Water/alky Inection Poll!!!

[Slippi84]

Ok guys since I can't really make a poll cause I don't got super secrect level 10000 dsm access just put what your using and which kit you have.

For the guys that weren't in the other thread this is just a poll to see what works better for the water/alky injection

1. Straight Water
2. A home made mix with alky form like home depot
3. SMurf Piss
4.Other

If you guys could put some results even if it's just but dyno that would help the rest of us lookin into water/alky injection out.

wanna hear about this too.

So far, I have been using washer fluid rated to -30. I haven't run any logs on it yet, but the car is faster for sure.

I am going to start using "Heet" (the yellow bottle) because it is nearly straight methanol. You can make more power on methanol vs. water, but water cools better. I will probably run a 50/50 of methanol/distilled H2O.

And I have a DIY setup.

 

[Mike1992]

What consists of your DIY setup and about how much did it cost mr Uncle/Sam

 

[dsm-onster]

I run a distilled water/isopopyl mix becasue it is hard to get a 50/50 washer mix in the summer. and the water in the washerfluid is not didtilled and leads to clogging the nozzle.

Walmart sells quart containers of 70% iso for cheap and most states don't charge a sales tax . They don't need to know what we're using it for do they . 4 quarts = 1 gal. I add one gal of $0.99 distilled water and I've got a consistant, clean mix. With the 70% isopropyl it comes out to about 35% alky and 65% water. This works well witha 100psi pump and a nozzle that flows the same as one of your injectors (450cc, 550cc, 650cc, 710cc, etc.) at 100 psi.

I've run my setup on several different turbo platforms and throughout my testing the water/met mix of washer fluid did no better than my water/iso mix.

EDIT: 21-22 psi w/ small 16g and stock side mount w/ stock fuel system on pump gas at one point. Now i'm running a 60-1. We'll see how far it can go.

I run 100% distilled H2O due to the heat quenching properties (high latent heat of vaporization) and its cleaning properties. Its a homemade system.

 

[Slippi84]

Great info keep it coming fellas but to make this info a little more rellivent if you guys could list what psi you get away with running with your kit and your turbo then it would show how effective water/alky injection really is.

 

[94awdcoupe]

25g
23 psi 93 octane
26 psi with aquamist 100% water or 50/50
33psi alkycontrol.com methanol

 

[1990EclipseGSX]

I run 75/25 Yellow Heet/H20 through a McMaster M10 nozzle. I have a FP3052 and I have run as high as 26psi on 91 with 16 degrees of timing at redline @ 8600 ft elevation. Seemed like I still had some room left to turn up the boost still, also.

Also, I found I had much better results with 50/50 heet/h20 mixtures than with the 50/50 smurf piss. I think the methanol in the Heet is much better than the meth in wiper fluid.

so that would be one slash for methanol. . 4g63-gst, can you describe what you noticed when you switched from water to methanol? did you have to use a much larger injector, if so how much larger? anything you are willing to tell us, i would like to hear.
later

I run straight distilled water in mine. I ran a mix of 50/50 Heet/H20 and couldn't keep the intake temp down where I wanted them so I went back to straight water. With the supra SMIC and the water injection I can keep the intake temps down below 90 degrees with just straight water. This is by far the best mod that I have done to the car yet. I am going to try to run a 30/70 mix Heet/H20 and see what happens.

I am running a Cooling Mist 100psi Kit.

 

[Slippi84]

But it looks like you have a fmic in your picture gallery ChvyKc

I need to take that pic off. If you read the line below it the caption says "Had to get rid of it" I have just been to lazy to take it off. Plus I had a lot of people asking for pics of the FP core mounted on a 1G so it has stayed on there for that as well.

I had that front mount for a little while and decided that it was to big and I really don't like the attention that a big front mount brings. People barely notice the SMIC and they can only tell that I have water injection if I pop the hood so I like this set-up a lot better.

Not a simple subject. In a nutshell you can only inject about 300cc water before drowning the mixture. its only good for a few pounds boost. There is no limit to how much meth can be injected. Obviously the more you inject the better your tuning ability needs to be.

 

[megadeth0]

At one point in time I had this kit installed on my car. I have since redone my entire setup and am still debating on whether or not to install it again.

 

[rowlex]

I'd really like to hear how it works out on the 60-1, as i'm considering alc/water injection running the same turbo. I can squeeze like 20-21psi out of it, with max timing at 10-12 degrees, upto 4 counts knock...

I can run around 500cc. I was able to increase my boost 5psi (from 17 to 22) w/ straight h2o.

 

[Spoolzer]

I just ordered a 100psi kit from coolingmist.com. Does anyone know what size injector this kit comes with and what size is reccomended for a typical dsm setup? Which seems to be 16g, 650cc injectors, fmic 20psi etc. not trying to steal the thread but I think this is a very relivant question

A very GENERAL rule of thumb is to get a nozzle that flows about 80% of one of your injectors. Raise and lower your pump pressure for any dialing in you need to do...

 

[Slippi84]

I thought you were suposed to get it the same size as one of your injectors? Can you adjust the pressure of all pumps or just some company's pumps?

Yea. I've said that before... To rephrase: 80% to 100% of your injector flow seams to be all most have ever needed. Many have reported that only 40% has been enough. This is with pure H2O.

I can adjust my pump psi with my aquastealth kit from BeCooling and every Sureflo pump I've ever bought for a homemade kit. If you can't then you spent alot of money for something inferior . There is no excuse for some of these companies to charge so much. The customer services doesn't merit it. Or either BeCooling has a supernatural business plan and business model!

To adjust my pumps, there is a very small allen screw on top of the pump. Clockwise raises the pressure.

I would like to know which one it is. If it can go with a bigger injection and knock temps down even more then I want to do that.

From my experience 80% or 100% doesn't make that much of a difference with pure H2O. In fact, most I know have found that as low as 40% is all that is needed. I said this amount so that you guys could get plenty of nozzle for your tasks, as nozzles all cost the same price. It's like getting DSMLink, and then getting 650s instead of 1000cc injectors. They can be had at the same price as 650s .

To my knowledge, we all use Shurflo pumps, with the exception of Aquamist. I have pictures of a couple of pumps you could compare yours to, but I believe there would be a vendor issue since they have a brand on them. If you want the pic, just pm me.

As for the adjustment, all Shurflo pumps take a 5/64" allen key on the top. Screwing in increases the pressure, screwing out decreases it. The maximum pressure is dictated by the pressure switch, which is what you are adjusting. You can unscrew the pressure switch (the actual switch, not the allen screw), and you may even see the pressure range of the switch. You can actually set the pressure above whatever the highest number on the switch is, but at some point it will just always be 'on', instead of maintaining a pressure.

By varing the pump pressure, you can as you know vary the injector flow rates. Here is a chart to show you what raising and lowering the pressure will do to the output of a given injector:

You must be logged in to view this image or video.

When adjusting the allen screw, generally speaking (this is not dead on accurate, just what we have found to be common) one full turn changes the set pressure point 20 psi. That is not set in stone, but it is in the ball park. So if you bought a 100 psi pump, unscrewed the allen screw one complete turn, it would now output roughly 80 psi.

Thanks,

Greg

Thank you very much for that clerification . You get points from me.
