Adjustments to BOP in GTE-Pro has been announced ahead of the Le Mans race.
Ford have to carry 10 kg more ballast plus there are some boost levels are lowered.
Ferrari have to carry 25kg more, but will be able to carry 4 liters more of fuel.
Aston Martin will get a 0,4mm bigger restrictor and therefore get a bit more power.
Corvette was allowed to have 0,3mm bigger restrictor, but they only have a 0,2mm bigger version, so they have to stick with that, unless they find another solution shortly before the race. Additionally they are allowed to carry 7 liters more.
Porsche are allowed to carry 8 liters more fuel than before this BOP change.
Lets see what affect it has for the race, or if Ford and Ferrari can go to another level and stay unaffected by the change. There was a gap of 3,5 seconds down to first non-Ford/Ferrari car, so thats a lot of time to catch up. If BOP was done with pure weight, it would be another 180kg for those 2 cars. But instead ACO chose to add a bit of weight, and give the others (expect Porsche) a bit more power.
