Water Injection: Anyone tried on TD?
I found some very interesting links. One even states that someone who ran some formal sounding tests got a 20.8% increase in power output.
Here's some links: link1 link2 link3 Even if not for power increases, I've heard that the water injection process does wonders for carbon removal and engine cooling. Also heard that years ago, GM or Ford or whoever even used to sell WI systems on standard street cars.

Water injection on a naturally aspirated diesel wouldn't really do much. However, it would make a difference on a turbodiesel. The only thing it would do is lower the intake air charge temp and thus make it a little denser. Combine this with a tweak to the fuel enrichment, and you'll notice a small gain in power/torque.
You might get away with a very small bump in timing advance, because it's logical to assume that the cooler denser intake air charge will slightly delay the start of combustion. Also, you'd probably notice a little more consistent performance... your car would not become so sluggish on a really hot day. The water vapor would also "steam clean" the engine a bit... so if you pulled the head after prolonged use, you'd be treated to an unusually clean set of diesel combustion chambers. -Joe |

So for turbo diesels, the WI is all good?
One thing I wonder about is having to run the water through the turbine and fear that this might cause some sort of longer term corrosion.

If I were you, I'd inject the water *after* the turbocharger. I'd also make sure you were using a high quality WI kit that atomizes the water really well, don't use the $10 JC Whitney special
Don't expect monster power/torque gains... it will make a difference, but I doubt it would be much more than 5-8bhp when combined with appropriate fuel and timing tweaks. -Joe |
