Lightweight Flywheel??
When looking at and test driving a car, is there any way to know for certain that a lightweight flywheel has been installed? Or, do you really need to open it up? Is this something a PPI will verify?
Thanks Al

I think that for the "untuned" ear it will be kind of difficult to tell by sound. The motor should rev up faster than the heavier dual mass equipped cars. And, the downside to the LWF is that it transmits some transmission noise. In my car, there is a slite "rattle" at idle sometimes that I believe is the gear noise from the transmission that is wicking through the flywheel and becomes audible.

I've never driven anything but the lightweight flywheel on the 911, but based on other Porsches I've driven you can take it down the road a bit and as you upshift push in the clutch and instead of shifting, watch the tach..if it drops much and rebounds (or even cuts off) you might have a lightweight flywheel.

There may be a way of telling via the inspection port - anybody know for sure?
