EDIT: Confirmed. Full story here: http://www.autosport...rt.php/id/91475

Just heard something about no blowing of exhaust gasses in qualy. Not sure what that was about. But either way I think McLaren are in for a better qualifying performance this weekend.

Here's the tweet:
"@TheRealSimonB Qualifying will be interesting this weekend!...No blowing of exhaust gasses. #F1"

He is supposedly the Team Leader/Production engineer for McLaren F1.


I think this could mean a stop to the ******** ignition in qualifying which has made the diffusers much more efficient off throttle. The could be an attempt to mix up qualifying and race performance, as well as keep the engines on an equal platform as it has been speculated the Renault engine is particularly good at this feature. Something to keep an eye on anyway.

Heard what where?

Heard what where?

It was on twitter and the idea seems impossible to police. So don't get your hopes up lol.

explain yourself or just copy/paste so we can work it out ourselves haha 'i heard something on twitter' sounds like a crap book.

[hunnylander]

It may be a joke too. Or expressing something what he [the engineer] can't explain/reveal, because it's confidental information.

The source is a McLaren production engineer. I won't specify the name, because he'll end up as Andy on Twitter.

For questions seeking explanation on the above he gave short averting answers which don't reveal how he meant 'no blowing'. That's all!

Just read some more. Apparently no teams will be allowed to blow exhaust gases. I wonder if the FIA have changed the rules because it means using more fuel, not exactly green...who knows, v interesting though.

That would be a pretty major change for all teams, not exactly in line with costs savings.

[bonjon1979a]

Mclaren engineer announced on twitter @Realsimonb that there will be no blowing off exhaust gases allowed off throttle this weekend. Thoughts?

[bonjon1979a]

What? To switch back to old engine mapping?

Also, it's not about cost saving, it's about environmental credentials. Burning more fuel = bad in the eyes of many.

[Buttoneer]

Explanation?

[ivand911]

Very doubtful. I don't see how this will happen.

[Clatter]

It would require a redesign of the exhaust and quite likely need work on the rear aero as well.

[Owen]

Strange that there's been no official confirmation yet. if true.

[bonjon1979a]

Explanation?

Comes from comments by Team Leader - Production Engineer Mclaren Racing @RealsimonB on twitter.

It seems that he genuinely is a member of Mclaren production team and states that the ruling has come from Charlie Whiting. Details seem sketchy at the moment as I'm getting it from his tweets - he says it's yet to break in the press. Watch this space I guess.

[sharo]

Yes, if they suddenly disallow it, then all diffuser designed around the concept of EBD will lose tremendous amount of efficiency, me thinks.

[Owen]

It would require a redesign of the exhaust and quite likely need work on the rear aero as well.

Which would be a nightmare considering most teams will rock up at Spain with heavily modified floors and exhausts to take advantage of the blown floor concept. On the Renault car for example it's a key part of the car's design.

[Hairpin]

Will it affect Ferrari?

[SCUDmissile]

Will it affect Ferrari?

what do you mean? do they have some sort of new part or something?

[teejay]

It will effect every team with a EBD.

[bonjon1979a]

Yes, if they suddenly disallow it, then all diffuser designed around the concept of EBD will lose tremendous amount of efficiency, me thinks.

It wouldn't be the first time thinks have changed mid-season. But we'll see what crops up in the next couple of days - most stories of significance break now on twitter first so maybe we shouldn't be so quick to discount it.

[Owen]

If this is true, that is quite a drastic change surely (for everyone).

[ivand911]

This will put cars with FEE in good position. There is rumour for MGP doing FEE. But, even without it they didn't use EBD.

Edited by ivand911, 17 May 2011 - 12:31.

[bonjon1979a]

Yeah, remember how skittish the mclaren was when they bolted on the EBD in silverstone with no exhaust run off - whenever they came off throttle the rear end was lively to say the least!

[Group B]

Since no one else has mentioned itm, can I ask WHY?

[bonjon1979a]

Since no one else has mentioned itm, can I ask WHY?

One possible reason is that it isn't very green...carrying 10% extra fuel so they can have better traction...

It does seem strange though to introduce the rule like this. I guess we'll find out in the next few days.

They are always keen on reducing cornering speeds. Anyone like to take a punt on who this may effect the worst? Renault maybe?

[ivand911]

Yes, I think so. It was joke maybe(for sure). To many cappuccinos can do that.

Edited by ivand911, 17 May 2011 - 12:37.

[SCUDmissile]

i mean, like how?

surely it will affect all the teams, but since you just said Ferrari, i was just asking if they have something different to the other teams.

thats all.

[Owen]

mmmm

[sharo]

IF this comes out to be true, then one reason may be that FIA has found some illegality. Like the TMD of Renault which eas banned midseason (although the reasoning then was strange to say the least).

[krapmeister]

If this rumour is true and the reason is because that it isn't very 'green', can I politely point out that it would be the most sh!t reason ever?

You can look at @andydaniell for other bits of the conversation - the exhaust gas mention was gone before I could copy the above.

Could all be nonsense of course! We'll see.

[KirilVarbanov]

How come such major change could be introduced ? Or perhaps, if this whole rumor is true - what's so bad about it ? Looks like the engineers are not allowed to be clever anymore, because some of the teams cannot afford it or it's not env. friendly ? Please, give me a break.
If team A decides that the risk of overheating the engine with aggressive maps is OK, go for it.
But I guess that's enough words for something found on Twitter, where anyone can be someone.

[OwenC93]

Woah sorry guys, I had to go to school and didn't realise it would blow up like this. Yes the tweet was from @RealSimonB , a McLaren employee.

Here's his latest:
"@andydaniell I'm assuming it hasn't reached the press yet!"

And it's for all teams, with the rule imposed by Charlie Whiting.


Now lets get practical with it, I'm not sure how they can police this and force engine maps that don't blow more gasses than they should, I assume he has made a deal with the engine manufacturers to at least stop it off throttle. You'd think it would be announced by now though.

[Ross Stonefeld]

I don't understand why they'd be motivated to ban it, the fuel burn issue is known to a few people on a BB whore read the thread about Renault engine consumption. It's hardly *the* story affecting F1 in the early season.

Though if it is, bizarrely, true it won't be that big a deal. The cars/exhausts/etc will still work fine if they can't accelerate the exhaust off-throttle. They just won't make as much downforce.

But again, why would you legislate engine maps? Or has someone managed to turn it into a form of TC?

[goingthedistance]

This is big news if it has any basis.

Policing it is simple as everything goes via the ECU. I don't believe it would just be as simple as changing the engine mapping.

[bonjon1979a]

Big IF, I'm starting to think!

[SpeedRacer`]

This has to be bollocks. What do you mean "no" exhaust gasses? They can't be stopped!! It's a fundamental concept of many car designs that the exhaust gasses are released further forward. To change the position of the exhaust would require a complete redesign, something which is barely feasible over the course of a season let alone 4 days!!

Perhaps something more realistic would be "no exhaust gasses when the drivers are off throttle" which they could presumably check via the engine maps and telemetry.

But such a regulation would be a disaster, remember this concept was tried in the late eighties and rejected because of inconsistent downforce levels.

[OwenC93]

Yes but there are plenty of arguments as to why an engine creates more gas than normal. I think they could probably stop the ******** ignition though.

This is exactly what was being implied.

If it is because of "Green", I will be a bit miffed to be fair. Like who even knows outside of the few, that it does need 10% extra fuel?
