    Grace period for blown exhaust limit

    The FIA has given the teams a grace period before enforcing a ban on the way exhaust gases are blown through diffusers.

    Formula One's governing body has concluded that the engine had become an aerodynamic aid controlled by the driver, which is not permitted in the regulations. In order to prevent this, the FIA will ban the blowing of exhaust gases beyond 10 per cent of full throttle, and had originally planned to impose the ban ahead of the Spanish Grand Prix this weekend.

    According to Auto Motor und Sport, however, the ban will now be imposed at a later date agreed with the teams to ensure that some are not unfairly penalised. Mercedes team principal Ross Brawn says the ban will have a significant effect.

    "These sort of staccato exhausts that you hear, I don't think you will be hearing anymore," Brawn told Reuters.

    Red Bull is widely believed to have mastered the blowing of exhaust gases through its diffuser, and the ban could be a result of a complaint from rival teams unhappy with the way it controls its engine. McLaren's Phil Prew had previously said that he believed Red Bull's qualifying pace to be down to the way it uses its engine to maximise the potential of the exhaust gases.

    "The use of elaborate engine modes may be [a reason it is quicker in qualifying], with the generation of downforce being quite highly influenced with the exhaust flows," Prew said.

    When asked if the ban was likely to be the result of a complaint, Red Bull team principal Christian Horner said:"It is inevitable and the unfortunate consequence of success."

    FIA ban would affect McLaren

    McLaren's engineering director Tim Goss says that the performance of its car would suffer if the FIA introduces a limit on how exhaust gases are blown through diffusers.

    The planned ban focuses on engine modes maintaining the flow of gases through the exhaust even when the throttle is not being used, in order to enhance downforce from the diffuser. The ban was initially going to be introduced for this weekend's race in Spain, but it has since been postponed indefinitely to ensure that no one team is penalised unfairly. Goss said he was unable to work out how much it would disadvantage McLaren compared to other teams, but that it would affect it.

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

    "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."

    Red Bull team principal Christian Horner yesterday believed the ban would have been due to a rival team complaining, but when asked how the proposed ban came about, Goss said he was unaware that it was even being discussed.

    "I don't know whether they've taken it on themselves to clampdown on this or whether they've been prompted to. I think since the middle of last season then it's come quite apparent to journalists and then hence the public that teams have been changing their engine map to get more out of exhaust momentum and the effects of that on the rear end of the car - or in Renault's case the front end of the car. So I think it's been around for a while, but there hasn't been much debate about clamping down on it if any."
  3. F1 is about putting as many hurdles possible in front of innovation.
  4. Yep.
  5. the rules are just a really crappy made dam trying to hold back a flood. Rather than actually doinitrite they just shove shitty patches everywhere.
  6. I think they shouldn't change the rules during the season.

    Finding loopholes should be rewarded not banned.
  7. except it was williams who made the complaint, dumbass
  8. But thats why its being banned. Because the FIA has determined that its not just a loop-hole. Its a dial the driver turns that AUTOMATICALLY aids downforce through ECU fuel mapping.

    Now I dont agree 100% but at least see what they're saying. I'm just happy they dont pull stupid stuff like they used to DURING RACES!
  9. aaagh Whitmarsh complains all the time about Red Bull.
  10. i keep dreaming of air restrictor plates and no aero/engine rules.

    can you imagine the technological advances and ingenuity that would evolve?
  11. Or simply the possibility of teams choosing to run engines similar to what their manufacturer's road car division uses. Mercedes using larger capacity V8s that bellow like AMG models, Ferrari using V12.
  12. that wouldn't happen, because they know what is efficient with a restrictor. What you could see was people using things like turbines, super tiny turbo engines, maybe a V12 in there, maybe some turbo rotaries, etc.
  13. I dont get why people think that all these unrestricted rules would be so awesome. I dont love Formula1 because the cars are so up and away futuristically advanced. Its for the competitiveness of the teams to work with and around the rules. Its the rules keeping the from teams near the back teams so there is a competitiveness on the track.

    Rules are a reality of high end motorsport. Get over it. The more simplicity in the rules the better the racing. WSBK has it right at the current moment where private teams run along with the manufacturers. But is in an entirely different realm compared to open wheel regulations.
