It's a long shot, but I have to imagine that it's having some effect with such a low Cd on a high-downforce design.

Christ,the intake may have behaved as a low performance suction slot,helping to vacuum the boundary layer onto the roof.Hard to verify without the car.Porsche does have their own windtunnel and while 3rd-party modifications have crashed,Porsche's designs have faired well in competition and I bet they really sweated the details on the 917.
