David Sanchez and Enrico Cardile on the SF90 had thought of clearing the entire area above the engine by bringing all the radiators and exchangers into the bellies, to free the hood and reduce the resistance to advancement, while Mercedes and Red Bull have maintained a high part of the cooling system, looking for slimmer sides.
The facts indicate that they were right: on the SF1000 the cooling system was optimized to the point that the speed of the passage of air was reduced with four radiators packed one on top of the other, creating an aerodynamic locking that made the Rossa a sort of "wall", unable to reach high maximum speeds.
Basically, the hot air is not extracted quickly from the sides and harmful turbulences are generated which can go to touch the exhausts which, on the other hand, must be as close as possible to the body of the engine, in order to leave a large vent channel in the back of the car body.
The most attentive will not have missed that in Austria the terminal part of the bellies had been cut to enlarge the outlets of hot air in spite of a worse aerodynamic efficiency. What did they decide to do in Maranello? They probably decided to bring a radiant element over the power unit, freeing the sides.
It cannot be excluded that in part the problem may have been caused also by the dirty air that could get into the radiator vents. The front wheel, in fact, generates harmful turbulences that the barge boards and flow deviators have the task of deviating precisely to move them away from the body of the car and from the possibility that they can be channeled into the mouths of the radiators or under the bottom, towards the rear diffuser .
