I still have a loud cricket like chirp when i rev above 5k, but it's not as bad as it was with the top up. I feel a lot better after driving top down lol. Moral of story, the spyder top is terrible, and don't use it unless you have no other option lol

I'd also like the owner to listen to my video that I posted a link to above and try to duplicate what I did with the RPM's. Slow rev from 800 to 2000, back to 800 and then slowly back to 2000. If there truly are cars that do not chirp like mine, I am going to push PCNA to at least make mine better.

It is quiet at cruising revs, 2-3k rpms so there's that. Above 4k rpms, it is raspy and it not at all a tone that I expected. What a conundrum!

I love the power delivery of the 4 liter compared to the turbo six in my 911 as well as the shorter throw shifter and the familiar mid engine platform but I am very surprised by the sound quality of the engine. The memory of my C4S is still fresh in memory and that engine while muted didn’t sound so uneven and gruff. The 992s don’t sound that different from my 991.2. I guess the big displacement 4 liter engine as well as how Porsche has engineered the sound for various reasons seems to have impacted sound quality in a very unexpected manner for me personally. The driving experience is excellent though. But I am beginning to build a 992 S on the configurator which is not a good sign for my wallet.

They do hear the sound but are following Porsche's process. Given that it took two years to get my car, it may be a stretch to find another example car. So continuing to wait here.
