Good show mintos! But it from a theoritical point of view (too much unpracticed engineering here) it is highly possible to create a small pressure difference with in the intake that will enable faster airflow. (and the answer may not lie in an inline fan, i'm still pondering it) but the problem is that without building this sucker from scratch and cutomizing a control system for it based on speed and engine output (revs) it will only benefit the engine for a very narrow speed and rpm range. And then deciding whether or not this is feasible, and at the end of the day, its just a bit of fun for a project.
