Water/ Alchahol injection for boosted engine? idea, I think
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?You don't know what you've got til it's gone
