Dave is that an aquamist 1s mounted on an Al plate???

 

Ok specific question on how this works?
Let me know if I am right,

The water is injected into the fuel to reduce the amt of volitility in the combustion chamber?

This allows more boost and lower temperatures?

Is there a horse power gain to this set up, (seems like it offsets it's self, lower combustion power because of the water, but more air raising the combustive property of the fuel that is there)

If this is true, the achieve the same power, there is more boost lag because you need to reach a higher boost presure?

If I am totaly wrong, please let me know what the deal is with this set up.

 

On the right track. Works must do one of two things to make this effective. 1) lean out the fuel compensating with the WI to cool the charge as well as raise the effective octane level to prevent knock.
2) Raise the boost to essentially do the same thing (lean the mix) and using the WI to do the same as above.
I have seen many a WI system actually loose power and go rich cause its not being used properly. I see no need for a serious (and 1K is serious) on the stocker as there is enough fuel there, but they could run low IDCs lean it and use the WI or they could be thinking the WI could be used in place of a bigger pump and injectors on their upcoming Big turbo setup.

Other than that they will only be squirting a tiny amount of water- we will see

 

Nope. 1S is controlled by a simple pressure switch. The WORKS system is closer to the 2D since it is mapped off of the fuel injectors.

Good anaylsis. You are more or less on target with where we are going with the WI.

In essence, we can get away with running a more appropriate (leaner) AFR than would otherwise be possible, raise the effective octane of pump gas, and potentially obviate the need for fuel system upgrades for an upcoming WORKS turbo offering.

Thanks for the clarification. What benifit will this have for the p1/p2 customers and is the fuel going to be pulled from the mape to accomadate the WI? to what extent?

 

IC this will then negate the extra cost of injectors and pump. If the washer bottle is going to be the tank then in the event of a run out of water how will the WI system pull boost? Are the secondary maps going to be deployed? Are they going to be much more conservative than the factory or are you going a secondary solenoid route?

 

Side note: something that's bothering me after the comments about the "washer/IC spray bottle" and what your supposed to put in it... There is no single such thing on the Evo. The washer "bottle" for the front and rear washer, is in the trunk of the car. The intercooler "bottle" is stand alone, and behind the driver headlight. They have nothing to do with each other. So you would continue to put washer fluid in the washer, and whatever Works recommends for the intercooler/WI spray. I do find the question of windshield fluid interesting, as what are you to put in it when faced with freezing weather?

 

Thanks for clarifying. The reservoir feeding the WORKS Water Injection is the intercooler spray bottle mounted adjacent to the factory airbox. This can be filled with washer fluid to prevent it from freezing in the winter. The dye and alcohol contained in windshield washer fluid will do no harm to the WORKS water injection pump, injector nozzle, or other hardware.

Yes I wasnt clear which bottle theyd use so I morphed them

 

more interesting still... I'd think the alcohol would change the air fuel curve significantly...

More side bar: David, when will we see numbers posted on the cams? Are we going to be wiating as we did with the P1?

 

We provide alcohol mixing guidelines for the kit. As far a the dyno graphs go for the cams and such, these were actually ready some time ago but I have been having difficulty capturing images from the dyno viewer software to post on the website. I'm hoping to have that resolved shortly.

Nice, I'm sure we all are looking forward to seeing the entire hp and torque curves.

 

If you continus to use the Blue Windshield Washer Fluid (WWF) in your WI system, you'll regret it. I recently contacted a WWF manufacture and told him how we use his product and explained some of the problems in doing so. He replied saying that he thought we were dumb for squirting WWF in our engines and said the EPA would have a fit if they knew we burning such low grade alcohol and our engines were spewing out its byproducts into the atmosphere. I think he misunderstood how much WWF I was talking about, but he did say tha the WWF contained: Surfactants (a wetting agent and emulisfier) some alcohol (amount depends on how cold it gets in your area) and a few drops of blue dye and of course water. The Surfactants help your windshield wipers remove the grease and bug guts from you windshield, Surfactants also keep all the solids (minerals & junk) in suspension until they reach an obstruction (like a nozzle) or if you are smart a filter, where it collects and clogs everything. He didn't say what find of alcohol was used, just that it was about the cheapest kind available. This makes since you can buy a gal of WWF for about a $1.00 and a gal of generic drinking water costs more. I've switched to distilled water and enough methanol to prevent freezing (which is rare) Jack

 

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.
