Exhaust pipes remain one of the last bastions of hand fabricated metallic parts on an F1 (along with radiators). While we can all marvel at the metal shaping and immaculate welding, the exhaust is also a key tuning aids for the engine and highly influential on aerodynamics too. So here’s a quick dive into some of the unseen technicalities and details of the F1 exhaust from the normally aspirated V8 era.
Since 2010 this blog has covered a lot about exhaust blown Diffuser (EBD) technology, especially in the latter years when it was allowed in F1, with the use of the Coanda effect. Now three years on, some of the manufacturing processes that allowed such rapid development of EBD’s can be revealed, especially with the use of 3D printed titanium parts. Here we have a printed titanium coanda duct from the Marussia Team.
Last year I was able to acquire a piece of the PS01B and one of the last developments Brunner and his team put on the Minardi, the blown diffuser. Blown diffusers were not new; indeed they had gone out of fashion that very year, as the periscope design was the trend.
Toro Rosso have released a youtube video of a complete factory tour. Both informative and in depth, the video shows us some detail of the car we do not usually get to see.
