It's always a compromise. Ferrari and Redbull sacrificed some of their front wing load since pre-season. I do think it would reduce porpoising as it's strongly related to peak downforce stalling the floor. That being said, that would be fixing the symptoms, not tackling the root cause. Mercedes ran a softer suspension since the early spec in Barcelona tests. I thought it was a setup issue, but clearly they have some ground to cover in this department. If they can prevent it from happening in the first place, that means less compromises.TimW wrote: ↑31 Mar 2022, 14:09I don't think this is true. The downforce from the wings is stable, the underfloor aero causes the instability. So backing off the wing downforce (without increasing ride height) does not help for the porpoising. Removing the underfloor downforce would.Stu wrote: ↑31 Mar 2022, 08:07I had been thinking this too (very high downforce floor), but if this were the case the solution to the porpoising issue would be to ‘back off’ on both front and rear wings (to the point that are only used to ‘hit the numbers’ and get balance). The suspension would then get a better time of it (and the porpoising would be reduced).
This doesn't explain why they literally launched the car with barn door/park bench wings though.
Not sure where you are getting your conclusion from.atanatizante wrote: ↑31 Mar 2022, 21:53So you can stall the Venturi tunnels just to diminish the porpoiseing after all, it seems:

and what about the porpoising in the corners? What good is a stalled floor then?GrizzleBoy wrote: ↑31 Mar 2022, 22:59I haven't watched the video, but I've had the same idea a couple pages back.matteosc wrote: ↑31 Mar 2022, 22:10Not sure where you are getting your conclusion from.atanatizante wrote: ↑31 Mar 2022, 21:53So you can stall the Venturi tunnels just to diminish the porpoiseing after all, it seems:
If you can shape your front/mid aero so that at very high-speed the floor stalls and stops producing suction then porpoising should disappear.
Basically instead of trying to stabilise the strong suction of the floor on the straights, it would surely make more sense to actually try and shed the strong suction instead.
So imo I think people want merc to resolve the wrong half of the porpoising issue.
I do not think that this is feasible in practice. Stalling the floor at a specific speed requires extremely precise control of the ground clearance, contrary to what happens to the aerodynamic of the top of the car. A minimum change in the car height significantly changes the speed of the air under the floor, so that you risk to stall the floor at every bump.GrizzleBoy wrote: ↑31 Mar 2022, 22:59I haven't watched the video, but I've had the same idea a couple pages back.matteosc wrote: ↑31 Mar 2022, 22:10Not sure where you are getting your conclusion from.atanatizante wrote: ↑31 Mar 2022, 21:53So you can stall the Venturi tunnels just to diminish the porpoiseing after all, it seems:

It's a launch car, you probably want to run it in high downforce mode initially to make sure its all there. Taking downforce off is easy, adding it on is hard.GrizzleBoy wrote: ↑31 Mar 2022, 20:27This doesn't explain why they literally launched the car with barn door/park bench wings though.
They decided to run these wings before anyone even knew porpoising was a thing, during the design phase.
