The alternative is a common flywheel or what is more commonly called a light weight flywheel (LWFW) which is a standard aluminum flywheel. Because it does not contain the flexible damping material and the other mass, it weighs substantially less and thus, the engine will rev a bit quicker. The downside is that there is concern that the LWFW can result in engine failure due to undamped crankshaft vibrations.
Do a search on LWFW and you'll find the threads where this has been discussed with quite a bit of passion previously.  |
Ive never heard of boxster motors popping from a light weight flywheel, looks like I have some reading to do. How well documented is this? Is it a real concern?
