Turn it on with the hand, turn it off via the airbox pressure????? Random thought, dangerous if you accidently turn it on through a full throttle corner though.tok-tokkie wrote:The TV I saw of Friday practice when Webber's engine blew showed he has sealing foam on the back of his left glove for sealing the control port. Just like Ferrari. It is not an automatic system. The big difference compared to McLaren is the normal flow when full downforce is wanted is in the lower tube below the wing whereas on McLaren that tube is down to the bridge wing level.
How could their F duct possibly be activated depending on throttle opening (= airbox pressure)? Turn 8 is MAXIMUM downforce corner but it is also full throttle. Down the straight is MINIMUM downforce but again it is maximum throttle.
