^Makes sense. Thanks for that explanation.

I wonder if there may still be something else going on with the different exhaust tips...

 

Really? Oh you mean marketing that you gotta buy the next VIP car if you want a limited car in the future. It's even worse than getting blue *****, it's like....hey, look at the cool thing that you can't buy.

 

AMS in GER say its a 991.2 GT3: http://www.auto-motor-und-sport.de/n...-10528934.html
they say it will stuck with 3.8l N/A and probably 495hp

I can´t imagine that the 3.8l will be squeezed out a bit more for the 991.2.
If 991.2 GT3 I could imagine that the 991.2 GT3 will also get the 4.0 RS-engine (detuned to 485hp)... Or the 4.0 in the 991.2 will not happen - because the 991.2GT3 would be than too close to the 911R and the 911R-buyers will be pissed off.
But if 4.0 in the GT3 --> the 991.2 GT3RS would go turbo (no GT2 or GT2RS would follow).




Questions also interesting for the 911R:
What are the differences of the 3.8 and 4.0 engine in terms of size, packaging, mounting?

We heard in this thread that the 4.0 needs more cooling - somebody knows details?

 

This mule is not the R.
R = carrera 2 body Shell

 

I'm thinKing same as you.

There is more in 3.8l engine if they want it. It is only 30 BHP more than preceding Mezger 3.8 GT3 unit and with higher rpm and DFI it surely is not yet run at full efficiency. Especially when torque hasn't moved by more than 10lbft. Charles Dunson has managed to find 45 BHP/29lbft peak (I.e 510 BHP) by tuning the ECU and building equal length headers without cat. The factory must include Cat and has noise constraints but there is definitely 20 BHP/12lbft left on the table with an exhaust re design and ECU tuning.

But I would be surprised if they will run the 9000 engine out to its potential as there is bad press here from their earlier exploits.

After owning the C4S bodied 991 GT3 I'm not sure I could care so much for a narrow body as the only benefits are higher top speed which I will never use (only been to 270 kmph in this car on autobahn once).

 

Hi Mark:

When you come do Germany we go for a > 300 km/h ride
I know the proper roads for this
Peter

 

That might be the case for some but most will still want to see it. It's no different then some of the elite companies showing off their unobtainable cars like the La Ferrari, Bugatti's, etc....

 

I still believe it's the next GT3. Only this time around they're going to do their homework with the possibility of squeezing more hp out of the 3.8 or if they don't feel confident in it, drop the 4.0 in. Maybe that's why we're seeing two different mules out and about.

 

When do think the 991gt3.2 was originally scheduled to be released? Would seem likely as a 2017?

 

Not Exactly. Your not leaving Porsche, are you? They get you excited about the brand to buy the next closest thing. It's not like this is a new business model for them.

 

I think shown at an Auto Show in the Fall of 2016 as 2017 Model Year is still likely with RS the following year. Probably some further limited edition model to close out the NA era as 2019 Model Year.

 

Exactly. Porsche is not one to mess with the tradition. GT3 models debut a year after the new or updated Carrera model is launched. RS model will launch a year later. Need to offer something newer and faster each year.

With around 4 years production left in the 991 generation, that lines up nicely with Porsche offering a GT3 RS 4.0 equivalent the final year to close out the 991 generation and possibly mark the end of the NA engine.

Expect GT3 offerings to go something like this:

2017 991.2 GT3
2018 991.2 GT3 RS
2019 991.2 GT3 RS 4.0 equivalent
2020 992 introduced
2021 992 GT3 (NA or Turbo, it will keep the GT3 badge)

 

Spot on in all regards!

 

I love my 991 GT3.

I don't care about more horsepower, I want more torque.

If Porsche can provide at least 12 or more additional ft-lbs of torque in the 991.2 GT3, then I will upgrade. However, if they only offer apple car play and another 20hp as the main upgrades for the .2 GT3, then I will just keep my current .1 GT3.

I agree with Mark in that there is more torque to be had from the GT3 engine if they do some of the tweaks that have been posted on this forum. Whether or not those changes would reduce engine reliability is another question.

I still think Porsche will move on from the 991 GT3 engine and all the money it has cost them. I expect they will drop the current RS engine (4.0L) into the 991.2 GT3, detune it slightly to 495hp, (but with an additional 12-13 ft-lbs of torque compared to the current GT3 engine), keep the current 4.0L 8600-8800 redline, and then the next year Porsche will max out that same 4.0L engine to 520-530hp for the 991.2 RS

 

I'd be surprised if you'd notice the extra 3.7%. If you want more torque, might be more effective to use lower Ring & Pinion (gearing is a torque multiplier). Is there an option available for lower final drive (one from RS or Motorsports maybe?).

If the 991.2 GT3 has a 4.0L, then torque should go up on average about 5.3% across the rev range. Although the official specs show the RS only making 13 ft-lbs more than the GT3 on the website, I bet the difference is quite a bit more on a percentage basis from idle to 8,800 rpm. I bet the peak numbers being less than 4% apart is a bit of an anomaly in the shapes of the curves.
