Jake,

The IMSG is a chip detector, an electronic instrument that attracts ferromagnetic particles. Your IMSR bearing is ceramic right? If your bearing fails, how does the IMSG detect it since ceramic is non-ferromagnetic?

Expert please enlighten me. Love to stuff my brain with interesting information.

The IMSR is less load rated than the oem one. It is also less speed rated then the oem one. All the reading I have done from the forum here and advice from previous owners are that These cars need to be driven like grandma on steroids! One seller even told me that at each gear it should be taken upto 6k rpm before shifting. That maybe overkill but i can say that it makes my stupid grin wider. And i dont mean redlining it.

So, am i looking at moving to a conservative driving style with the IMSR compared to oem given load and speed ratings? And also have the same question as Jaxonalden below. These ferrous bit that are present prior to the failure are from the balls or the casing? What actually goes first and lights the fuse? And how do both differ in that process?

I wanted to address this separately.
The races and cages of the ceramic IMSR are still ferromagnetic and will trigger an IMS Alert. We have carried out this specific testing all through 2011.

BUT in applications where the IMSR is employed the IMSG is more useful in alerting the driver of the other ferromagnetic wear metals within the engine.

Won't the heavy metal cage be slower accelerating/decelerating than the ball bearing itself? Causing the ball to bang the against the cage, accelerating wear on the cage? Eventually banging chips in the ball itself as the ceramic ball sharpens the the edges of the metal cage?

I think that is why bearing companies use nylon or Teflon cages with ceramic balls as they are lighter and can keep speed with the ball itself.
