You're spot on Anthony, the 9A1 in the 2009+ 987.2 has been motorsport tested and has proved to be bulletproof. In both the Intercontinental Trophy Cup Racing Series and the Interseries there have been no blown motors except from over-revs on misdownshifts and I've only heard of that happening on one car where the guy was redlined in 3rd, down shifted to 2nd and floored it lol.

Fully correct Carrera
New 991 GT3 will be with DFI and will be 9A1 engine..
Your and our concerns are that the 9A1 has no motorsport background,in fact its not a real dry sump engine..and no race car in the world is winning races without dry sump (PS: 9A1 engine does not allow slicks)
That is the issue..the 9A1 engine needs to be revised completely for that..
Lets see..

Doesn't even the new Boxster S engine feature a dry-sump system, or something along those lines? I may be wrong, but I'm quite sure that it allows Semi-slicks (e.g. Pilot Sport Cup), just like the previous GT3. That said, I see absolutely no reason for the 991 GT3 engine to not feature a dry-sump system.

Oil starvation.
Running slicks when racing - or even during a DE - allows generation of higher g levels while cornering. Sustained periods of high g cornering may lead to oil starvation with a conventional wet sump oiling system. That's why race cars and aggressive street cars - 997 GT3 (in fact, any Mezger engine, so the your 993, for example, also counts), Corvette ZO6, etc. - have dry sump oiling.

My question was why would someone assume because it had pilots on it that it was dry sump.
It makes no sense.
My RS America has slicks. Should I assume it's dry sump?

Perhaps any car that does run slicks should have dry sump oiling.
Unless I'm severely mistaken and walking into a "gotcha!" moment, your RS America does have dry sump..
