The variocam doesn't actuate until you hit 4200 rpm so it's important to move past this range to exercise the motor fully.

However, with that said, I do not wind up the motor past 4200 rpm until its fully warmed up.

I am a firm believer that a Boxster motor taken to redline regularly will keep the motor operating smoothly, even if it shortens its life. It's a good trade off.

Noise may be the trailing arm (longest lower control arm). They're often the culprit of a clunk.

New motor, transmission, suspension, and on and on and on it goes...
