Looks like Lotus will not be running "the device" this weekend at SPA. I was really hoping to see it in action finally.

And you know this how?

I think they should try at least with GRO car. Other teams are also working on that solution and there is possibility they will not take advantage form it, because others will have that on their cars soon.

This may have been suggested before, but how about this? The rear wing is set up to provide the required downforce, with air being blown through the small upper tube. In other words, situation normal.
Now, inside the engine cover is a spring loaded flap that is tensioned to move when a certain airpressure (governed by speed) is reached. This closes over the upper duct, alowing the wing to stall and produce less drag. The air is now diverted to the larger exit, operating at a lower pressure, and dumping the air into a low pressure area.

Simple and passive.

Moveable aero device. Not permitted.

They really ought to just run it now or forget it, they're wasting far too much time worrying about testing and setting it up that probably could have been better spent elsewhere after all this will-they-won't-they debacle.

I agree.

It might simply not work in the rain.

one race distance is a lot of testing miles...

But the biggest problems is that they can't completely remove the "device" from their cars because of front intake holes.They can disconect the tubes, but because of rules they must leave closed intakes.That only creates drag, but nothing positive.This would be Kimi's third race in a row runing that system and gaining no benefits.

Depends if water getting into the nose scoop will adversely affect the airflow and stop the fluidic switch from working.

I was thinking the same thing, and with races passing by without using it (and possibly losing points not benefitting of the possible advantage it gives them), it would become a useless investment for the last races, or it might be too late to use it as it will be banned for next year. But then again, someone said that the device might avoid the rules that ban DDRS.

Then they should abandon it now, if 3gp's don't have good enough conditions right through practice to race to even get some data back from it, then they'll never have a hope of setting it up in variable conditions on a race weekend, it'll only ever get used at one or two circuits, and they'll never be certain if they've set it right.

If the flap is inside the airbox, it would not be considered an aero device. Just as a fluidic device is not called an aero device.
