As we are discussing internal air flow, rediators and exhausts I think this picture will be good to compare the when there will actually be any updates on the car. The internal flow is important and Ferrari said before the season that some components are running more the limit with heat. So in that respect I think that revised mechanical design could be quit a challenge to place the different version of the original exhaust. Sauber C31 incorporated different style of exhaust while if we look at STR7 it has quite similar concpet to what F2012 is using now and we know that because of thier double floor they have more vertical position of rediators. The qestion is where will they channel cooling air if the original concept won't be used. We saw the "coke" engine cover at Chinese GP but this could be only update for Bahrain.
The picture Crucial posted earlier in the thread in my view would have to change the etire shape of sidepods. The downwash over the sodepods would have different effect. Event the current exhaust solution was not optimised in that way. But it acts as extracting cooling air so they let it in that way. It would be interesting to see a simulation of how the downwash over the channel on the sidepods interacts with current exhausts.
One notice on the drag issues. I think is interesting what is causing it. Could be the wings AoA or the entire bodywork. I belive they have to improve Cl/Cd ratio of the car.At last race they were also running shorter gear ratios.
Behind the inconsistent flow and temperature issues with tyres that "Acer" exhaust cause I also presume that thehy didn't direct as much flow down to the floor as they calculated. It would be no suprise to me if the current version that si pointing slightly inwards is actually gests pointed more downwards by the flow over the sidepods than the original position.
There is lot of discussion about aerodynamics issues but I also see that improvement on the mechanical side could be as important.
