GT4 Technical Documents Thread
Now that a good number of cars have been delivered and being driven appropriately, it may be time to look a bit behind the marketing curtains and unveil the true contents of the GT4.
Here is an attempt to collect together community knowledge about all things technical. Such as the "service information technik" here.
Now, if someone has the parts list (GT4 PET) that would be a great step forward.

not so happy to find this ..... what's the deal with this "Integrated Dry Sump" idea (BS!?)
and Evo interview with AP - comments that it's 'no problem running slicks and having hi g-forces'
even in the (thanks EBS!) doc above...

In case you don't know,the GT4 comes with a plain old Jane Carrera S 3.8 engine. It has an integrated oil sump,which is fine for track use and covered,as long as you don't use slicks. All for 80K $. You want to go racing and use slicks,buy a Cup car.

um ... ok Neaincu - I think we're talking across purposes
... just saying the documentation says "no" when AP said "yes".
He also mentioned the "Integrated Dry Sump" ... try searching those words in the document kindly linked above .... the word sump doens't even make it in once!
ps I am aware of the 3.8 C2S engine - it was on my order form!
.. and yes I do race a nice old cup car on slicks once in a while

Unfortunately,you will not interact with AP if a warranty claim has been put in place by your dealer. It will come down to your dealer,the relationship you have with them and Porsche's goodwill. I don't know how they'll know you have been using slicks...perhaps they can read the yaw inputs in your DME...again,I don't know...
The Carrera S 9A1 3.8 L engine has proven to be quite capable of handling track usage...even racing...please see several threads put out by BGB motorsports,where they have stated that they have raced this engine successfully. So " integrated sump or not "...it certainly seems it is capable. It might even be capable of handling slicks,it's just that Porsche won't cover any damage of doing so...

But I get your point : the engine might be capable of handling the extra stress from high cornering loads provided by slick tires.

Page 15, DME engine electronics ... Anyone else find this odd?
"A 3.8 l engine is used in the new Cayman GT4. This is based on the 3.4 l mid-mounted
flat-six engine of the Cayman GTS."
I thought the motor is basically that of the 991S but slightly de-tuned? I know they are all some derivative of the 9A1 platform, but still ... why state that the motor is derived from the GTS rather than the 991?

The Carrera S uses a 3.8 engine making 400HP,which is the exact same engine used in the GT4.
