Exhaust gases and diffusers...

Now, if it was say Lotus who had come up with this idea and were crushing the competition, then there would be no problem.

All part of the show, just like 2009...

 

I'm thinking that the FIA reneged on their ruling because the KERS system is charged by the engine when off-throttle. Trying to regulate the off-throttle mapping while maintaining enough juice to power the KERS would probably be too hairy.

 

So would MB benefit most from the ban on off-throttle exhaust blowing on the diffuser?

 

I can't really tell yet. The cars with the EBD have more benefit when off-thottle as their close exhaust positioning and engine mapping can have a greater and quicker affect on performance while teams like Renault and MB don't really have much benefit from that type of mapping as their exhausts do not rely on the immediate energy of the exhaust itself so much. But rather MB and Renault rely on the presence of the exhaust to create a low pressure area rather than it actually blowing on something so much. We'll have to see to be sure really, but I know MB/Renault are not affected by it as much as others which makes it somewhat odd that Brawn was one of the main proponents in not having it in effect so immediately due to some sort of danger. I suspect the danger was due to teams non-linear throttle mapping they will swap to once it's gone which would be very dangerous and I don't think that should be allowed either.

RB was the one who started this mapping business and they have a special setting for qualifying which they can only run for a couple laps as it makes things run incredibly hot, but they are getting about a half a second advantage from it. Mclaren caught onto it this season and Ferrari was starting to catch on. Whiting has essentially had enough of that garbage though.

 

This might be almost too simple, but what will stop the driver from simply pulling in the clutch lever and holding some throttle while going in to a corner???

All teams will be affected to some extent, however the more aggressive that teams have been with the exhaust position relative to the floor, then the greater they will be affected. From the start of the season Red Bull, Ferrari and McLaren have blown the exhaust at the outer 5cm of diffuser. this area is allowed to to be open and bow the exhaust gas under the diffuser for greater downforce. these designs will be most greatly affected by the clarification. Renaults Front Exit exhaust is also likely to be a victim of the change. Many teams have been developing Red Bull Style outer-5cm EBDs, such as: Williams, Lotus, Virgin, Sauber, While Mercedes are rumoured to be adopting a front exit exhaust. These may to need be shelved after Canada, in order to employ a less aggressive EBD.

 

The wheels will lock up under that kind of braking pressure without being in gear.

 

Also the fact that there is no "clutch lever" in an F1 car.

One big question is managing the delicate balance of overrun/rear bias. The overrun sensitivity dramatically determines under/oversteer tendencies and is usually dynamically adjusted in combination with differential lockup adjustments. Trying to recalculate all of these things in one week is practically impossible. This may be the thorn with which the teams popped the FIA balloon.

 

Incorrect.

Two (of the four) paddles behind the steering wheel actuate the clutch. [The other two are up & downshift.]

Beat me to the punch
In any case declutching couldn't be done with sufficient finesse to work.

 

Not to get super technically picky, but aren't there only two paddles hinged in the middle...? One for shifting, one for the clutch

 

The layout varies from maker to maker. Sometimes from driver to driver on the same team.

 

what? why?

 

More resistance when in gear, ie more torque is needed to stop the wheel??

But all you'd have to do is switch to more front brake bias. Plus if you have the EBD you are getting more downforce on the rear which evens out the tyre loadings under braking, negating the need for more front/less rear bias.

IMHO of course

 

exactly....well, maybe rear bias...but regardless.....that's all you'd need I'd have thought.

 

I think you could set the cars to a very high idle, with perhaps a button or switch to turn the engine down when rolling into the pits, etc.

 

Whiting just had a meeting with all the teams after practice 2 regarding the EBDs. I would have loved to be a fly on the wall in that room.

There is some confusing rhetoric at the end of the above review. The specifically mention MB as a team particularly gaining from the concept, but they are not clear if MB is gaining from the BAN or gaining from the current exhaust benefit? No biggie.

 

No sir. As Dave noted, it varies a little but I'm 99% sure there's 4;

- Two (I believe both need pulling) for the clutch
- One for upshifting
- One for down.

Can't find it now, but there's a few Youtube videos detailing what's what on the wheels.

Cheers,
Ian

 

Sorry for being so OT

Charlie is really stoking the fires today. He essentially told the top teams in the meeting that the small teams can protest what they are doing. Seems to me like he is planting ideas in smaller teams heads (if they weren't already there) to get THEM to make the call by protesting it rather than the FIA to come out and be the bad guy. Clever.

Odd. It's as if Charlie needs cover to do what he wants.

 

That was my first idea too - just compress the normal pedal mapping to higher percentages and add the former off-throttle mode below. However, this solution would be SO easy that everyone would have implemented it by now and there wouldn't be any discussion...
