| OK, I'm sure I'm about to open up a large can of worms here, but it seems to me that a really really good water injection kit would include the following, most of which can be bought at my local commercial agricultrual supply wearhouse. 1) Surflo pump (100 PSI)
2) Adjustable accumulator tank to maintain constant pressure and regulate flow.
3) Adustable pressure switch.
4) MAP sensor.
5) Stainless water injection nozzles.
6) High speed valve for metered pulsed injection of water.
7) Cutoff solenoid valve.
8) Hoses, clamps, etc. ..and the last and most critical part... 9) One of many different programmable micro processors with analog and digital inputs and outputs, etc. This is the tricky part because you'll either want to trigger off of MAFor injector pulse to determine duty cycle and therefore how much water to inject. Additionally, you'll need to use a MAP sensor as an input into your program to compensate for the additional water needed just to account for manifold boost pressure. Now items 1 through 8 can be bought for about $300. The kits I've seen offered here don't even use a high speed valve but just rely on a pressure switch to turn the pump on or off which doesn't allow you to custom map for manifold pressure and actual air or fuel flow. The sysems that actually do this like Aquamist are really expensive. So since I've done tons of embedded programming in my 15 years as a software engineer, it seems to me that if I want a system like this with true 3-d mapping, I'm just going to have to build it. Of course the time and energy to do something like this would probably far exceed the cost of just popping for a full 3-d Aquamist solution. I suspect as simple as the concept is and being comfortable with embedded systems, the actual reality would probably be quite time consuming. Sigh!
