Exhaust blown diffusers and FIA restrictions/ban

[i70q7m7ghw]

Only reason the weight penalty isn't a big issue at the moment is the mandatory weight distribution, but from my understanding, that was only ever temporary.

EDIT: Yes, 2011 only.

Sure but does it say that the minimum weight of an F1 car will change for next year?

The minimum weight won't change no, but the weight distribution will be opened up again. I don't think the total weight of the car was ever an issue for KERS, I think it's always been a distribution issue, without it teams had more ballast to move around to improve the balance. This year that's not possible because of a fixed weight distribution.

So there would be no weight penalty at all, just a weight distribution problem which as you say probably cause more damage to a car then extra weight.

A certain amount of this is going to be handled by driving style changes .. trying to spend more time on throttle in corner entry, such as braking earlier and rolling thru corner entry on some throttle to rebuild down force. We'll see if Webber starts getting the upper hand on Vettel with these changes, as he had in early 2010.

The cars have numerous maps to select from based on race conditions, car issues, is that all gone? If not how can any restriction operate?

Finally, with immediate effect, it will no longer be possible to reprogram the ECU configuration between Qualifying and the Race in the expectation that this will discourage extreme ECU setups for Qualifying

As far as I can tell, this implies that there are a set number of maps available on the ECU and that the teams were using perhaps double those maps over quali and the race. It seems that they will now have just one set of maps to use over the whole weekend. Considering the advantage that the retarded map gives surely you'd choose it to stay and sacrifice another or combine two in order to keep it.

I had actually wondered if teams might start introducing a third pedal used to retard the ignition... The rule bans coming off the throttle and still having the engine running. If the driver is still on the throttle, but also on the retard-ignition pedal, they're not breaking the rule.

That's still driver influenced aerodynamics, though, beelsebob. Easy ban I would say.

"The driver isn't controlling aero, he's controling the engine, honest gov" – Same reason they need an explicit rule change now to get the ban into force.

[hardingfv32]

I would say retarding the ignition is considered a engine map change which is now not driver controlled anymore.

I was actually just reading through the rules on this again... As I read it, hot blowing is banned already:

5.5.3 The minimum and maximum throttle pedal travel positions must correspond to the engine throttle minimal (nominal idle) and maximum open positions.

[beelsebob]

I'm confused... I just reread the rules here...

5.5.3 The minimum and maximum throttle pedal travel positions must correspond to the engine throttle minimal (nominal idle) and maximum open positions.

Doesn't this rule already ban hot blowing?

[hardingfv32]

It is being implied that the engine map cannot be changed until the first pit stop and maybe not by the driver.

KERS... "but the weight distribution will be opened up again."

Could this be because next year the KERS is much more powerful and would then become a must have item?
