Water Injection ?s

Or better yet stack under the injectors like the newer (NOS, Nitrous Express, etc) systems? If you use one tap in the intercooler pluming, wouldn't you lose a lot of efficiency as the single tap wet nitrous systems do? Basically the issue is that those systems have to take into account the "wetting" of the intake manifold walls in their "wet" fuel delivery... and the possibility of unequal distribution. Now before I get too slammed by our resident forum "gurus", my knowledge is limited with the air to water ratio run in these types of systems. Therefore this is an inquiry vs. a rant as I'm new to such systems...

Which WWF manufacturer did you speak with? I want to be sure to never use his product in the future. The folks I talked with around here that have used WI in the past said it wouldn’t be a problem.
MP5, thanks for the good give and take with David on this subject, it really helps, much appreciated.

The product we use is 100% biodegradable and contains no solvents or any form of methanol. The product leaves absolutely no staining in the reservoir, nor any part of the washer system. The product is not only 100% harmless to the environment but also 100% harmless to the components of our vehicles. Only drawback, you can’t use it in areas where the temp is below 32 F on a regular basis.
I live in an area of California that is totally dependent on ground water so we know about these things.
Unless it’s a biodegradable product the waste must be taken to a disposal center or site designed to handle automotive fluids. Its not even fatal if swallowed! Oh, it is blue, but that’s where the similarity ends.

Keep in mind, we are not offering the WORKS Water Injection as a horsepower mod, but rather, as a safety envelope modification that allows the end-user to run his/her car under extreme conditions without the usual pitfalls associated with intercooler heatsoak.
Perhaps we will do a few runs -- with and without the fans aimed at the intercooler -- to show how water injection is able to stabilize intake temps., but the truly significant numbers to look for with water injection are the ones that one might see logging data on a hot day running multiple laps at the track, or with a temperature probe showing intake charge temperatures after crawling through heavy traffic on a hot day.

Interesting, so do you now have plans to offer a front mount intercooler? I mean since FMICs now have a proven record of adding power on the Evo that the WI seems to not (being a "safety mod")...
The FMIC's and the WI both do the same thing. The disadvantage of a big FMIC is the pressure drop. The WI also provides the user the ability to tune the car a little closer to optimal performance in all conditions.
Since I am an engineer, I have to give big thanks to WORKS for taking a big risk in developing such a system for the EVO owner. It won't be long before the other tuners will want to buy or make there own.

Yes and no. I was pointing out that some of the bolt on FMICs are putting down as much as 20-25whp on the dyno without tuning... Does the WI do this? Of course it could... but that's not what David is saying. He makes it sound as if it does not produce much power on the surface.

There are many ways to fudge a FMIC effectiveness on a dyno it rarely has to do with the ability to get rid of intake charge heat but the newer better FMIC getting an extra turn on the boost knob or a degree of timing to take advantage of the "theoretical" capacity of the bigger core or to "level "the boost pressure drop of the bigger core to take the measurements at the same psi (usually the WG is already shut so fuel and or timing need to be adjusted). The only way to truly test the effectiveness of a FMIC is flowbench it and match it to the TC. All else is just feel good fufu stuff

Ok, bad example without a little more info… Do you agree that the OE base map tends to pull timing under certain circumstances (vague for a reason)? It seems many have datalogged the event. Would it not stand to reason that the intake charge having a significantly lower temperature would produce more power by allowing the ECU to run more advance? (Similar but different arguments for the upgraded pump keeping the knock count down) The WI should produce the same effect as a FMIC, or better, depending on how much the H2O slows the combustion event. My whole point (a fishing expedition for David) was that he (David) said that the WI wasn't so much a power adder as a safety net. My argument was that acting in a similar fashion, a FMIC "adds" power so why does WI not... get my round about drift?

) The LAST thing works wants is a leaner charge from a big IC as the route they seem to be going is taxing on the fuel system without WI. See Kinda what Im getting at? If not pm me
I think we are talking about the same side of similar coins...
My main point was I was trying to illicit a response... David has a history of answering questions as a part of others if you know what I mean

Zeus Even Aqumist states that WI does not make power it allows power to be made in certain apps. Otherwise as you point out, it serves mainly as an anti-detonation safety measure and a way to ease the load on the injectors and fuel pump. As you know, water quenches fire by cooling (slightly by evaporation and largely by converting water vapor to steam) and smothers it as a vapor or gas (steam). The pressue resluting from the steam production partially offsets the energy absorbed by the endothermic process. The net effect in the combustion chamber is lower pressure and therefore lower torque production. The key benefits derive from using the minimum amount of water necessary to prevent knocking. The questions to Works are how well can their system regulate the a/f/w ratios and is there a drop off in power with the Wi with the p2 and wi reflashes compared to the p2 alone. Vishnu had poor results when using WI with the WRX. Looking at what they did it seems the system from aquamist may have over damped combustion.
