How, for example, would the long inlet of the tail-engine on an MD-11 or an L-1011 affect its thrust production/performance, if at all?

I am not well versed in fluid dynamics, so any insight on this would be helpful. I wouldn't be surprised if the effect of the aforementioned distance is negligible, as the airflow would not seem to be disrupted. Nonetheless, this piques my curiosity.
