997.2 GT3 no PDK???

[tvrfan]

Why has the 997.2 GT3 facelift no PDK like the carrera facelift? that sucks. they has should offer it as an option in the GT3 facelift!!!

2 short questions.

- will the 997 turbo facelift get PDK for sure?

- will the 997 GT2 facelift get PDK ?

997.2 GT3 use GT1 based engine unlike 997.2 Carrera models which use new 9A1 DFI engines. GT1 based 3797ccm engine is too big for PDK. Just decision that Porsche made in 997.2 GT3 models speaks enough-PDK is not ready for extensive track use yet... I not a lot more, but I can not post it here...

997.2 Turbo will use 9A1 based DFI engine and will have PDK as an option. Is it good or bad?

I can not say right now... New DFI engine is NOT true dry sump like GT1 engine and is not bulletproof design for extensive track use. There is a good reason why Porsche choose 3797ccm GT1 based engine and manual only for GT3.

will the 997 GT2 facelift get PDK too?

NO, and chances for 997.2 GT2 are 50/50 currently...

[tvrfan]

why ? i think there will be defently one. because 996 GT2 got it too. and a Turbo S version is coming with i think 520 PS (turbo facelift will get 500PS) so a GT2 facelift with increased horsepower is a MUST !!!.

so why no GT2 facelift PDK? that would be fucking awesome. i hope that porsche will get this for the next gen 911 turbo, gt3, gt3rs and gt2!

The torque is on the borderline of what the PDK can handle (325lbft).

[tvrfan]

no way dude. the 997.2 turbo facelift is going to have PDK too. with increased horsepower. even the panamera turbo has PDK and has 700 NM tourqe !!!

KresoF1,

this new Carrera DFI engine - what can you say about it? Is it good or bad comparing to GT1 block? how is it reliable and effective?

We'll have to see.

New Carrera DFI engine is excellent engine. According to Porsche info it is reliable and effective. Good for EU5 as well.

Just, it is still not good enough for usage in extreme conditions like good old GT1 block.

Still not good enough - what do you mean? overheating issues? or lower longevity?
Also will they implement changes in it while preparing it for Turbo?

BTW - as far as I see 997.2 GT2 will be based on old GT1 block differing from Turbo...

so the current 997 GT2 is using GT1 block too (as the GT3) ???

[artur777]

certainly

Not good enough for extreme usage like racing. 9A1 DFI is as I said excellent engine designed for road and occasional sport usage. GT1 block based engine are designed for track/sport usage. 9A1 is using so called "Integral dry sump" which is just very smart wet sump system, GT1 based engine is using true dry sump. For example R8 4.2 FSI, R8 5.2 FSI and RS6 5.0 TFSI are using true dry sump as well.

Interesting.
But does that mean that if you use your 9A1 DFI engine extensvely on the track you will face problems?
I think Porsche knows what they do.
If ythey decided to implement Integral Dry Sump system in it, they had smart reasons for sure...

[KresoF1]

Intergal dry sump is not a new thing-it is introduced in first 986 Boxster and 996 Carrera's.

Real reason is to cut production costs-9A1 engine is about 3 times cheaper to produce then GT1 based engine in 997.2 GT3...

It is very strange for Porsche...
Saving costs will infulence the quality of the engine an reliability
Do you agree?

Not so. Why? 99% of 997.2 Carrera or Boxster/Cayman costumers will never use their cars for proper racing.
9A1 engines are very good engines. They are designed with road use and occasional track usage in mind.

GT1 block based engine are designed as basis for racing models and here tolerance is higher. Just there are limitations of GT1 design as well. It is not DFI friendly(read too expensive for further technical development) and it is too big for PDK. Therefor GT1 production lifespan is about 3-4 years max. Current version of 997.2 GT3 3797ccm is good for EU5 without DFI... Just, there is only a limited extension possible for GT1 based engine.

New 997.2 Turbo will probably use refined biturbo version of 3800ccm 9A1 DFI engine...

I agree that most customers will never use it at the track.
GT1 is very expensive and soon will be out of the game.
Does that mean that Porsche will spend their efforts to improve this new 9A1 engine block to improve its track reliability for future GT3/GT2 cars?
Or will they make absoultely new generation of GT1 engine block for fututre cars?
