If there is air being fed through the fin to the rear wing it's along this line that I'd expect it to be coming out. What do people think?
If that slot is pumping air, the flow rate must be tiny! Considering the size of the auxiliary inlet, the back pressures must be huge (would this maybe stall the flow into the airbox???). This could, of course, explain why the inlet size has been reduced.
Still, I think the flow viz had simply got stuck on the ridge through some circulation and the picture on the right would make me think the slot is not blowing at all or it would have blown the flow viz paint off. The picture on the left could show the slot blowing, but it's a bit inconclusive.
