Thanks Larry for the "real world" experience.
It's just as I would like, move the compressor effectiveness back (left) into a more efficient island of the compressor map. I'll compress not necessarily more air, but compress it more easily with less intoduction of heat.
What effect the water will have on impeller speed questionable. While theoretically more viscous, the water mist may evaporate so quickly at the impeller to essentially behave as a gas, albeit a more dense gas. I believe it will slow the impeller to some degree, another benefit that I think Saabtuner mentioned.
I'm going to try to get WI volume up to 20% of fuel, such that when shunting 1/3 to the turbo we sending a bit more water/methanol through the turbo, around 0.7% by air mass. Or I'll shunt a larger percentage than 1/3. I'll have to see what works best.
We'll see how it works around mid-Oct.
