Ferrari F2012 – Frenzy exhaust evolution
From the very early testing, Ferrari understood that one of the weak spots of the F2012 was the exhausts. Due to new 2012 regulations all teams forced to move away the exhaust outlets from the floor level .However the ardent desire to take advantage of the exhaust blown effect yet remained strong and thus Ferrari designed the exhausts to blow through the zone between the rear wing endplates and the wheel . The hot emissions bent progressively downwards as they travel to the rear of the car and seal the diffuser sides improving its efficiency . Another interesting thing is the common bodywork opening for exhaust pipes and radiators cooling exit .
At least nine different configurations tested from Launch to Melbourne and are all summarized in the illustration above . The launch exhaust abandoned very quickly because it caused tarnished dots on the bodywork around the exhaust outlets,indicating overheating .Since then the exhaust zone suffered several changes before Melbourne . The revisions that took place include :
– Horizontally cut exhaust pipes ( specs B, C and D )
– Cuts on the bodywork ( specs C, D, E, F, G and H ) to both improve cooling and the strengthen the downwash effect of the emissions
– Carbon heat protective patches on the bodywork ( specs C, D, F, G, H and I )
– Shifting of the exhaust outlet angle initially upwards and then inwards
First steps in exhausts evolution obliged the team to even place carbon heat shields on the bottom outer surface of the rear wing endplates for protection. Finally numerous thermometer stickers placed on the suspension wishbones and car body to investigate overheating issues displayed by each different exhaust system tested.
The target for Ferrari with this continuous and frenzy exhaust evolution was cooling improvement, car protection from heat and rear down-force gains .Nevertheless the quest of extra more never fades away .
