The combination of a 3% gain in restrictor area (-> 3% gain in power) and reduction of weight of the car gets the gasoline cars pretty close to last year's configuration that Dyson ran, from a power-to-weight ratio perspective. They ran the ACO mandated restrictors but at 860 kg - this would be equivalent to running at near 875 kg. (For reference, Petit Le Mans P1 cars will run at 880 kg, so we'll see an equivalent test of the theory next weekend.)
I do think, however, that the Audis will be in the 915 kg range next year, negating some of the advantage set out in these new rules.
I also don't disagree with the ACO's P2 weight addition, from a Le Mans perspective. I think IMSA should implement the rule in 2009, though.
