24H of Le Mans 2023 - GTE Am BoP unveiled
With two wins and a second place finish, it would be an understatement to say that the Corvette C8.R has had a successful start to the season. Does this mean that the BoP needs to be perfected? Not necessarily, given the performance of the #83 Richard Mille AF Corse Ferrari 488 GTE, which was forced to retire at Sebring but finished second at Portimao before winning at Spa.
But we were still eager to find out about the BoP in force for the Centenary of the 24 Hours of Le Mans. Especially as, as a reminder, the success handicap - which requires the best-placed competitors in the last two races and in the championship to carry extra ballast - is not in force in La Sarthe.
We'll leave you to look at the figures in the table below, but since Spa, the Porsche has gained 31kg, the Aston Martin 17kg, the Corvette 24kg and the Ferrari two kg.
The Italian, however, has seen its boost pressure (Pboost ratio max vs RPM) fall (-0.03), unlike the Vantage AMR (+0.05). The diameter of the air restrictor of the C8.R remained unchanged, while that of the 911 RSR-19 increased by 0.1 mm.
Compared to the BoP of the GTE Pro at last year's Le Mans 24 Hours, the Ferrari has lost 5kg, while the Porsche has gained 15kg and the Corvette 20kg, while the diameter of its air restrictors has been reduced by 0.6mm. If the Aston Martin was only in GTE Am, its weight remains unchanged but its boost pressure (Pboost ratio max vs RPM) has increased by 0.07. But once again, it's difficult to compare since the British car was not in GTE Pro and the legislator seems to have based his decision on the BoP in force in GTE Pro - and not in GTE Am - here a year ago.
Finally, if we don't mention the amount of fuel on board, it's quite simply because the legislator has ensured that all cars are able to complete the same number of laps per stint.
