The water tray on the ZL1 effectively reduce most of the heat extraction capability anyway. If someone provide a CAD file, I might run my own CFD runs just for fun...
Seems to me whether the reason is for heat extraction or downforce/avoidance of lift you still want the vent to exit into low pressure. I may never drive at 150+ mph, but if I ever do I'll want any front lift at least minimized, which comes right back to the same choice of hood.
