Porpoising:
1) Is not that related to the surface the car run on. It's 90% an aerodynamic issue
2) Is caused by the flow choking at the back of the car, t-tray has minimum effect
Also damping the porpoising in a generic sense is not the solution. It is an instability, not just a bump on the road: damping will not fix the issue, it will at best limit it, but compromising the optimal damping required by the mechanics of the car.
Surely the porpoising is to do with the vortices in the tunnels bursting when the floor gets too close to the ground
Watching the Redbull today, it was slightly porpoising on almost all the straights. I think the forces above the car also contribute to the bouncing. I'm thinking the porpoising gets amplified because of the natural springiness of the suspension.
Oh for sure the forces above the car cobtirbute to car lowering to the point where the underfloor flow breaks down.
They cut the bottom of the inner moat strake didnt they, can only assume that was an attempt to alter position/strength of the vortex that would be rolled up on the inboard side of it.
