Short whistling sound when accelerating...

[RW1]

started at about 200 miles. Only squeaks from stationary using mild to hard acceleration.

That's not unusual for the newest version of the supercharger clutch. And replacements are generally the same if you have it replaced under warranty.

Gentle acceleration doesn't seem to make it do it.

It will soon unfortunately.

It won't squeak/chirp above 3,000 - 3,500 rpm as the Supercharger clutch won't engage if you demand torque through the accelerator. By that rpm and above, its turbo only.

The squeak is most noticable when the Supercharger is engaged at around 2,500 rpm engine speed and the Supercharger has to wind up from 0 rpm to 5 times the engine speed, ie 12,500 rpm-ish in an instance.

Ahhh. Ok. I'm loving it so far despite the quirky noise. Love the sound of (what I think) is the supercharger kicking in on acceleration from stationary. Sounds sweet! Loads of steep hills around here and makes a lovely growl, whistle (and little squeak sometimes) driving around. Hehe
