Z4 M w/ ESS Supercharger. Rattle during engine shut off
I recently purchased a 2006 Z4 M coupe. It got a ESS Supercharger stage 1 kit. Everything else is pretty much stock. Motor got 90k mile. The supercharger was installed 40k mile's ago. The car drives great, still pulls pretty hard. The only thing that's bothering me is a rattle around the supercharger during engine shut off. With the clutch in or out its still the same. It's a very noticeable sound, but I'm not sure if It's normal. I made a short clip, maybe someone can chime in. Just listen to the rattle as the motor is shutting off.
Thanks, Dan |

sounds pretty normal to me, these blowers add loads of mechanical noises.....
As long as theirs no play in the pulley i wouldn't be worried, of course make sure the oil level in the blower is good.
