooo... if they're saying to pay a bunch of money to spray WATER into my engine will make power then how much extra horsepower will I get if I just pee in my gas tank? :eek: [img]graemlins/dunce.gif[/img] :D

@Chuck:
I´m a bit confused.
Yes, hydrogen burns better/longer then nitrogen, right. But why are talking all the time about hydrogen? Dou you think the injected water will splitt up in oxygen/hydrogen?
Or did I misunterstand you?

[Dominic]

If it trully worked, and conserved fuel, the EPA would have it on all of our cars already!

[Deuce Bigs]

water is the perfect combustible? cause that's what h20 is. have you tried to light water lately?
my point is it's the oxygen doing all the work. oxygen (with very little to interact with)is extremely flammable. ask your chemistry teacher. oxygen is what keeps a flame burning. when a flame runs out of oxygen it goes out. these are basics you have to understand. go stand in a room of mostly oxygen. besides getting high from it light a match. you'll be dead really quick. the room will turn into a huge fireball. go watch backdraft. the reason the fire comes shooting out is the introduction of oxygen. nitrogen is one of reasons when the first caveman made fire all the oxygen in the world didn't ignite. if you're talking about hydrogen/oxygen being the perfect combustible i'm guessing you're trying to talk about cold fusion in which case a conventional four-stroke engine model does not work. it's a completely different idea.

go read some chemistry books about nitrogen, oxygen, hydrogen, cold fusion, and such and we can talk more. no offense but you have some basics to learn first. those systems can be used in our cars. prolly won't hurt much, but it also won't help much. unless you wanna talk abou thte weight factor but in that case the weight of the system will be more than the weight you dropped in your wallet so again that's a moot point.
