Minimally, the bottom and the shiny side are still all original

 

I sure hope this is the case so I can get one. Been a painful experience so far trying to obtain one.

 

You can't just divide the increase in diplacement by the original displacement and expect to get the exact power gain. xD

 

How so? The 4.0 is 295-300 co2 i believe
Whats the limit

 

No idea but AP has said directly the 4.2 wont pass and they aren't going to pay for another NA engine for a limited run of cars.

 

Yes, at this level you pretty much can. If you increase cylinder size too much (large displacement increase without increasing number of cylinders), then you risk not being able to rev as high which reduces specific output. You can think of a proportional gain in torque and power as a best case scenario.

 

The .2GT3RS will be a 4L engine with another 10hp or so.

 

No hybrid? similar to GTS

 

Strongest rumor is no. Will be NA until at least the 994.

 

a 4.2l could be again in 20.000 cars.
how many of the current 4.0l where built since the 991.1 GT3RS? (which where all somehow similar, all those 4.0l variants) i guess we are already above 50.000 even above 70.000 4.0l engines since the 991.1GT3RS.

4.2l development costs: 200Mio would be "just" 10.000 USD per engine (with 20.000 units). But within EU nobody knows what will happen after Euro 6a - so what will be legal after 1.1.2028 is not sure.

 

Are you saying they can use the 4.2L?

 

I strongly believe its gonna be 4.2. They maxed everything out.

For the 994 GT3 it will be 3.6 10,000rpm 6xx HP hybrid.

Porsche needs to keep pushing to be on top.

If Ferrari, Lambo and Aston can keep making high displacement cars, Porsche can too, esp with all the EV cars rolling out.

Got inside info from a employee at Porsche the next GT cars will have a heavily reworked exhaust to be emission compliant. We are also seeing it on the test mules.

 

I think so as well. I don´t see any other choice to be honest. They´ve pushed the 4.0 to the limit with the 992 GT3RS with the aero and engine. As well as shorter gearing.

Interesting to remember that a simple ecu tune and exhaust on the 4.0 will give 550hp and 510nm making the engine breathe and run better the way it is supposed to do with a much broader torque curve and powerband. They have to restrict it to pass emissions per Andreas P own words. Using the same principle with the 4.2 (if they use it) the numbers should be around 545hp and 505nm and with a tune and exhaust closer to 580hp and 535nm. The main benefit would also be the much more broader torque curve and power band.

Do we have info on when we can expect the announcement?

 

Car is already way too fast as it is, and I mean that genuinely.

 

Adding 200cc (5%) displacement will only raise the RS’s torque from 465Nm to 488Nm without raising compression or making some kind of breathing improvement (and you just said the emissions restrictions are going to be tougher).
