If there was a time to buy a naturally aspirated 911, it would be now?

Anticipated end to an ERA, what do we think!?

It'll be terrible, obviously. After all, what do Porsche know about designing and building turbo engines?

For me the compelling proposition is the Carrera S with the proposed 3.8 + Turbocharger at an estimated 530bhp.

Also, it eradicates the continuous debate surrounding Porsche 'holding back' the power of the Boxter/Cayman due to the impact on the 911 sales.

I wonder if it will be twin turbo in an attempt to keep decent throttle response?

One of the disadvantages of turbo flat engines is the relatively long intake tracts if both sides are fed from a single turbo leading to poor throttle response.

A turbo on each side is much nicer.

Cards on the table, I dont want it to be turbocharged BUT...

Will you be able to tell? Modern turbo systems are getting very linear in their delivery and are nothing like the 'NOTHING....BANG' delivery of yesteryear. I have driven a few cars recently where I honestly couldn't tell! Mind you, they were still crap.

The throttle 'response' is electronic anyway, so what difference is there?

The noise is the problem. Today's 911s, as with all modern cars, are fairly boring because they remove you from the noise, feel and smell of older generations.

The newer Turbos are even worse; you can't tell it's a flat six... in fact... you can't tell it's anything; it's just an engine (and therefore my argument of the loss of the Mezger being no great loss at all).

So, to get round this, Porsche will have to use fake engine noises, surely? For shame...

I'd say if you have a manual 997.2, keep hold of it!

Surely one of the great attractions of Porsche is their invention, adoption and use of new technology. This seems to be the way forward, smaller more efficient and powerful engines.

I've not driven the new turbo yet but if the M4 is anything to go by the the noise will be the issue. But I do like the idea of a 400bhp std 911!

The throttle response, even if electric, simply isn't as good as the air needs to be compressed by a turbine and pass through an intercooler before it enters the engine. There is still some 'lag' as the turbo spools up (even with small turbos and variable vanes).

All quite shocking... Even Ferrari are going this route from next year (or now with the California).

The end of performance cars as we know them -- and the noise a NA screamer brings.

End of a glorious era, hopefully the GT3s will never be turbo'd.

Is the source from Porsche?
Gen 2 should be the power kit version based on how Porsche have operated for many years.
Will the whole range now be called the 911 turbo?
Appreciate regulations etc but hope this does not happen even on the 991 turbo I didn't like throttle response compared to the C4S I drove not even going to talk about sound.

If a standard Carrera is going to be 400hp, I doubt very much the 'S' will be anywhere near 530hp - more likely a misprint of 430hp!

Like any engine, turbo or otherwise, noise is a factor of exhaust suppression - look at any lightly tuned R32, R33, R34 Skyline, they can make delicious 6 pot noise. The fact that Porsche choose to subdue their engines is merely a shame that can easily be overcome with an aftermarket exhaust.

Agreed on all accounts, but in the end, isn't noise simply a form of wasted energy?

Wouldn't a 100.00% fuel efficient engine, something that cannot exist for too many obvious reasons, be completely silent?
That logic (if it is completely flawed please point me in the right direction) is why I think engines will become somewhat quieter as they become more efficient.

Why do I feel the sudden urge to go buy a 6.2L C63... wink

it's all about linearity of response. turbos just can't match NA for response. And that's what i think we'll be missing the most.

So from what is being posted the 991.2s will be the 991gts engine and the base 991.2 will be a even smaller more powerful lump and maybe turbo 2.9 with the 981.2 following with a detuned 2.9 turbo for the S circa 380hp and maybe a flat4 for base models circa 290hp

430 which is the powerkit and 530 would make the 991 turbo redundant and would need stronger brakes, suspension etc..

Sound can be made better but nothing compared to what a NA can do.

So the Gt3 RS may well be turbocharged? Yes or no?
