Well Adrian, what a great graph. I see you address some of the caveats here. I'm glad you posted it on NASIOC as well. Those guys are harsh on WI.

As I said on NASIOC, I find the difference in AFR optimum with WI and w/out very interesting. With it's 12.5:1 and without 9:1--an amazing difference. It really changes the way you think about tuning with WI--less fuel is the way to go, and 12.5 seems the magic number even with the crappy fuel that they were probably using in 1944.

Do they state the octane of the gas in that experiment?

I wish they had done the same experiment with less water than 60% of fuel, something not many are willing to haul around in our cars.

I also wonder if the experiment was performed at mulitple RPMs or just one?

Also, where was the water injected? Pre-turbo? Pre-throttle body? In cylinder? Me thinks it was pre-turbo.
