Hi, proud owner of a 2008 2.7 Cayman with 193,000 miles !! She runs so strong. Anyway, have a whining/whirring pitched sound from engine that follows RPM with or without speed/clutch-engagement Lower pulley changed, power steering topped off. No dice

Hi, proud owner of a 2008 2.7 Cayman with 193,000 miles !! She runs so strong.  Anyway, have a whining/whirring pitched sound from engine that follows RPM with or without speed/clutch-engagement   Lower pulley changed, power steering topped off.   No dice.  Porsche techs seem puzzled ( some saying normal - NO WAY).  Thinking alternator or alternator pulley (can the pulley be changed without cost of new alternator)

Any/all advice most appreciated.   Love this car and will drive it to end-of-earth.

Tweaked suspension only (GT3 bits, slightly lowered - go-cart handling w/MIch 4S's) :-)

Thank you so much

Nick
