That's not really how it works. The 25 units of power for 55 mph can work out, but the 2200 rpm is not to get 25 units of power, but to get 55 mph. For each rpm, there is a certain amount of power available. Actual power will vary depending mostly on the throttle plate openning.
We've already discussed WAIs and CAIs in plenty of threads to great lenghts. You might find the information you are seeking in those threads. If you have any unanswered questions or feel like commenting on some points please do so and it'll be a pleasure to continue the discussion. But I don't think we need to go over this all over again from the beginning.
