Ferrari exhaust outlets configuration from Launch to Hungary
Ferrari , Launch – Periscope exhausts
Ferrari initially started the season with periscope exhausts while later at Valencia(following Red Bull’s RB6 path ) presented a new exhaust system located lower , close to the floor and inside the rear tyres zone . This new exhaust system configuration called EBD (Exhaust Blown Diffuser ) helps to energize the rear diffuser with hot exhaust emissions boosting downforce production .
Valencia – standard version
At Silverstone and during free testing sessions Ferrari had its EBD pipes cut off at their end to permit a stronger interaction of the hot exhaust gases with the rear side airflow coming around the sidepods bottoms . This configuration was replaced by a new one with elongated pipes towards the rear end to blow hot emissions stronger to the diffuser . The later revision remained for the race .
Silverstone , tested – cut off version
Both specs , the cut off and the elongated pipes configuration , can be considered to be extremities of the original design ( for less and stronger interaction with the diffuser respectively ) .
Silverstone , race – elongated version
Another modification was the addition of a heat protective floor element behind the exhaust outlets covering the rear wheel – car body floor inner zone .
Hockenheim , race – new elongated version
At Hockenheim a new elongated version with cut off inner surface was presented . During free runs the team tested also a modified rear floor configuration with heat metallic covers behind the exhaust outlet but the use of them was later regarded unnecessary and were removed for race to save weight in favor of ballast . Nevertheless despite the removal of the metal covers the rear floor gained an extra thick lighter carbon cover .
