You drank the Kool Aid didn't you?

I went from a T to a GTS. No discernible lag. It's all anecdotal or psychological. No one can really put down numbers on how fast each turbo spools up and how much that specific turbo has on the power curve. People seem to think they can tell but they don't know if it's the turbos or just the power curve of the engine and mapping. I have yet to see anyone give facts on this.

And as far as the comment on putting a 48v motor in to compensate for lag on the S. Really? Are we trolling?

Someone hasn't been keeping up. The turbos will be electrified, spun in part by an electric motor to minimize turbo lag. It should be a substantial improvement in responsiveness: certainly the 400v version will be, but even the 48v should be noticeably better.

Yes my opinion. When I hear these guys bragging about their "gated" GT3 and how much markup they paid to get it, it makes me barf. Since when did a manual transmission Porsche become "gated"?

Porsche keeps raising prices because there's this whole new breed of customers it has found. Porsche isn't living off retired physicians in their 70s and 80s.

It's a big coincidence as I've gone from a 2022
GTS to a 2024 T and I think T feels much more agile and responsive! If you're all with specs and numbers, yeah you should go with the S or GTS or whatever.

The 992.2 S will come with the 48v motor, if you like it or not.

😂😂😂

You brag because you paid a 100k ADM. I brag because I paid MSRP. We are not the same.

zachr

Didn't you also say no one would notice the steering difference between a GT3 with double wishbone and a Carrera with struts on the street? Sorry bud, your opinions aren't exactly trustworthy.

Ikone

No, that's not what I was reading. I was reading the original comment to be stating that this is to fix the 'current' turbo lag of the S.
Anyway, keeping up with what??? All the rumors or do you have some official source that there is an 'e-turbo to compensate for lag on the S'? Exactly. You don't. So please stop with the 'keeping up'. Sheesh.
Until it's all official, no one really knows.

Ikone

Good for you.

And I don't think I gave an opinion on the 48V, but glad you are responding to something that I didn't say.

997.1 S was 3.8 and base was 3.6

I had an S... absolutely 3.8

Turbo lag isn't S-specific, it affects every car with a turbocharger.

And, like...of course they're doing this to improve turbo lag, dude. Why else would they do it? It's not like e-turbos are going to improve fuel economy, nor help the car make more power at the top end. The press releases from Borg Warner make a point of explaining that peak boost is achieved 50% sooner or something like that. By the seat of my pants, I'd guess it's going from about a second down to half a second.

This also aligns with the oldest rumors from Car & Driver, that there would be a "T-HEV" model. Turbo hybrid. Obviously C&D had the implementation completely wrong (shocker), but this rumor seems pretty well substantiated at this point. But sure, we'll see next week

edit: to be clear, they're only not doing this on the Base because of money. It's not because the standard Carrera has much less turbo lag or anything like that. It would benefit similarly from this treatment.

Ikone

Okay, not trying to argue here, but....lol. jk.
Where are the numbers on lag? I've always wanted to see the numbers between the base, s turbos. I keep hearing about lag, but honestly, I'm not sure if what people are feeling is actually turbo lag. I used to drive a WRX. You wanna talk about lag.
I won't get numbers or stats, I'm sure, but there is a lot of anecdotal evidence and psychology playing a role here. We need some of these folks to do some blind tests. lol

zachr

I just realized that I do have some real data on this, via data logs from the M-Engineering dongle. Spot checking a few pulls, it is indeed about a second from stabbing the throttle to achieving full boost. It takes about half a second to get “close” (75% of ~peak), and another half second to get the rest of the way there with the M-Eng stage 2 tune on my GTS. I have no clue how much of that is programmed in versus being as fast as the turbo can manage to build the boost, but there’s some real data for you.

Maybe one day I’ll do a log on the stock map and see if the lag is comparable. If someone with a base carrera and the M dongle is willing to do their part, that might motivate me a bit more…

Ikone

Ah. Okay, so the dongle gives you stats on the boost (tracking it)? This would be interesting to see from base, S, GTS.

RatherJaded

I still own a 997.2. I was confusing the 997.1 displacement with the prior 996.

zachr

Yes, though it’s not exactly automatic. You need the dongle connected to a PC with the logger configuration provided by the folks at M. For anyone looking to do this, I’m using the Time, Target Position Throttle, and Manifold Absolute Pressure columns, and calling it “peak boost” when MAP is within ~100 of the local maximum for the pull. The logs I’m looking at start around 4500rpm. I assume the lag would be much greater starting at, say, 2500rpm and locked in gear. That’s also the situation where e-turbos will make a huge difference.
