it might, tony- it's a dry sump system with eight (thats right, eight) scavenge pumps placed throughout the engine. . . . even on the heads. . . . but i wonder how the fuel is pumped- if the pump is on the bottom of the tank like a street car, then obviously that would be a problem. . .. and how long can someone drive upside down? a minute? two? humans dont make any downforce. lol.

and just to be a total prick, there is a difference between downforce and suction .. . . . the effect may be generally the same, but the cause is very different.
