The height could be well be the same as last years, now check and see if that top inlet is still in the same place?Vanja #66 wrote: ↑02 Mar 2018, 00:44Mirror brackets, in my opinion, most likely guide the air towards that top inlet. I've written already a bit on mirrors here, but I'll gladly add to it.

This is the first mirror bracket design in 2017, and as far as I remember, only used in winter testing. Throughout the season, Ferrari used the same bracket design as current one. Design on picture is lifting the mirrors as high up as possible and is using additional flap to get some of the air flowing on the inner side of mirror bracket (closer to the driver) to the top inlet. Current design is doing that as well, but with a curved design they are using more air for less drag (slots induce drag, that flap in launch spec design caused a vortex which induced drag as well) and have lowered the mirrors for better visibility (look how far down the list their primary function lies).
As for current mirror fairing design, it's there to reduce drag. If they wanted to move the air from the mirror to the inlet with this design, they'd lower the mirrors even more. Mirror position (in terms of height) hasn't changed from last year's final design. Last year mirrors weren't flow-trough, ergo - they were a problem, they caused turbulence (as ever) and they needed to be as high as possible not to obstruct air flow, but as low as possible not to hinder driver visibility even further.
To end this with something basic - you don't want turbulent air in your radiator intake and even if you did, you can't make it go to the high pressure zone of top inlet.
Some things are simple, some are not and not everything in F1 is complicated.
I too believe this is to work "side by side" with the top sidepod inlet but reading what you wrote also makes 3 more things come to my mind:Sieper wrote: ↑02 Mar 2018, 17:11the top inlet and the mirror are in the exact same plane when viewed from above (as opposed to last year). If the mirror was not intended to play any role in getting air towards the inlet then why is that?
I too think it will not be powerful enough to bend the air at higher speeds (if at all) but an interesting idea was posed (forgot by whom) that at lower speeds it might be able to bend the air a bit better.
If it is just about drag reduction, then why make the mirror essentially a bit bigger (to accommodate for the slots above and below the mirror glass) this will increase total front facing surface. Now it might help as it will likely pull the air through at higher speeds possibly decreasing overall drag.
No need to check anything, already did it a few days ago.
To continue with this discussion is pointless, in my view. Those who believe mirror fairings are there to bend the airflow into top inlets (in spite of laws of aerodynamics) have the right to do so, but please don't bring down the level of discussion with (more) pointless arguments.Vanja #66 wrote: ↑24 Feb 2018, 01:13
4) Mirrors are a bit further back (and as low as final-spec in 2017), but overall at the same distance from top side pod inlet as last year [ADDED: Just to clarify, but I honestly don't see how anyone can see anything else on this picture - the trailing edges of mirror fairings are at the same longitudinal distance from leading edges of top inlets on both cars. The lateral distance has slightly changed at the dirsta race in 2017, as well as height and was the same as now.]. Unlike Scarbs, I'm not sure they are used to guide the air down (although that would be very very clever), as I'll explain and show further down this text.

13) Different position of mirrors, very similar to final spec in 2017. More on them later down, there's a better picture to explain my thoughts.

On this picture you can see that inside surface of mirrors seems symmetrical. This would indicate only drag reduction for mirrors, in ways discussed on this thread. I honestly don't see it as an attempt to guide the air down towards the top side pod inlet, no matter how cool that would be. I'd like to see it happen, I just don't see it now.
So both are virtually in the same place as last years car, and the distance relevant to each other?Vanja #66 wrote: ↑02 Mar 2018, 19:45No need to check anything, already did it a few days ago.

It was people a lot brighter than i am that came up with the concept i believe, i just happen to agree.paddyf1 wrote: ↑02 Mar 2018, 22:00So both are virtually in the same place as last years car, and the distance relevant to each other?Vanja #66 wrote: ↑02 Mar 2018, 19:45No need to check anything, already did it a few days ago.
