Might get more feedback in the TT forum.

I'll give it a try.

Thank you!

I've heard from a couple of sources that there actually is a shortage of new turbos or maybe TT-S in the US. Amazing considering the price point. One would think Porsche would make sure these cars are readily available!

I could be all wet, but isn't the Turbo kind of a rare breed? I've seen all kinds of Turbo S cars, but I can't say with any assurance I've ever seen a Turbo in the wild.

When I was looking for a Turbo S, no dealer could get me one. All of them could get me a regular Turbo, and I was offered discounts. Turbo S allocations are very few and far between, but it seems like it is much easier to get a non S.

2018 911 allocations of all flavors are seemingly hard to come by right now, with the TTS very sparse these days. My dealership connection told me it was due to Porsche overproducing them in 17. They weren't happy with the discounting going on to get the inventory moved, so they backed production down a good bit. What I was told anyway.

We have a few allocations available through my store, and we just got one on the ground.

I've been a Porsche aficionado since when I got my 928 S4 back in 1987. But I really don't care for their pricing policy.
It seems Porsche's marketing philosophy is that if 10 people want to buy a Porsche... then only build 8.
I guess they can control the pricing that way.
But no, that can't be possible.

I think that's true, and due in part to the clever way Porsche does their pricing. If you added up all the things optional on a Turbo but standard on a Turbo S, you get really close in price, and still would be short some horsepower. The key to getting a Turbo is to exercise restraint in filling out the options list, which then nets you not exactly a bargain, but a much better value proposition. I'm told (but don't really know for sure) that the difference in power between the 991.1 Turbo and Turbo S is only tuning or mainly tuning, so you can get Turbo S power on Turbo with only a Cobb tune or something similar. That is not the case with the 991.2, where you can't do that with just a tune. Or so I'm told.

Anyway back to topic, it's seems unlikely that you can get a discount on a Turbo S, though that should not discourage you from trying. As others noted, Porsche keeps allocations at just under the expected demand, so that dealers can maintain profit margins.

While the turbochargers are now different for the 991.2 TT and TTS, the difference is quite minor and appears to be as much a matter of differentiation as performance. The compressor size difference is 2mm - 56mm vs 58 mm. While tuning them is not settled yet, the claimed outputs for reflashed cars so far have been identical for both versions - here's the first tuner I found with a tune for both variants:

https://www.vividracing.com/tuned-ec...151880265.html

The TTS is programmed to build an extra 0.2 bar of boost, TT->1.0 bar and TTS->1.2 bar, and both cars additionally have +0.15 bar of overboost. Since atmospheric pressure is about 1.0 bar, the TT manifold pressure would peak at 2.15 bar vs. 2.35 bar for the TTS. The pressure ratio is 2.35bar/2.15bar=1.093, but the rated engine power ratio is 580hp/540hp=1.074. So the TTS uses 9% greater manifold pressure to make 7% more rated power. While the turbocharger has been tweaked, it looks to me like the ECU programming is where the S finds nearly all of the extra 40hp.

All that said, if you want the S, GET THE S! This is a purely discretionary purchase. Get exactly what you want or compromise slightly and get it CPO'd to save a large pile of money. No sense going 90% of the way.

ace37; I can't say between 991.2 TT and TTS differences, but at least two tuners (one in particular) are pulling out well over 600hp *to the wheels* with the 991.2. According to member testing, the 991.2 is good for more than a second better 60-130mph roll-on testing from 991.1 to 991.2. My understanding is that the 991.1 TTS has the same turbos as the 991.1/991.2 TT. However, I may not be correct on that.

What I do know is that my 991.2 car ran 10.68@135.99 with wheelspin at full weight and OEM tires. No performance upgrades whatsoever. I calculated DA at around 2200 (I am not expert at this, mind).

Holy smokes... man these cars are rockets... that's a lot of improvement for so little time on the market. The turbocharger info came from an issue of Excellence when the 991.2 TT/TTS was announced - I tried to find it quickly to link it but I didn't succeed. I'd like to learn about what hardware changes were used in the GT2RS and TTS exclusive and if the GT2RS turbos will be purchasable without either an RS VIN or a 500+% markup. In any case it seems clear there is a lot of untapped potential built into the 991 TT and TTS.

At this point my paltry 540 hp is serving me just fine... I'm at 4400' altitude in high desert, so 7000' density altitude in the summers is common. Turbochargers have a big benefit here with altitude compensation so it's quite rare to come across anything that is even close in real world performance. NA and belt driven SC engines leave a fair bit of horsepower down at the base of the mountain.

Anyway, sorry for the OT. Get the car you want - you can't go wrong, and if you can't tell, we love ours!

991.1 TT, 991.1 TTS and 991.2 TT have the same sized turbo, but 991.2 TTS has a 2mm larger turbo. Not a big difference, but in 991.2 turbo is the bottleneck (intercoolers too, but that's easily fixable), so increase in turbo size pay good dividends. Of course, either of the cars has too much power already. 991.2 also has upgraded fuel pumps and injectors and optimized internal airflow.

based from our vbox tests here in the Philippines between a mk.1 TS and a mk.2 TS, the power difference is quite big. around 1sec 60-130mph. the bigger turbo just pulls much stronger on top despite being only 2mm bigger as you say.
