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?
