just a dumb question.... can you put a small tunnel (gap op aprox. 2mm) to the floor so this way the air can still flow through to the back and stop the porpoising?
hope its understandable what i mean, i am bad at drawing so no other way to explain
A 2mm groove wont be enough.
There is already a big tunnel formed in the floor as you can see, so the floors cannot physically bottom out like a flat bottomed car. Air does still flow under them when they bottom. It's just that the teams want a certain pressure to be achieved and maintained instead of that sudden increase when it "chokes."
I think the width of the tunnel is restricted by the regulations, so teams have made those edge flaps to allow some relief when the car bottoms out. I am not sure how they work... But I suppose at a certain suction level further decrease is suction is capped, and air is allowed to escape/ more to enter? (i dont
Know yet) before/after the throat.
Think of it almost like a flywheel, expansion tank, or a band pass filter... You pay the expense of capping the maximum suction of the floor, but you now have a stable peak.
