Litchfield adds 200hp to 992 Carrera 911

Stage 1 map takes outputs of turbo flat-six to 580hp with no hardware changes

---

Litchfield has launched a new Stage 1 map for the 992 Porsche 911 that can extract a further 200hp from its turbocharged flat-six engine. The Litchfield software, which reduces emphasis on emission control to maximise performance, pushes total output to 580hp for both the Carrera and Carrera S models, making the entry-level 992 as powerful as the 991.2’s most potent model, the Turbo S.

Naturally that power gain is accompanied by a big growth in torque, with maximum twist now set at 480lb ft – 90lb ft more than standard. That being said, Litchfield’s changes do make the 3.0-litre boxer a tad less rev hungry, Porsche’s flat power curve swapped for one that begins to taper off towards its top end. The drop in punch is tiny, however, showing that you'll still be rewarded for letting the motor rev out.

Interestingly, Litchfield told PH that both the Carrera and Carrera S share the same powertrain hardware, with the former model only losing out from the factory due to its digital settings, meaning bringing it into line with the S requires no extra work.

Now that Litchfield has launched the Stage 1 map with a price of £1,194, it anticipates a week’s wait for customers wanting to get their new 992 (or a used one) on the Gloucestershire firm’s rolling road. The company is also working on a higher-spec upgrade that will include the option of a different exhaust system, supplied either by Remus and Akrapovic to free up airflow, reduce weight and enhance noise. Should you just want the latter for your 992, a less restrictive silencer will also be available for otherwise standard cars.

Elsewhere in the Litchfield garage, engineers are working on an upgrade for Audi’s latest RS4 and RS5 models. Although the tests are ongoing, Litchfield told PH that we’ve only four to six weeks left before final stats for the fettled 2.9-litre biturbo V6 are confirmed…

That's a pretty impressive performance gain for the money...

[WCZ]

this is a huge deal imo, I had no idea the base car was this detuned from factory
when the warranty periods all run out then there's no real point in an S
it's thrown a little bit of a spanner in the works regarding my intertest in the upcoming turbo s too.

Yup. 200bhp for just over a bag of sand. Bargain.

+200hp from a £1100 map, what a time to be alive!

meaning low rev performance is actually down on standard.

Not according to the graph?

Forgive my ignorance but are they RWD? 580hp will be a tad "spikey" on the road if so!

TX.

[PS2018]

agree with @WCZ this is an astonishingly detuned engine as standard then, if 200bhp can be freed up that easily with a re-map

[RumbleOfThunder]

Actually looking at said graph, the "crossover" for power and torque doesn't seem to occur until 5200? That is a dramatic change to the characteristic of the engine, not one I'd probably fancy.

'The differences between the new base Carrera and the Carrera S aren't huge. The engine in the former uses smaller turbine and compressor wheels within its two turbochargers and runs lower boost pressure.'

Perhaps not strictly true.

But most people who buy this type of car will probably go for an extended warranty anyway. Unless of course your are wealthy enough not be care if something goes horribly wrong.

Plus, I'm sure the 992 `Turbo` & `Turbo S` engines will be more than a remapped ECU from Porsche.

Still. As an ultimate sleeper, this car ticks huge boxes, and no doubt whoever goes for this remap will have one seriously quick car.

The real Grey area, and one I disagree with, is people getting a car on PCP, tuning it up, then putting it back to standard just before they hand it back. The next owner then has the potential costs of something going wrong, as extra strain has been put on parts that shouldn't have had.

I'm interested in the new turbo S but quite frankly at the price i'm going hearing it's going to be I don't think I'll be able to stomach the price difference if the standard engine is actually very similar to it but heavily restricted.

Power and torque always crossover at 5252 rpm.... if you look at the graph, both the OEM power level and the remap both cross at 5252.

[PS2018]

thats a good point @wab172uk and its not like an over-rev report would necessarily show that, would be hard to tell unless OPC spotted it when servicing in the meantime (they surely would when plugging in diagnostics?) so one would need to get it serviced at indy's throughout the pcp term?

I think I've misread the graph the same way the writer has.

This.

I would be interested to see a side by side comparison or some stats for the mapped one because it is down on power all the way to 5200.

I wonder how much that changes the driving experience.

Are you seeing a different graph to me (or am I reading it wrong)? It looks up on power and torque across the whole range. The standard car makes peak power at ~7200, the remap start to lose a little up there.

PH isn't Instatt or ttter you know

[Addymk2]

Are people misinterpreting that dyno graph?

To me it looks like it's up in both power and torque from the get go. There's no real change in engine characteristics, it's a linear powerband all the way to redline...

After looking at it on a monitor rather than a phone... yes you are correct, I retract my statement.

[RumbleOfThunder]

Yes some of us are misreading it . I took the two lines starting at "Litchfield" to be Litchfield's map, but looking again that doesn't make any sense. The characteristics are in fact very similar, which makes much more sense given the hardware is the same.
