I'm bored, and awake at 4:30 AM, to here is some basic information for those just learning about alchy systems...
Components:
Tank: could be the overflow tank, of windshield tank. Anything that will safely hold an alcohol mixture will do.
Pump: Shurflo, or Flojet. Both handle denatured alchy.
Hobbs Switch: Any pressure activated switch. This is mounted on the up-pipe (for instance) and has 2 ground wires running to it. It is adjustable, and closes the circuit at a pressure point you select.
Solenoid: used in a 2 stage system to activate the second stage. Activated by a second hobbs switch.
Hoses: Anything that will safely carry the alchy from the pump, or solenoid, to the nozzles.
Nozzles: last stop for the alchy, before entering the up-pipe. As the pressurized alchy passes through this, it is forced trhough a small oriface creating the desired spray pattern or fine mist that enters the intake, and is digested by the engine.
Here is what happens when you go wide open throttle:
Boost rises to, say, 12 psi, on it's way to 22 psi. As 10 psi level is reached, the hobbs switch (located in the up-pipe) sees the 10 psi level you have set it to sense, and closes its internal contacts. The pump that has been just sitting there (has a positive lead hot to it already) has been waiting for the switch to complete the ground allowing it to turn on.
The pump turns on, drawing alchy from the alchy tank, pushing it at 60 psi down a hose to a 'Y' connector. One side of the 'Y' goes to a solenoid that is closed at this moment, so the pressurized fluid goes where it can. It goes through a hose off the other side of the 'Y' to a nozzle mounted to the up-pipe.
2 Seconds later the boost has risen to say 18 psi, and a second hobbs switch that has been set to activate at this level, activates and closes the 2 ground wires attahed to it.
The solenoid that has been sitting there with a hot lead connected to it, now has the ground side of its circuit completed and can now do it's job.
Remember the 'Y' connector? The pump that is still running, has been able to flow fluid through only one side of the 'Y' because the solenoid on the other side has been closed up to this point. Now with the activation of the second Hobbs switch, the solenoid opens, and alchy flows through it, through a hose, and into the second nozzle attached to the up-pipe.
That's enough typing practice, I'm getting verrrrry sleeeeepy......
Hope this answers some questions.
