Ferrari’s Balance of Performance for the Le Mans 24 Hours was adjusted on Wednesday, resulting in a power reduction.

As part of a series of revisions made ahead of the opening practise session at the Circuit de la Sarthe, the turbo boost pressure curve on the 488 GTE Evo of the Italian manufacturer has been lowered.

Its boost ratio has been decreased by 0.07 over the rev range, bringing its power curve closer to that of the 2021 Le Mans, though with somewhat more power at low rpm and less power on full throttle.

The Ferrari’s fuel capacity has been reduced by three litres to 87 litres, while the minimum rear wing angles on both the 488 and the Porsche 911 RSR-19 have been altered.

However, the Porsche’s power curve and minimum weight have remained unchanged, while the current BoP for the Corvette C8.R has remained unchanged. The Ferrari’s minimal weight stays unaffected as well.

In the GTE Am class, Ferrari has also reduced power, but the boost ratio has been adjusted slightly less than in the Pro category. Similarly, the gasoline tank has been reduced by three litres to 84 litres.

In GTE Am, the identical rear wing angle modifications apply to both the Ferrari and Porsche. However, Aston Martin Vantage GTE, which now only competes in Am, has received no changes, like the Corvette.

On the official test day on Sunday, all three GTE Pro manufacturers were fairly matched, with the top Corvette, Ferrari, and Porsche vehicles separated by less than three tenths of a second.
