the more i look at this picture the more i wonder!

why the hell dont they use black screws?!!!

They do, they're just less matte than the area around them.

[marcush.]

so why do teams reiterate that track testing is useless and not giving any benefit?
Smokescreen anyone?

Sure I have the opinion that you cannot simulate or windtunneltest to the fine resolution needed and get perfect correlation without having acces to fudge factors -and you need those created from real world full scale testing ..but no means of measuring apart from load cell outputs, stopwatch and driver comment ..a bit too much of indirect proof of the pudding in my book.

Indeed the F2012 has the curved strake on the floor & the silver one too like at Mugello.

why is one silver other not?

heat resistance difference?

It's exactly like what Ferrari used in Mugello. They were obviously simulating this exhaust solution on the 1st day in Mugello. But yes the silver tunring vane should see more exhaust gasses than the curved black strake

They don't – the teams who happened to have the fastest car at the time did – because they didn't want the others to be able to gain from testing.

This pic from Autosprint.com shows what appears to be a small hot air exit just above the exhaust exit (between this and the body panel); this would be in line with what I mentioned in my previous post as the differential between this jet of air and the one flowing on top would help directing the gasses as well...



Hot air exit can also be clearly seen at the inner side.

Some informed people told me that the new exhaust solution was tested in both wind tunnels - in Maranello and Cologne (ex-Toyota).

so we have 3 different air stream:

fast air above bodywork
slow air from car coolig
fast exhaust

Can this help to direct/seal exhaust by creating a couple of counter rotating vortex ?

My engineering-scouter just exploted with that. Clearly over 9000.

Now seriously, I think it could be true, but that they are also conditioned by their original cooling itinerary. So perhaps they are just forced to do that. Or perhaps a little bit of the two possibilities...

These exhausts aren't there for aerodynamics right? Looks to me this is all about managing tyre temperature rather than using the exhaust flow for aerodynamics.

well...i gotta say u r mistaken my friend..

but how?

i tought wind tunnel models dont have working engines?

They don't, not in the Maranello or old Toyota tunnel. Teams attempt to simulate the exhaust in the wind tunnel, but it doesn't compare to what actually happens on the track.

The point is wind tunnel simulation will be helpful but only to a point. CFD would probably yield better more accurate results, but the tunnel would help. The main thing is that Ferrari has already simulated this exhaust on track. So they obviously feel comfortable with implementing it.

Here is a good comparsion from the two different exhaust system:
