This has been common belief in Pantera Land for many years now, but some actual testing recently done by Panteras NW member Matt seems to disprove this belief.
He has run several various tests, various speeds, with the stock A/C condenser/fan unit in place, and without them in place.
Here is a link to one of his Youtube videos. You can find links to the others at this link, also.
Matt posted all this, and we had quite the discussion, over at the POCA forum.
Keeping current on both forums, I believe, is well worth the additional time.
This is with fan sucking in (as stock). Note the plastic flaps are uniformly being held tight to the inlet grill.
