EVO Magazine - 991RS engine may be Turbo -yep that one again

[Carl_Docklands]

Well, its been mentioned many times before and put to bed many times but, EVO know this and yet, there it is inside this months fresh-off-the-press EVO Magazine, Page 18. The word 'could', it 'could' have a Turbo engine. They are fresh from the US motor show, has something been hinted at ?

EVO have good ties with Porsche infact, this months mag has two big 911 Articles.

Are we avoiding the obvious indications?

'all new engine'
'side turbo-like air-vents'
'RS Mules running the GT3 engine and not the RS engine'
'there is no GT2 planned'.

If the RS is indeed going to run a turbo engine then I label this as:

I actually think it might be turbo as well.

would be funny as owt haha.

[ThirtySomething]

I have to say seems very plausible !

Frankel was there and this was reported via Twitter 12.1.15

@Andrew_Frankel: New 911 GT3 RS will have a brand new flat six motor and, no, it is not turbocharged. #NAIAS

@rallystar944t: Brand new, as in completely unrelated to the flat 6 in the 'standard' GT3?

@Andrew_Frankel: yup.

I think it`ll be turbo , for what its worth. doesn't make sense otherwise , why not crank the 9A1 engine up to 500 and be done with it?

I don't understand; the whole point of the new engine (9A1?) was that it was 'modular' and a turbo application of course already exists. So stumped as to why they would need an 'all new' engine.

Worth noting that they said the GT3 engine was completely different from the standard Carrera lump. Actually, the engines share a lot in common.

Any idea what? Raw castings for the crank cases, few bolts and what else?

[IMIA]

Turbo engine and manual gearbox would hit the speculators a bit lol.

[APOLO1]

But, every single test that I have seen and know to has been with a N/A engine.....why would you do powertrain testing with the engine that you are not going to run in the car........? simple you wouldn't its a N/A

Seeing as their track record on all new engines hasn't been brilliant in the last decade, especially with the 991 GT3 debacle, they are brave in my view to be making such a song and dance about another new engine.

I wonder what this one will do? Rev to 9,500? Be super economical? Stop start? Blow up or catch fire? Who knows!

A fair chunk of engine internals (rods/crankpistons) were different to allow for the higher rev limit and greater airflow I think plus a true dry sump and probably a new intake. There's a thread on the rennlist 991 gt3 forum that highlights the changes to the standard engine. Quite a lot was the same but equally the important bits seem to have been changed.

[berty37]

I thought Wolfgang Hatz confirmed last week that the RS will be an NA engine and said amongst other things that there will not be a four cylinder 911 it will have to remain a flat 6 but other models except the GT3 will go turbocharged. I also read somewhere the reason they developed a 'new' engine for the RS was they had trouble reliably extracting more power out of the 9A1 unit. Knowing Porsche's conservative numbers I would bet the std 991 GT3 puts out close to 500bhp anyway.

[APOLO1]

Along with a few others on here, we were told at the GFS launch that when run in the 991GT3 will be around 500bhp, this was prefix, imv think they are over that now......

The cases, one bolt and the chains are shared between the engines. Everything else is different, this has been published by Porsche. The engines have for all intents and purposes no internals in common and are two completely different engines.

A Rennlister has explained it quite well.

So personally i don't believe this 'all new' claim.

[Magic919]

Thanks for the link. I think that's more than Andreas was letting on.

Agreed! Engine sounds like an NA screamer! Sounds good!

Correct. That's the car on the second bump at Breidscheid.
