Despite the change of regulations in 2011, since the first races of the season, were able to see that parity between engines diesel and gasoline, again, did not exist. The diesel were again much higher. That is why, after 12 hours of Sebring, the 1,000 kilometers of Le Castellet (Paul Ricard HTTT) and the 1000 km of Spa-Francorchamps, the ACO has made modifications to the regulation to improve the performance of the prototypes of gasoline (Rebellion Toyota Racing engines)(, Judd in the Team Pescarolo and OAK Racing or Aston Martin AMR-One). The measures will start to apply from the great event in the calendar of the ACO and resistance, the 24 hours of Le Mans in 2011.
In the 24 hours of Le Mans in 2011, so that the gasoline engines are less than 102% of the time of the best diesel engine, this type of propeller will have with a flange of admission increased by 0.3 mm. larger and may also will be reduced in 10 kg maximum weight. In the event that an LMP1 can not remove these 10 kilograms, may benefit from a 0.5 mm flange largest.
Finally, the diameter of the hose of gasoline cars will have 10 mm, whereas in the diesel will be 0.3 mm. smaller. Be seen, already in training, whether these measures are sufficient so they equate with the petrol diesel engines. I fear that these changes will not be sufficient and the Peugeot and Audi will continue to be much higher.
