I'm not sure that I follow. According to the interview I read, when asked if the new GT3 engine would be used in motorsport, AP stated that it would, but that they (Porsche) were not yet sure in what format.(Turbo,NA).

 

FLATSIXES: Will the new engine in the 991 GT3 make it to Porsche motorsports? If so, can you say when and where?

Andreas Preuninger: Sure, it was developed with this exact focus by the same engineers that did all of the flat-6 race and street engines in the past. The reason for not having the engine in the new 991 Cup is mainly timing, because Cup cars are already in production and the streetcar development is still ongoing, now in its last phase.

Secondly, it is a totally different engine and as such, the education of the race teams on how to deal with the new technology is complex and has to be done right and in time.

Future use of this engine in other 911 race cars is planned but in which form the engine will be used depends strongly on future regulations (for example turbo or non turbo).
