FIA makes major changes to blown diffuser regulations – Formula 1 news
According to some recent reports, it has been revealed that the International Automobile Federation (FIA) has made some major changes to the regulations regarding the exhaust blown diffuser.
It is believed that the design and execution of this device is one of the major areas in the 2011 season in terms of car development. Most of the teams are trying to focus on this system in order to obtain as much advantage as they can as compared to the
rest of the teams. It seems now that the results of the upcoming race in Spain are going to be quite unpredictable.
“It will affect all the teams. These staccato exhausts you hear, I don't think you are going to hear them anymore. The teams have all been developing their engine management systems to get the maximum advantage from the exhausts, and the FIA want to push
us in a different direction now so there will be changes there,” said Mercedes GP team principal Ross Brawn.
The teams are mainly trying to use this device in order to increase the downforce of their respective cars if required especially when the throttle is not in use.
According to the rule change by the FIA, the teams can now clamp down on what they have been up to regarding their blown diffusers.
Other than that, rumours suggest that the FIA has informed the teams formally that they will no longer be allowed to continue with gases flowing through their respective car engines when the drivers are not on the throttle.
“It is inevitable and the unfortunate consequence of success,” said Red Bull Racing Team boss Christian Horner.
This means that the throttle input cannot be longer than 10 percent of its maximum from now on as it is believed that some of the teams were gaining aerodynamic benefit by keeping the throttle flow at 100 percent under braking.
As a result, the FIA added that the throttle will now only be allowed for increasing torque and not for any sort of aerodynamic advantage.
