My GT3 makes all sorts of strange noises. You just have to get used to it.
For example, after warmup there is a noticeable tapping sound at idle. I'm guessing it's the vacuum pump or maybe one of the scavage pumps. I dunno. The Porsche service manager said it was normal. There frequently will be a brief 'braaap' sound upon startup after the car has been parked overnight. For a long time I thought it was the starter motor. However Nugget's RS does the same thing. Since then I've concluded it's a sound the oiling system makes when it first builds up pressure. And I'm sure you already know about the occasional puffs of smoke upon startup. Yeah, this is a different beast than the Carrera.
Same applies to Turbo and GT2...absolutely normal.
Indications of the age of the GT1-based engines
Not age. Unbridled temperament.
