L'Argus magazine states that all RS 280s made after summer-autumn, benefit from the ceramic turbo that Trophy has, along with a different engine map. They even say this information was given to them by the chief-engineer of RenaultSport.
The first version of Megane RS280 had a declared power output of 276 HP, the new one has a declared output of 279 HP. And while 3 HP obviously won't make or break the whole deal, the addition of the new ceramic turbo more certainly will. Ceramic turbos are well known to give much better engine responsiveness, due to extremely low friction, some say that such engines are behaving almost like non-turbo ones, with no turbo lag and power delivered extremely linear, till the red zone.
The reason is the much better and powerful air flux into the admission, due to the decrease of turbo friction that, in turn, translates into an increase of rotational speed. As stated by Renault, the new ceramic turbo can almost reach 200.000 rpm, while a regular turbo almost never reaches 150k (for example, the mighty BMW 3l engine turbo can go anywhere between 70 and 130k rpm), so the increase to 200k (or almost) is quite substantial.
