Water injection

[dodger]

I plan on using this this year on my car,and just wanted to know if any one else is runing one and how they like it.
Iam just going to buy a kit on e-bay that way i have all the parts that are tested.

I use the snow performance kit, on the Daytona. So far I like very well. I bought mine on ebay from Matt Snow. Service was great,staight forward easy installation. I use just a single stage, set to come on at 13# of boost, injecting "winter" washer fluid about six inches in front of throttle body. Have run 23# of boost on 93 pump gas and stock intercooler.

I'm planning on running alky in my TII GLHT this summer. I'm going to be using Aquamist nozzles and a universal pump. My friend has a very similar setup to mine on his Syclone and was running 28psi on pump gas with zero knock.

Mine's going to be a 2 stage setup. However, there will be more parts needed to do it this way. I'm going to need:

2-adjustable hobb switches(pressure switches)
2-grainger valves
pump
nozzles
GM boost solenoid
tank
and some hose.

Here's my plan.

Plumb in the 2 grainger valves on the 2 outputs of the GM boost solenoid. Run one hobb switch off of manifold pressure at 10-psi to activate the alky pump. The W/G will be running through one of the graingers(the low boost one) which will be set to about 12psi or so. Once I hit 10psi, the first hobb switch will activate the alky pump and pressurize the system. The second hobb switch will be in the alky system, so when the alky system is pressurized, then this second hobb switch will activate the GM boost solenoid and switch the solenoid to the other grainger(higher boost), which will switch the car into high boost all by itself. Does that make sense?

Basically, with this setup, I run low boost until the alky is pressurized and spraying. Once it is spraying, then the car will switch into high boost safly now that I know my alky is already there.

There is a much easier(and much more common) way of doing this also. You'd adjust the W/G to run say 20 psi all the time. Then you could run the alky pump off just a regular hobb switch(just one) at say 10psi and that'll turn the system on and you're off and runnin. However, if the alky tank is empty or the pump fails, you're in big boost with no alky.......KABOOM. The way mine is setup, you won't get high boost until you know the alky is flowin.

I'll be injecting that "Heat" stuff you put in your gas tank in the winter(comes in a yellow bottle). It's a mix of alky and methonal. My friend tried all kinda of fluids in his truck, straight tap(regular) water, distilled water, washer fluid(water/alky), isopropal, and the "heat". The heat workes the best by far. Water is OK, because it cools. Alky is better because it cools and adds octane at the same time. And if you don't get perfect atomization, the alky(heat) just burns, unlike water.

Whos the maker of heat?

Iam cosidering one of those kits,glad it working like they say.
Thanks for info

THIS is a pretty good kit. For the money it is a fairly complex (as in design, not installation) system.

[dodger]

For $360 thats way too much,nice kit ya,but $360 is close to robbery.

[macncheese]

sy2206, that sounds like an absolutely fantastic idea. and i thought my three stage boost controller was sharp!!! i'd really like to see how that turns out. keep us posted!

I did alot of digging on this topic before deciding on the alkycontrol.com progressive kit.

For lots of good info on this topic, go to turbobuicks.com. Their alky forum is the best place for this type of info Ive found.

I've been running a home made alky/water injection for over a year. The only concern I have is the location of the spraying.

On my setup, the spray was before the throttle body. I think there is a drawback to this. I believe that the air coming in to our engines must first bend around the intake elbow. Then it has to drop down (more in the 1 piece) into each cylinder. Since the air is lighter than the liquids we inject, much of the spray ends up plastered on the elbow wall because of centrifugal(or is this centripital?) force. I also believe that much of it overshoots cylinder #4 so #4 runs hotter. This is not and issue with the regular fuel injectors because they each spray right into it's own tube and also right at the head.

I just blew a head gasket because of detonation on #4. I'm rebuilding the setup with alky/water injection again, but this time I'm going to try to spray right down into each cylinders tube.

This is theory, I don't have facts to prove it other than a blown gasket and head.

The other minor issue with spraying before the throttle body is that when I get off the throttle fast, the spray in the tube gets sucked backwards into the blow off valve and I can smell lots of alcohol. I don't think alcohol spray in the engine compartment is a good idea. I currrently trigger the spray based on manifold boost pressure, but I'm considering switching over to using the throttle position (maybe along with boost pressure) since I think it will turn the spray off sooner. For those running water only, this may not be an issue.

I welcome any comments or feedback

I think alot of this has to do with how finely the alky gets atomized. If the mist is fine enough, the air should more or less be saturated with alky much like normal air would be with higher humidity levels. If this is achieved, you wont have to worry about alky falling out any more than youd have to worry about the moisture in the intake air falling out.

i ran the spearco kit on my corolla and ran staright alcahol .....my egts dropped dramatically (my corolla was bossted and used the alcy as the only fuel inrichment )
it added a solid 50 hp on the dyno , due to the fact i could add more boost . best 390 bucks cdn i could have spent . the best part of the spearco is the pump is cheap . they use a presurised resivior and a plain washer pump . that way the pump only has to over come a small amount of boost as opposed to the kits that use the pump to make like 25 psi or more .

That's a good point. However I don't know if any alcohol manufacturers specify how much atomization each of their systems boast.

Actually, I was amazed at how little atomization occurs with our regular gasoline injectors. My + 40s seem to shoot a stream rather than a mist. I used cold start injectors for the alcohol and they put out a cone of spray. Although the alcohol cone was better than the gasoline stream, I still don't think that it all that perfectly well atomized. I spray the alcohol at 55psi over boost.

I think it depends on the system as to what type of atomization is achieved. The alkycontrol.com system I use uses 150+ psi pressure and nozzles designed to atomize. Ive checked the output and its very very fine. I could see how hot dry air could easily "absorb" this mist espcially when combined with alcohols tendency to easily evaporate.

I too have noticed how "regular" injecors spray.....it is more or less a stream compared to how the alky nozzles spray. But, that seems to work too
