981 with PDK still need DMFW

[sb01box]

Curious;
987 & 981 with PDK still require dual mass flywheel to decouple the engine and the transmission?
Or do the new design have forged crank and or beefed up engine main so DMFW is no longer needed?

The 981 uses a dual mass flywheel for the manual transmission, not for PDK.

my understanding is that PDK is computerized manual transmission. so it should have similar engine/transmission coupling. If PDK system does not need DMFW, and the crank is not forged, but built with the same technology as 986 or 987 (pre PDK), then what's the rationale for not needing DMFW

The clutch is completely different on the PDK, and there's 2 of them , so they would have to find a different solution than the DMF.

where I'm going with this is to link PDK mechanical design to DMFW - LWFW discussion where using LWFW will disrupt (alter) the harmonics of the crank and result in breakage.

You're trying to make a connection where there is none.

I'll post some pics from 4.2L "Cayman X" tomorrow. These will show you guys what the factory equipment looks like on the DFI engines.

I have a 2012 Cayman R apart now and can post some of those pics as well, then we have a 2014 GT3 inbound to take apart in November, too.
