I have been thinking about how I can get rid of pooled water in the intake pipe during pre-compressor injection. One idea I thought of is creating a place for the water to pool, like bottle cap sized addition to the intake pipe that is lower than the compressor intake. Here you could place a small check valve that would close while you are WOT, but open when you let off the gas, allowing some of the pooled water to drain out.
I don't know what kind of check valve would open so easily that water could drain out, but I'm up for ideas. I also don't know for sure that there would be adaquate time between shifts and low enough suction in the intake pipe to allow the valve to open.
Here is my other idea.... You could use the vaccum from your throttle body to suck out the water from the pooling area (for lack of a better term) into a small catch can or something.
The only thing I worry about with the pooling area is that huge drops of water would be sucked out of it because of the high speed of the air in the intake tube. I think the depth of the pooling area would be the only way to reduce this. I also don't know if the pooling area would create a bunch of turbulence directly in front of the compressor. I guess it depends on its design.
I would appreciate any feedback that people have to offer.
