Well spotted. ;)

Thanks for the clarification. :thumbup: But a/c delete (9X6) does not have this button, does it?

How does the 997 windscreen defroster work? The button I'm talking about has a sign of a curved shaped window (In this pic, it's just on the left side of the 'heated rear window' button - square shaped window). Is it true that 996s did NOT have the windscreen defroster button?

Please enlighten me. Thanks.

As I recall the GT3RS engines are built at Porsche Motorsports

Anyway, I've just been reading the article about 2010 GT3 in the latest Excellence mag today. It says the crankshaft is now shot-peened for extra strength.

So, maybe that's what it is. Could anybody verify whether RS cranks were shot-peened? I really need the part number of RS crank.

1. Does 997.1 RS crankshaft have the same part number as the non-RS 997.1 GT3?

2. What's funny is that the Technical Info Service above states 'As of 2007'. Does this mean only applies to 997, not 996?

Here's the expanded version of the PCNA bulletin. I wouldn't do it...

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.

Why is it okay for an RS engine to have a single mass flywheel, and not standard GT3 engine? I thought these 2 engines were one and the same?

I have been trying to find this part number but to no avail. Help would be greatly appreciated. Thanks in advance.

Was the Mk2 owners manual scanned? The quality was so good, I don't think it was scanned, more like dowloaded from Porsche.

Hello,

Does anybody have a link to download the Mk1 GT3 and 997 GT3 owners manuals (in pdf)? I have already downloaded the Mk2 manual from this site but somehow Mk1 and 997 are not there.

Thanks in advance.
