Ducktail on Ice for 991.2...

So does this mean "Duck + Paint to Sample" now= $1 million?????

At low speeds without the spoiler up there apparently is still enough of a pressure differential between the top and bottom back end of the car to have air flow through the grills into the intercooler and out the bumper exits.
If the ducktail provides some downforce by air pressing on the spoiler then I assume that there must be a pressure increase in front of the ducktail. This higher pressure should be beneficial in forcing air through the grill and eventually into the air cooler.
I'm likely wrong if the ducktail is increasing the net downforce by reducing lift due to airflow over the ducktail as opposed to actually producing more downward force.
I would like to see some theory on how the ducktail performs aerodynamically - maybe something I need to look up somewhere.

Yeah I'm with you on this one.

The new spoiler has a much steeper angle of attack with cooling ducts in the set up to assist in ramming air into the intercoolers at speed. No chance of a ducktail for this reason on the turbo motored 991.2....
