THe FIA changes the F1 rules againg at the 11th hour not in the middle of the season but in the middle of...............the week end: Red Bull gets 11th-hour boost over blown diffusers - F1 news - AUTOSPORT.com.

I have never seen anything like this. It's war between the F1 teams. Mainly the Renault powered teams (read RB) Vs the Mercedes powered teams (read McLAren). For the other teams they are clueless about what to do.
This a new historic low for the FIA

[AntonayPina]

Renault powered teams are allowed to use it for reliability reasons? So have these teams been running EBD's since the engine freeze of 2006? Mercedes engines have been offered a compromise too but it makes you wonder how much of an advantage anybody has been given really. Why not change the regs at the end of the season and be done with it? We could end up seeing Red Bull even further ahead than they have before over all this!! Oh well.

[AntonayPina]

Reading around it looks like the Mercedes powered teams and Ferrari could end up running their cold blowing at 50% out of protest as they did this during FP2 after this decision had been made. We could have half the grid under investigation and the FIA may well be forced to back down unless they want a complete sham on their hands. I guess we'll know soon enough who has been given the biggest advantage.

What a crock of sh*t! Formula one has just become a laughing stock, and it's all because of this stupid engine freeze!

[zlopikanikanza]

that is all rather a mess isn't it. And this was supposed to be something that cleaned things up

[bapimporb]

Do we need another thread for this after it was already covered in the GP thread? Just asking.

[abOfU9nJ]

Separate topic; so yes absolutely.

I think this is a subject that could go on and on even after the British GP so probably the answer to your question is 'yes'. Plus there are more responses to the subject here.

Have a chill pill and do some reading:

Formula 1

Afterwards it might be clearer what is happening.

Having taken 60 minutes of my life to research the situation, here's what I have found:

1. Following the FIA's decision to ban blowing the EBD when the driver is of the throttle Mercedes has asked for a dispensation claiming that they need to fire at least 4 cylinders even when the driver is off the throttle in order to ease the pressure in the crankcase otherwise they would have had reliability problem, with them supplying 3 teams their request was accepted and the limit for hot blowing (please read above link about cold vs hot blowing the exhaust) the exhausts when off throttle was changed from nil to 10%.

2. Renault engines (read that as Renault the manufacturer, so no RBR BS please) have been using up to 90% open throttle when the driver is not actually using the throttle in order to cool the valves on their engines by blowing cold air through it. They have provided data that shows they did it before the EBD has come into play and they could also prove that without this cold blowing the engines would not last the distance. Given that the engine development is frozen Renault can not change this situation and got a dispensation to have 50% throttle to cold blow their exhaust when off throttle.

The way I see all those who asked for a dispensation did receive one from the FIA, who are more or less trapped between this stupid mid season rule changes that most probably was requested also by other teams than just HRT, and the need to allow for dispensation if they don't want to lose several teams on the grid. Serves them well for changing the rules on the go.

The one possible way out of this is to postpone the rule change to next season when the exhaust will have exit above the engine cover anyway.

I wonder what Ferrari thinks about all of this and what card they will play if any.

very succinct Ioan, and from what i've read that seems to be the case, although i did see something that renault only ran at 45% but that can't be right if they now have dispensation for more than they ran before

As far as I understood Team Renault ran it up to 90% and RBR up to 45%, maybe we will get exact data from the team or from the FIA.

[adultcomicssitedessaa]

I laughed so hard when I found out that the Renault engines were given a dispensation to run at 50% off-throttle exhaust blow and RBR only use 45%.

Awesome!

OK, so renault will be slower yet RBR actually will improve their blown diffuser by the imposition of rules to outlaw it? i can see why McLaren and Ferrari are a wee bit peeved about the whole thing

I guess RedBull will not use 50% given that they designed the car for 45%.

I am not yet sure where Ferrari stand right now as they didn't make any press release.

For everyone's sake I hope the FIA ditch the rule changes ad everyone continues from where they were 1 month ago.

Quite.

[GroosteFoessy]

Thats why sitting in the stands, I thought it sounded as if the Red Bull was still using it. I was confused as I didn't know of this development.

It is being rumored that everyone used it in FP2.

[GroosteFoessy]

By second practice I was so wrapped up from the rain, I couldn't hear anything. (Well almost)

F1/FiA never seems to learn about changing the rules halfway through a season. Ridiculous - only for safety reasons should this happen. Talk about shooting oneself in the foot. Honestly, I can't be doing with it all....a complete joke.

That's it, as it now it's complete mess.
I like Jean Todt but this is too much.. take it easy.. changing the rules halfway through a season is not ok.. What next?
