Now if you are saying that there is a possibility that the current design of the 9A1 would have benefited from having an IMS, I can't argue because I can honestly say I have absolutely zero experience with that engine, but based on what Subaru (just an example) has done with their engines, I don't see why Porsche wouldn't have the ability to make it work too.

Some component must reduce camshaft speeds by 50%, no matter what the engine may be.. In my experience you want that 50% reduction to occur as early in the mechanical "chain" as possible to reduce surface speeds of chains and etc.

When I first saw the proposed "new engine" I knew it was going to be hell on timing chains.. From the reports that I hear within some dealer networks I am part of failed timing chains are occurring.
