We already have an exhaust blown diffuser thread that is discussing this ban viewtopic.php?f=1&t=10055

What the hell dude, the link you posted is this exact same thread

just to muddy the waters a bit more..

#F1 One team source tells me that Renault's exhaust advantage stems from the engine's use of a butterfly rather than barrel throttle

#F1 Which apparently means that a 50% opening actually equates to 68% - the number I gave earlier today. It's getting complicated...

At least we are retaining our sense of humour,

So Renault allowed 50% off throttle for reliability. As Whitmarsh asked, "If my brakes are marginal, can I run 100kg lighter? No."

Good article from Andrew Benson http://www.bbc.co.uk/blogs/andrewbenson ... s_lat.html
, but a quick run down : lots of arguments today, mercedes cars ran 50% throttle illegally during practice. A big meeting is going on now apparently

Well, seems like a plan to stir the FOTA once again otherwise it is the stupidest decision imaginable.

I don't think so, its just plain incompetence by the FIA.

Scarbs has posted to his blog: http://scarbsf1.wordpress.com/2011/07/0 ... -analysis/

Summary : any team can run 10% hot blown OR 50% cold blown. He seems to thinks its quite fair. Not convinced...

A reminder for the Ferarri haters from autosport.com today:
"With the HRT team having publicly declared that it was considering a protest against other teams over the issue if nothing was done by the FIA . . ."

They said that weeks ago and it changes nothing. I'm afraid that just because one team has been willing to gain political favour from other teams by going public with something it doesn't mean that others are not involved. Clearly there are some teams who really want this to affect Red Bull......and HRT are at the other end of the grid. There's a reason why Domenicali hopes there will be a 'second championship' this weekend and I'm sure he and Whitmarsh were discussing what Christmas cards they will exchange.

I thought Brabham's ex-spanner man was getting all up in arms about 'hot blowing' (igniting fuel basically)? Why is it still being allowed at all?

Regardless of what control the FIA has over ECUs the fact is that engine designs are different, and worse, the idiot Whiting gave dispensation to teams to alter their engines to do this kind of thing. The genie is out of the bottle and it won't go back in. The only proper way to do this is at the end of the season and with something that will affect everyone equally - exhaust position.

Oh God, if that's true then as Tony Fernandes says it's a total shambles.

50% cold blow = 10% hot blow.

So 100% hot blow is equivalent to 500% cold blow? Says a lot about the Red Bull if that's the case.

Thing is, why not just stop retarded ignition too, then? If everyone is told to stop doing everything related to diffuser blowing then it's all 2009 right? What's wrong with that?

The thing is that Renault have proven that they have been "cold blowing" to cool their exhaust valves since forever and have never been burning fuel in their exhausts (Hot Blowing) - Mercedes are the ones that have been burning fuel in the exhausts (Hot Blowing) and this is what the FIA object to, wasting fuel in this way.

If Renault were prevented from doing this they would have major reliability problems so this is entirely fair as it has always been part of their V8 design and operation - this is also why their V8 has always run so cool and why Newey wanted it for the RB6 and beyond.

The elephant in the room here is that all engine manufacturers have been given dispensation by Whiting to make the changes to the engines they wanted to start blowing off-throttle, they were allowed under the guise of reliability improvements and because of homologation then that is the agreed configuration that the engine will run in. For Whiting to change that will go against agreed homologation changes and will probably be subject to all kinds of appeals from many teams. That's why we have the laughable mess that we do now. Anyone who thought that because the ECU was standardised that this could be controlled is well wide of the mark.

The amusing thing is that everyone, including other teams, have started to realise that Red Bull is not pushing the boundaries of creating hotter exhaust gas as much as others in order to create a bigger effect. They've concentrated more on aerodynamic efficiency, consistent gas flow and making the downforce as consistent and as predictable as possible.

The really, really amusing thing is that other teams will probably realise that all they have done is to handicap themselves and close off a large area of performance gain within a now stable set of regulations that they could have used to catch up.
