WAI commentary
Had breakfast with an older gent who specializes in the science and technology of combustion and currently builds alternative fuel power plants in places like China, the US, and Canada. I asked him about the WAI and whether he thought it would work, and if so how. He says that the heat-expanded air would cause, in effect a richer mixture, though no extra fuel unless the rate of inject were separately adjusted. The WAI certainly does not produce a leaner burn (many of you probably already know that). Any FE gains he thought would have to be produced by heat energy recovery in the hot air being re-introduced to the engine from the manifold. He thought the gains would be minimal (which is true, by my test anyway). But adjusting the flow of fuel would create further gains. Has anyone done that in addition to the WAI itself?

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
