But a fixed amount of fuel does not equal a fixed power! It closer approximates a fixed torque. But given the influence of that on the drag calculation (^2 rather than ^3), the basic approach should still be valid (on diesels anyway).
(But I am still struggling to understand how that helps on engine modifications, as you suggested.)
