Taff after all this s—t about getting one,you will get rid of it for a blower and because its 20bhp less,which you will not notice mate.
Do the honourable thing and give it up to some one who really wants one
Sorry Paul about all the s--t i i've spouted recently.I was under a great deal of pressure..Do the honourable thing and give it up to some one who really wants one
I'm only joking about chopping it in for a 992TTS...Off hand i can't think of anyone i know who really wants one more than me.
I can solve the GPF in ten minutes with an oxy-acetylene which i'm more than happy to do for anyone else for one off special price..robgt3 said:
Surely removing the GPF will blow the warranty clean out of the water. Plus won't the ECU need a re-flash to compensate for its removal?
Well the first part is easy, put it back on before making a warranty claim.ECU re-flash is my concern. Time will soon tell.
I do know that Dundon motorsport has an amazing combo of full exhaust and upgraded reverse dual cone airbox which increase filter area by 353%. More filter area means slower air speeds through the filters and less pressure drop across the
Thee full exhaust inc headers, not including the airbox:
445whp Peak
32whp at 8400rpm
29lbft, 24whp gains at 4478rpm
Assuming all is ok, I will be going for a Dundon system or JCR.
Seems like speculation is based on PPF/GPF being way down the exhaust tract in a place that can be easily removed aftermarket... From what i have read, there are a number of implementations, including from within VW group, where the PPF/GPF is now the new first 'catalytic converter' in a multi-cat system - As it needs the high heat of being ultimately as straight out of the engine exhaust tracts as possible, an proximity to the engine, to burn of the smaller offending particulates and regeneration.
Removing this may not be straightforward at all, will there be any ECU integration with RPM limiting until you reach warm-up temp? All this let alone concerns about warranty.

To add insult to injury i've also heard that the 718GT4 has had the NA engine dropped for the production version, to be replaced by a 3L Turbo from the 992..
I’m less surprised by that than the news a few months ago that it was going to get a de-tuned version of the GT3 engine. Owning a 981 GT4/Spyder is a good place to be. TDT said:

I think you're bang on..Porsche originally tried to utilise the same 4 way cat as the 992.It apparently works well on he 992 and as they've re-sited the intercoolers so that the 4 way cat can be situated right next to the Turbos..Porsche are experiencing pretty much insurmountable problems on the RS as the engine is already at its peak specific power of 130PS/L, even without a restrictive GPF.Removing this may not be straightforward at all, will there be any ECU integration with RPM limiting until you reach warm-up temp?

That would also be without the GPF adding increased back pressure at higher revs.
It sounds like the second batch RS and Speedster may be sharing the same GPF engine? That would make sense to me, as would the 20bhp loss, but I'll readily admit I'm no expert.
The 718 GT4 getting a turbo engine wouldn't surprise me, but it would seem to go against all expectations.

The RS may still be rated at 520ps because of Ram Air Effect of the side intakes and freer flowing Ti Back box.It sounds like the second batch RS and Speedster may be sharing the same GPF engine? That would make sense to me, as would the 20bhp loss, but I'll readily admit I'm no expert.

The Speedster doesn't have these (defo not intakes..didn't see anything about the back box) and is rated at a similar 500(502ps) to the GT3 which also doesn't have the side intakes...so no HP loss. Maybe only sound.
It's a drop-top GT3.. not drop-top RS.
Having re-read - we are saying the same thing. yep.

I dissagree. Given the price, the hood design with the swage lines, the hood, fenders and quarter panels in carbon fibre, and the 346lbft of torque id say its an RS in drop top form not a GT3. Loosing the intake rams may have dropped it from 520 to 502hp but thats still more than 500.
What intrigues me most (apart from how/if thay made it Euro 6D compliant) is the individual TBs from the Cup car. This is a sure sign of what we will see next time in the GT3/RS?

Are we all make wrong assumptions regarding the launch spec Speedster having the EU legal GPFs fitted. The Speedster was launched at the NY show so its quite possible it doesn't have the filters.I've read all the press releases and never saw any mention of the GPFs.What intrigues me most (apart from how/if thay made it Euro 6D compliant) is the individual TBs from the Cup car. This is a sure sign of what we will see next time in the GT3/RS?
However i might have missed it in which case i apologise in advance.

Ok yep. I can understand that.… I stand corrected. What intrigues me most (apart from how/if thay made it Euro 6D compliant) is the individual TBs from the Cup car. This is a sure sign of what we will see next time in the GT3/RS?
