Water/ Alchahol injection for boosted engine? idea, I think

[Matt167]

what will I need for water/ Alchahol Injection for a engine running 10 PSI boost, I'v been told the washer pump won't work because it can't overcome the preassure, so what kind of 12v automotive pump will work?


I also got this ingenius Idea, that if it would work, would not need a pump. If I took a stainless steel coolant recovery tank ( I'd get a big 1, not the 23 OZ like I'v got for the coolant ) with the 2 hose fittings, the 1 that's a vent line that runs to the top, and the other, that starts at the bottom. If I hooked a preassure line ( from turbo outlet ) to the vent line, and then ran a line from the bottom of the tank, to a cut off solonoid, that opened with power, and run that to a preassure switch, set to a low PSI, and then switched that on/off with a toggle switch. so when alchahol injection was not needed, the solonoid would not activate, the recovery tank would just have a little preassure put in it, but should be able to handle 10 PSI. The preassure coming out of the turbo is always 2-3 PSI more than what's at the intake, because of preassure drop thru the pipes, so if the gate was set for 10 psi, and I refrenced the alchahol system to Turbo preassure, it would be 10 psi, turbo at the intake would be 7 or 8 psi, so it would have 2-3 psi to make atomization, thru the nozzle in the intake ( actully pipe, just b4 carb ). would this work?

Snow Performance has a great line of water/alcohol injection systems. Put one on a guys 4.6 Mustang Supercharged last summer, he sez it works great. Got that one from Sumitt....

It's great until you run out of water/alcohol at full boost.

what if you just run e85

[Matt167]

only 2 gas stations I know of that sell E85 anywhere near me, are still an hour away, I'm still setting the engine up for E85 ( correct rubber parts for the alchahol ) because 102 octane.

I just want the water/ alchahol injection system, so I can run a little more timing at the drag strip/ when I need it. I got the MSD 6 BTM, so I will have the boost timing adjustment right there asessable from the drivers seat.

go with the stage two water injection from snow performance (at least i think its them, the only one they sell on summit)

I want one for my wifes volvo and haven given some serious thought to how to tell when the tank is running low. She's not dumb but being a girl she has a tendency to not pay attention to gauges when she drives. I think the best thing would be to replace the water tank the kit comes with, with a 3 gallon fuel cell. You could easily mount the cell in the trunk without losing too much space, plenty of capacity, and you could use a standard gm fuel level sensor hooked up to a fuel gauge of some sort. You'll always know how much you have so you don't accidently kill your engine. (biggest downfall is the added weight of 3 gallons of water, so you have to remove something else non-essential, like the brake master cylinder or something. )

why dont you hook it up so when the tank gets low theres a constant loud buzzer..... she'll think its about to blow up and call you for help everytime

If she's like my wife... that won't work either... She drove her van for a week with the oil light on and dinging noises before remembering to mention it to me. BTW... that one was SHOT...

The motor ... was shot... not the wife... although at the time... I was angry enough to. I was working double shift for a month and a half... would call her to remind her to check the oil cuz it burned a little... after that... she had to stop to fill the oil and check the fuel in her newly converted fog machine.
