Exhaust Blown Diffusers under 2014 regulations.

Post

Is it possible to have a portion of the exhaust routed to the under body to heat the air flow there and then exit at the central common exhaust under the 2014 regulations. Hence there will be more energy in the air exiting the diffuser and probably more downforce created.

This might bring a string of overheating issues if not handled carefully but looks like a possibility to my eye as I looked at the text.

No.

How can you blow the diffuser and then return the exhaust to the exhaust system?

i think he's meaning to direct air through the sidepods and create a tunnel where air gets heated by the 'walls' of the exhaust, then have these tunnels direct air to the floor.

the answer is yes, you can heat air, but NO, it will be in no way hot enough to produce anything of value.EBD is over this year.

Definitely! .

...When the engine blows up!

I don't think there will be any downforce creation per say. Maybe up-force destruction perhaps?

Definitely..no.
1: exhaust gasses after passing through turbine lost a lot of energy
2: No leaks allowed in the exhaust ducts, all the gasses have to exit from one tailpipe
3: the only way to use them is making some tricks about monkey seat, but with more drawbacks than benefits as we know from an interview of a force india engineer (called Green i suppose). So at the moment it's not a point of interest for teams IMHO.

It would be undesireable to heat the air with the exhaust headers, since that cols the exhaust and lowers the amount of energy that can be recovered by the turbine/MGU-H.

The pictures of teh Renault PU show the headers shrouded to keep the heat in the exhaust.
