The whole lag thing is really insignificant in my opinion on the 911.2. It's not like 2.0L tuner engines with GT35 turbos that don't spool up until 5k rpms. The GT3 engine only makes 346 lb-ft of torque at 6000rpm. A stock base Carrera makes 330 lb-ft at 1700rpm. A tuned base Carrera will be pushing 440lb-ft at 3k rpms and it'll stay above 350 lb-ft until around 6.5k rpms. So basically, a GT3 will be slower anywhere below 6.5k rpms. And lag will be in the couple tenths of a second anywhere above 3k rpms I bet.

This is an interesting comment. When I drive a GT3 and my Carrera T back-to-back - which I've done a few times - this is really what I notice. The GT3 is high-drama, you wring it out to get the best part of the engine's powerband. It's a super entertaining platform, for sure. And then when I jump back in the Carrera T, the powerband just feels so natural and seductive. It "feels" just as fast as the GT3, if not more so, and it has a character that is incredibly balanced. The 3.0 9A2 T engine is a marvel of flexibility and perhaps the best street engine Porsche's ever developed.

Then there is my old 993 - I had a '95, without varioram - so it had the classic 911 NA Off-cam, On-cam behavior. I always loved the "kink" in that engine's powerband passing through 4K RPM. In my mind, having not driven a 993 and GT3 back-to-back in a while now - the 993 I remember sits somewhere in between - it was definitely a dramatic engine - but the power difference between the modern cars and the 25 year-old 993 really shows today. It would be very hard to go back from a power standpoint, but the aesthetic enjoyment factor is there for sure.

honestly i LOVE my T. but this just isn't true, even subjectively.

as someone who owns a T and has significant experience in a track format in a GT3, my guess is you are not flat in a GT3 if that's what you feel. there's just no way.

in a straight line on the street, sure. but that's virtually any modern car that's running <4.0 seconds to 60.

over 110 mph on a straight, or an 80-120 pull, or lateral grip. there's nowhere a T is comp'ing against a GT3.

what you're referring to is quickness. not speed. quickness is a one trick pony. speed is holistic.

You are right - I'm referring to street speeds, not track. I've not had the chance to put them back-to-back on the track. On the street, 20-50, 30-70, this is what I'm feeling. I certainly wasn't putting down the GT3, just commenting on the way the torque curves in these cars contribute to the driving experience on the street.

lamacan

you are correct. at street speeds below 70 mph, and with no launch control being used, the T will "feel" faster because it gets where it's going with less drama due to the torque band.

90% of GT3 drivers are using 10% of the car on the street. and best case scenario using like 70% of its ability on a track. very hard to get to 9/10ths in a GT3. pretty easy to get to 9/10th in a T.

the T, in my opinion, is the swiss army knife porsche. every time i do something new with it, a new road, a new track, i love it more and more. it's not the best porsche at anything. but it does everything you can throw at it very very well. the renaissance man of the 991 lineup.

Thank you for the kind words! Our team of fabricators really are artists and they put a lot of love into the fabrication of the headers. You can see it in the quality of the welds and internal porting of the runners and merge to remove any little obstructions to the flow. Equal length headers are beneficial to both performance and sound which is why race cars uses equal length. The combo of our headers with Akrapovic is awesome sounding. 4 Point 0 runs the same.

I did, but not from stock. I bought my car with just Soul Cat Bypass pipes and it sounded AMAZING!... but I felt bad running without cats and my 2yo rides with me and I didn't want the bit of extra smell, so I hoped going to Sport Cats and Headers would give me the same sound a maybe a bit more oomph. Unfortunately I lost a lot of the turbo whine I had before and I didn't get much/any seat of the pants difference.

I think maybe if I was coming from stock I would have been more impressed but those damn bypass pipes tainted my perspective! I also never use had sport cats, so can't comment on that, perhaps the headers do add over just them.

I'm actually considering the Sharkwerks exhaust even though most say its a big no no and too loud.

Did you upgrade your air filter?

Not on a technical track. Quickness (i.e. torque) is what you want, more so than top-end power. It's also the great equalizer on canyon drives (i.e. street version of a technical track). You combine the preceding with a good driver, and all of a sudden you start to question why anyone spent the extra $50k+ for that GT3 that gets largely driven on the street.

3_PDLS

Still stock Mike.

lamacan

no. that's what an unskilled driver would say. a GT3 is very easy to keep in the correct power band on a technical track.

and no. a canyon drive is not the street version of a technical track. the challenge with a canyon is you don't have road to use. you're stuck inside the lane. which is simply a balance and grip proposition. a GT3 would do significantly better due to more downforce keeping you balanced within the confines of the lap markings, as well as far more mechanical grip.

but you are correct in your last statement. if you are driving a GT3 largely on the street, you don't need to spend the extra money.

GT3 Nut

Dude, you need to lighten up and get off your high horse. Almost every post you have made on this thread is obnoxious and comes across as a know it all. Very tiring. Maybe you are so good and are far above everyone here as your posts would seem to indicate. But posting as you have on this thread will get you no praise. If you need validation, try racing...

lamacan

no high horse. i don't need validation. thats exactly my point. no need to validate the T against anything else. they are different cars.

there's a seeming desire in here to create some false equivalency between the T and objectively better cars which is stupid. I have a T. I love my T. I love it for what it is.

no sense in anyone trying to make it something it isn't.

GT3 Nut

Fair enough. I agree. Its a great car!
Good day, sir.

Hey guys, my T has the 18 way's with backseat. If I wanted to swap in a pair of the 991 GT3 seats, are these a direct plug and play fit? I know you could only order them with the rear seat delete, but curious is they will still work with the backseat and if it’s just a lack of entry or access to the backseat concern since they don’t recline forward? Will I have any issues using these as is with the backseat? How hard are they to swap back and forth if desired? It would be nice to have the buckets for track or weekend drives and then be able to swap back to 18 ways if desired.
