soaker hose
 

I'm not fond of the soaker hose idea, --- seems to be too much complication, and an absolute gurantee that you would end up with liquid water running down the bottom center of the duct. By the time you get that long tube supported so it does not fatigue fracture and go through the turbo I think your drag losses in the intake would go sky high.

At this point I think some controlled tests on a test rig would give us more useful info in 2 days than we could glean from months of brain storming.

I just need some time to cobble together something that will allow some pictures and measurements to be made.

New job it keeping me busy. ;)

Oh well, a revelation for me alone then, I guess.

Hope I was clear. Each pseudo nozzle in the SS line would be much smaller flow than any w/i nozzle presently marketed. Large droplets would wet the wall, small mass droplets entrain in the stream. It has the advantage of saturating using all means, given the short residence time before turbo.

Not sure why a SS line would be in danger of coming loose. Of course, this is unconventional, out of the box thinking. That is, no doubt where the solution is for such a challenge.

Perhaps you have seen the loops that are fastened to high speed fans at football games, for quick cooling on the sidelines. I'll find one and post it.

wow interesting read. some thoughts i had that im not sure were covered though..

i think there is always a step from turbo inlet pipe to compressor housing (unless the rubber pipe flares out just at the compressor inlet).

if im running one pump and 2 hsv, what happens with the pressure difference at the nozzels?
say i start injecting the main jet (after the intercooler) at 18psi and the pre-compressor jet at 23psi. engine running a max of 28psi.

would the water be more likely to travel to the compressor jet as there may be a vacuum in front of that one and +23psi in front of the main jet?

Any progress Larry? Or anyone else?

Larry I was wondering what size nozzle you are running pre-compressor. If I remember correctly you have a Shurflo pump, correct?

Do you have post-turbo injection as well?

Drew I have also thought about what will happen when I run a dual stage set-up (1 pre, 1 post compressor) when I change to a pre-compressor injection nozzle. I wonder if the Shurflo pump can maintain pressure so the nozzles continue to atomize correctly. I know lowering the pressure of the system by adding a second nozzle decreases the amount that the nozzles each flow, but what is the effect on atomization?

I currently run a dual-stage post-turbo WI setup with no problems. I just worry about changes to the atomization when I move one of the nozzles to spray in front of my soon to be new turbo :? .

I have a turbo with turbine wheel damage from a manifold cracking and throwing chunks downstream, so I am willing to sacrifice it in the name of science :wink: . The only problem is that I am continuing my year long travels in SE Asia and will not return to Colorado until October 2005, so we will have to wait until then.

i was thinking of maybe adding one of those inline check valves in the pre-comp line.

something along the lines of if i got 15+ psi after the intercooler, i could try and balance the flow between the 2 jets with a 15psi valve at the compressor.

although just read aquamist's website..

maybe thats what your supposed to do anyway.

I would like to see a 70-90 psi crack pressure in a check valve. That would help prevent inneficient atomization for the critical pre-comp stage.

...or a solenoid run by a presssure switch on the water line, etc...

setup
 

Well at the moment I'm getting ready to re-configure things. My old setup was pre-compressor only and a 3 to a 4 gal/min nozzle. That was too much water in retrospect so I decided to rebuild the system.

I will be adding pre-throttle body nozzles and reducing the pre-compressor nozzle size probably to a 2 gal/hr or a 1 gal/hr rate.

My system uses a shurflo 100 psi pump and a shurflo 24 fluid ounce accumulator (pn 181-203) and the trigger solenoid sits within inches of the nozzle, so the turn on time is very short, with a large accumulator at 80-90 psi feeding the solenoid.

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.
