If you have a dB meter or app for your phone I would appreciate knowing the sound pressure level at 3k rpm with no load.
The stock M3W produces 93db @ 3k rpm according to the placards affixed to the machine. I measured a stock one yesterday at 91db @ 3k under no load. My AR Stage 1 measure 110db @3k no load so the G56 will be N interesting number.
Stephen, I just went for a 50-mile drive and my wife took readings using the "Decibel X" app. Depending on location (narrow canyon, a bit wider canyon, other traffic around and little traffic around), at 3K rpm under NO load cruising, the readings were as low as 86dB and as high as 90dB. She was holding the phone and keeping it centered in the car at a chest level.
Obviously different devices and apps would yield different results, but considering this is a $15.99 app and claims to be calibrated blah blah blah ... I think its probably reasonable i.e. not total junk.
So - somewhere between 86dB and 90dB is what I found
