My 997.1 seems to be blowing rasberrys on start up, as soon as I move off and increase throttle it's gone.
Initially thought it might be a baffle on its way out, but only makes this sound on startup. Figure if i5 was a baffle going then there would be noise throughout the Rev range?
Do the 997s have a pressure valve of some description to cater for additional pressure on cold start?
