LWFW question...
#16
Is your entire quote coming from your mechanic or you?? It's funny cause you start of with "After talking with my mechanic my fears have been put to rest" and you say in your last paragraph "I would challenge anyone to come up with any actual documentation from Porsche stating that the use of the factory single mass flywheel on 996 GT3 will void warranty in the event of motor failure".
The motor in the topic is a 3.6 X51 with 345Hp which is 35HP less then the GT3 . Yes the wet sump engine came from a derived version of the boxter engine but you can't really compare. Heck you can't even compare the 3.4 and the 3.6 so why imply that the 3.6 is just a poor little boxter engine??
Did not mean to offend your sensibilities.

are you still under warranty...and if so, did the dealer tell you that putting in the RS flywheel would be covered...trying to determine if the Porsche service bulletin that stated that RS flywheel installations will void warranty was specific to 997 GT3 and does not include 996....

my dealer service tech is on that other forum...I'll pm him and see if I can get it but he is the source of the info...when he was talking about it (just last week)...it was specific to the 997 but I assumed that was because that is the current iteration...if you brought in a 996 today and asked for the rs flywheel it would be interesting to see what the dealer would say....

for those, "I'll believe it when I see it guys"...
Technical Information
Service
36/08 ENU 1360 1
GT3 Engine: Flywheel and Pulley
Vehicle Type: 911 GT3 (997)
Model Year: As of 2007
Concerns: Flywheel and pulley
Information: Replacing dual-mass flywheel with single-mass flywheel.
We have discovered that the dual-mass flywheel, which is installed as standard in the GT3 engine (vehicle type 997810/-811), is being replaced in the dealer organization with the single-mass flywheel from the GT3 RS engine (vehicle type 997850/-851).
Information
Due to an increasing number of reported faults, we expressly wish to point out that the installation of the single-mass flywheel (from the GT3 RS) in the GT3 engine is not approved by Porsche.
Since the 911 GT3 (997) engine application is designed for the dual-mass flywheel, conversion to the single-mass flywheel results in the following problems and consequences:
• The single-mass flywheel causes fluctuations and vibration in the lower rpm range, thereby reducing the smooth-running performance of the engine.
• The crankshaft is subjected to one-sided loading, causing stress peaks that can result in damage to the crankshaft.
• The one-sided loading of the crankshaft can cause the pulley to come loose, resulting in damage to the belt drive and engine.
• Any damage relating to conversion or damage that can be attributed to conversion is not covered under warranty.
Please advise your customers of this information accordingly.

I don't know why you are getting out the popcorn...that is a copy of the service advisory sent out by Porsche...it's not from me....as far as I know there are only slight differences between the GT3 and GT3RS engines and the dual mass fw (GT3) versus single mass flywheel (RS ) is one of them
