What evidence is there? What would be the perceived benefit?

I'd agree that this is a very questionable idea.

Do you have any understanding of what was happening during 'hot' blowing? I am not sure that in all the discussions it was made clear exactly what was happening with the throttle position, timing, fuel delivery and pedal position.

Before you guys babble out some simple explanation, think a little about the all the driving conditions this type of system has to account for. It would be my opinion that the new rule correlating the pedal directly to the throttle position rules out 'hot' blowing.

There is nothing illegal or problematic with a 5K idle setting. I do not know if that would make for an unusual pit sound. Could Some teams be using a high idle setting to cool the valves as they did in the past? Decelerating with a high idle setting could sound odd.

I think hot blowing may still be achieved at any throttle position but it would ONLY work at full strength in that Narrow window when the throttle is wide open by the driver's foot - during acceleration out of the corner - Or some trickery with the cluch or neutral. Last year, as you know the throttle was being opened by the computer in times when the driver would be braking, increasing the window in which the hot blowing can work at full strength.

Personally, I'm sick of the 'intent' garbage, rules should be back and white. If someone finds a loophole, then close it for the next season. The concept of 'intent' being interpreted by one person is way to big brotheresk for me. It basically lets one team wine about others because they can't compete on their own merit.

Can Whiting go back and change his mind about the legality of the mp4-27 positioning, if the car happens to dominate the first few races?

It will be interesting to see if there is any major change in tomorrow's practice. I guess if the cars sound different, we'll know who was using it and who wasn't.

Better that Charlie closes the loophole now than after the third or fourth race, like he usually does. Perhaps the difference in this case is that he has a tool - the ECU - that can effectively eliminate the loophole.

I completely disagree, whats the point of having rules if they can be changed on a whim. In my opinion they only time they should be changed after development has started is because driver or spectator safety is in question. Even then I think it should be up to the teams to vote and decide. Teams spend millions on development and arbitrary rule changes throw it out the window. I would say it's almost anti-competition.

This decision appears to be an FIA decision, not Whitings. It also appears that it may have been Williams who brought it to the attention of FIA.

I was reading this on a German site this morning.

In fairness the FIA were explicit about "aggressive" maps. How you define aggressive is the bone of contention for me.
Can you add a number? Measure it?

Ferrari are within bounds to "highlight" this if there is a flagrant lack of respect for the spirit of the law. That is their right.
More could have been done.

if you read the AUTOSPORT version it says so far no team are know to have exploited this loop hole yet but the FIA were simply making sure no one did in the future

I just hope this had nothing to do with Macca's planned upgrade next week
