Grant, most of the testing of a new airplane is done indoors often before it is built. The test flight only validates the data.
That said, I understand your passion for racing and why it is important for you to know Porsche has a racing program. But tell me; if Porsche shut down their racing program tomorrow would you still buy the 991.2GT3?
If you have followed the drama that is currently unfolding with the GT3 engines (I know you sold yours well before the most recent issue was fully understood), I believe that design flaw causing early failures is directly a result of the 991.1 GT3 being the first GT3 ever not to be powered by a race-tested engine.
Thankfully, the 991.2 GT3 engine does benefit from lessons learned from racing the GT3 R race car. But even so, the racing experience may have been too short to fully address all of the issues.
So, yes it would concern me if they stopped racing (not so much related to the 991.2 GT3, but more for any subsequent engine with no racing pedigree).
Here is the thread, been getting more and more interesting lately:

And there might even be some relevance to this thread (shocking) I think some have said the GT2 RS may be a turbocharged version of the 4.0L RS motor (also to used in the new GT3, with updates). And if the GT2 RS is a homologation for the next turbo race car, this is good news for further development of this motor in competition.
