Final Batch of 3RSs and Speedsters - Do They Have the PF?

I’ve opted for GTSM, WP, Mag wheels, PCCB, lift and a few everyday driving essentials. I struggled adding weight having paid a chunk to make the car lighter. Clearly, with my limited capability it will mean zilch.

Makes one feel good though, I agree - go as light as possible (I would not even take lift, but then I don’t mind constant scratching noises .....)

Enjoy in good health

I suspect here is your answer to GPF on Speedster and 3RS:

I wonder if we will see these same engine modifications on the EU GT3 RS ‘batch 2’.. and the RS will have the ram air effect to raise BHP.. plus ITB’s would be an awesome bonus!

Can you get the brake calipers in a different colour via CXX? I would get rid of yellow and go for silver with silver stitching if available on a black car

That's got me thinking What colour would you go on the Mag rims..?

It's hard/impossible to get different brake caliper colours unless your name is Porsche or Piech. Bit daft as obviously silver is a standard caliper colour on other Porsche cars.

I'd definitely be more tempted to go CXX on the wheels. I know it's a .1 but a homage to the 997.2 RS works pretty well (got the mirrors and door handles wrong in my book)

On a black car, I would be going yellow callipers and yellow stitching with white gold mag wheels.

Probably still that gold color or silver - silver less in your face , do like gold though (possibly with black calipers)

Is it possible that they would change the spec of the second batch cars to the same as the speedster? It would be fantastic but it seems a little bit of a stretch to me.

It seems the only logical solution right now..

[hunter 66]

Maybe it will be a 991.3 RS , with a 4.2 , 600 bhp and mega phone pipes ..... that would be cool

[NoPDK]

Here’s the confirming paragraph from article above, it relates to the Speedster engine, but surely must also apply to the OPF GT3 RS for the EU:

However, it maybe a stretch to think the Speedster engines ITB will form part of the solution for the RS as well... we’ll know very soon I’d think

[DT398]

I guess it’s possible that the second batch of RS will get the throttle bodies but it’s obvious from the comment above that the filter will impact the sound if they can now get away with one muffler instead of the three. Can’t imagine it’s going to sound bad though!

[RBT0]

Good news is they’re reducing number of muffler to off set gpf i.e. they want to keep car loud. Guess the same will apply to GT4.

Getting rid of both side mufflers will counteract the weight of the GPFs..It will also reduce heat on the rear tyres...Its looking increasingly likely that these ITBs and single muffler exhaust will be applied to the second batch RSs..

ITB’s would be fantastic but might be wishful thinking. The exhaust changes sound realistic though.

I think they'll come as a pair..It seems that the ITBs help reduce emissions when cold right at the time when the GPFs are at their least effective.

If the above thinking is true, why isn't Porsche more open about it?

It'll be interesting to get confirmation of the RS engine specs for someone like me who loves all the techie details

As all the pieces of the jigsaw start falling in place the above scenario is the most likely IMO..Porsche would never ever release the official engine data in WLTP mandatory countries until the RS or Speedster has actually been approved by the WPTP tests.

[DT398]

I think “increasingly likely” is a bit of s logical leap at this point.

The ITB could be a point for Porsche to use to differentiate the Speedster, which is a brand new model and I’m sure the cost is not insignificant.

The exhaust on the RS is also titanium and not the same as the regular GT3 on which the Speedster is based which may or may not be a factor, I don’t know.

The Second batch of RS is exactly that, a second batch of existing cars that has some additional options. Under normal circumstances these would be indistinguishable from the first batch but the emissions testing has got in the way, making it a bit more complicated.

If they had added the ITB to the remaining run out of 991RS as an enhancement, it would be very unlike AP not to mention it! Will probably see it on the 992 at least.

My bet for the remaining RS: same engine, filter, less muffling, same power, pretty much the same noise.

There’s a post on Rennlist where a guy has a Swiss car coming and the spec mentions the filter.

Edited to add: the plot thickens. It looks like the Swiss car is specifically without a filter? I give up. Let’s wait and see, but I’m changing my bet to same set up in the last batch, no filter.

[Twinfan]

Exactly. The silence from Porsche on the subject is deafening - surely they're not planning on avoiding the regs and releasing unfiltered cars???

[DT398]

They’ll be compliant with regs 100% but will have an arrangement to allow them to supply a final few cars without the filter as a follow on of an existing model imho. They couldn’t do that with the Speedster as it was a new model.

Same motor, no filter for the remaining RS imho.

[Twinfan]

That's possible I guess, but all the info I've seen is that end of run cars had to be built prior to June 2018 e.g. for mass volume manufacturers with unsold stock cars. It doesn't, or didn't, apply to new builds unless something's changed, but I'm not sure why the rule makers would allow it.
