    Nice start to your blog Bar555. While on the subject of exhaust driven diffusers it would be nice if we could tie down the exact benefits of such a layout. Is it purely to isolate the diffuser flow from tire turbulence, or is it just about introducing more highly charged airflow into/over the dead flow areas of the diffuser box.

    For example, Red Bull ports some of the exhaust flow into sections of it’s diffuser ports. Do McLaren and Ferrari do the same? I haven’t seen any pics that address this point.

    Also it seems that McLaren have gone to great extents to overrun the engine during braking to keep the exhaust pressures up. Everyone speculated that RB have been doing this since inception, though upon hearing the sound of the McLaren after they implemented this I have to wonder whether Red Bull are in fact doing this, at least on the scale that McLaren are.

      Thanks BreezyRacer .
      Mc Laren and Ferrari may launched their own EBD version but that does not mean that their design is copied directly from RB6 . On the contrary they took the whole concept and adjusted it to their car’s special characteristics . Red Bull RB6 as you said , features a small clever duct at the side diffuser wall to permit hot exhaust gases intrude inside the second diffuser’s deck , energizing the airflow and boosting its performance . Mc Laren and Ferrari cars lack a similar duct and blow their exhaust towards the outer side diffuser section . Initially Ferrari tried short exhaust pipes and later longer . Nevertheless at Belgium Ferrari reverted back to short pipes . Mc Laren tried also some versions of its own system . Why is that ? Because Red Bull had plenty of time to test the EBD during winter testing ( even though there were some minor updates to RB6 EBD ) , a luxury both Ferrari and Mc Laren did not have . So they had to experiment on the system on race conditions and find out which configuration suits better to their needs , which btw may differ from race to race .

      Another crucial fact is that each configuration has a different heat impact on the rear bodywork and adding too many metal heat protective plates and covers would effect the car weight balance . So my opinion is that Ferrari and Mc Laren concluded to the best balanced configuration between extra rear downforce ( depending on pipe length and track characteristics ) and car’s balance .

      As regards engine mapping I have to say that both Ferrari ( since Hockenheim ) and Mc Laren ( Hamilton used it at Belgium Q3 ) are running a special one , regarding ignition , to keep the exhaust pressures up and gain downforce at slow corners .

      Thanks again for dropping by and I hope to enjoy our company here
