And you would want then to figure what percentage this is of the power your engine generates in order to accelerate your vehicle or hold steady state, no? If at freeways speeds you only needed say 30hp but your alt is drawing off 1.5 or more, you have maybe at least 5% going to power generation instead of vehicular mobility, no?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. 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.
