New water injection set-up

He posted drawings of that on here over a year ago. Injecting water preturbo is hard on the wheel. Can you say erosion! Tractor guys do it to billet wheels and they still wear. Anything that hits the wheel, hits it hard as edge speeds can easily exceed the speed of sound.

Dunno. Seems like a turbo impeller going 100,000 RPM will pretty much atomize the water even if it was just a stream. Perhaps makes more sense to have it after the turbo.
When I was testing the Snow system on a dyno, no HP gain was seen, and 150? deg drop in EGT's. Power comes from the alcohol.
Looks cool though.

I dunno, has anyone ELSE tried small "fog" size droplets preturbo? i don't recall it if it was ever done before
I've sprayed water pre-turbo, and didn't see any problems. And I've sprayed post-turbo as well. The intent of the water is to cool the air. The hotter the air is, the more cooling effect is possible. My current thought is to let the intercooler do it's job first, then spray water to cool the air further.
I'm still not sure it really has the effect I think it does. Even with lower EGT's on the gauge, I've still hurt turbines with the water on, and melted pistons.

Looks like the nozzles thread together. Do they get peened or something? Not sure I like the idea of parts that could fall off and get sucked into the turbo
I remember it too. IIRC, the pre-turbo trick as said it "Fog". Much finer droplets. Likly it would cool better too? My only concern, what if a fog nozzle came loose and this is pre-turbo = big boom!
But it theres no way they could come out, i'd try it Very nicly made part!
Ahhh, Paul beat me to it!

It would make the air more dense and result in more boost, but I don't understand how this would work with a vvt turbo.....wouldnt the vanes just open more to limit the boost
not sure bout the vvt turbo but when installing mine post turbo and post intercooler i noticed around a five psi jump in my boost pressure like previously stated denser air either way...
Call Columbus Diesel Supply. This is nothing new by any stretch of the imagination.
I was snooping around at DP as there is lots of water/meth info there and found a dyno sheet with 50/50 mix that lotsofmiles did-quite impressive.

Water alone likely won't make power from what I have read and researched, but it will cool things off-which is what I would be more interested in. But with the meth, the numbers are surprisingly impressive IMO.
