Am I missing something but wouldn't this only affect downforce under braking? If you aren't on the brakes there might be a tiny bit where the driver is coasting but I would have thought there would always be at least some throttle input from the driver unless he was braking.

For cornering in any racing, you brake then turn in, coast hit your apex then accelerate in the exit. Your braking should be finished before you turn in, Unless we talk about trail braking but let's just leave that one for now!

Or, as goes through my head when pushing (either when karting or on gaming)...
"Brake, brake, brake, turn in, wait, wait, wait, gas , gas , GAS!!!!!"

Or as any Porsche driver would tell you, SLOW in to a curve, accelerate out.

This thread is getting quite funny.


Not as funny as seeing the guy in front of you spin out because he didn't follow simple rules. :hehe:

To get back on topic if there were safety concerns that led to the cancellation of the ban this weekend, without testing, how's that going to change the week after that or two weeks after that?

Judging by your avatar you and I both know the horrid feeling of brake bumps on the turns all to well. :director:

It is understood that the FIA is keen for the off-throttle usage to be stamped out as soon as it can be implemented without causing further complications for the teams.


2012 then, or does that make too much sense?

McLaren's engineering director Tim Goss admits that the MP4-26 will be negatively effected if the FIA restricts how gases are blown through the cars diffuser.

At present teams are adjusting the car's engine mapping in order to force gasses under the car and increase downforce even when the driver is not on the throttle.

This contravenes the FIA regulations which say that the blown diffuser may be used to increase torque but may not be used as an aerodynamic device.

Goss concedes that any change in regulation would impact McLaren's performances and that most other teams will find themselves facing a similar situation.

"I think all of the major teams are up to the same tricks with regards to engine mapping. Certainly we exploit them," Goss said in a Vodafone McLaren Mercedes phone-in.

"If the latest guidelines that the FIA have given us on use of engine to drive exhaust systems came in then it would be a performance setback to us. I know it would almost certainly be a performance setback to our major competitors.

"As to whether it affects us more than our competitors is impossible for me to say. I know what we get out of it and we get quite a substantial benefit, but I imagine it would be just a sizeable a setback to our competitors as well."

With the FIA delaying the implementation of any new rule, Goss says the team are making no special plans regarding the diffuser for this weekend's Spanish Grand Prix.

"We're just working to the latest set of guidelines from the FIA - I think we can react to whatever they tell us reasonably promptly - and for the moment it would appear that the FIA have decided that it's quite a complex matter and that they need more time to consider how they will try and police it. So as a result it looks like at the Spanish Grand Prix it will be business as usual," he explained.

...the FIA regulations... say that the blown diffuser may be used to increase torque but may not be used as an aerodynamic device.


how can a diffuser "increase torque" or do anything apart from "be used as an aerodynamic device"?
#255940
The FIA had an epiphany that the teams are using the engine to influence aerodynamics. They want the engine used only for motive force. The blown diffuser also is an unapproved (and therefore unregulated) aerodynamic implement, and they can't have any aspect of the car escaping their steely grip. Except that engine exhaust always has been an aerodynamic force. The difference is now the teams are managing it to their benefit.

The 'ban' reportedly has been indefinitely lifted. One source says the FIA changed their minds when they were apprised how much disruption implementing it would have caused. Another source says they realised they have no idea how to implement it, no metric for determining who was compliant and who wasn't.

Could it have been an earlier rumbling that this was going to happen that caused Mclaren to ditch the octopus?

So as well as more grip during braking allowing for later braking, with a little extra downforce during braking and coasting you could keep a little extra speed to the apex? And depending on the corner it could give that extra speed out of it and along the straight?

Any extra speed you can carry through a corner is speed you carry all the way down the following straight. If your car builds more power the higher in the RPM range you are then you are also into that power sooner...meaning you gain that much more. All of which means you have to move your braking mark back accordingly once you reach the braking zone at the end of the straight.

WHAT?? Must be a typo "If your car builds more power the higher in the RPM range you are then you are also into that power sooner...meaning you gain that much more".

Sorry dude but I'm gonna say :bs: . Torque is what means the most through the lower rpm range and then hp takes over.
