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.
