Yes, draw enhancing front diffuser, but if that hole was an exhaust, you would be enhancing the flow way too late. When that flow from the front diffuser reaches the edge of the floor (on the side), it spins around it and gets sucked under the floor, in front of the rear tire, right into the diffuser. Blowing air under that angle at that rotating flow is just going to disturb it and you will be effectively shutting down the floor. One could argue that it may be a good thing to disturb the feed under the floor when on throttle, so you reduce technically down force on the straights, but that also makes it tricky if you want to do some throttle variations in the middle of fast corners, when you do need continuous/predictable flow into the diffuser. But if someone figures out how to create the exhaust in a way that energizes further the rotation and also does not abruptly change things upon backing up the throttle, I would love to see how that works.
