Brother, why all the angst and anger?? You don't seem to share your own philosophy. I'm fine with 991.2's or whatever. I told the .1 guys the same thing about the ECU tunes. I don't discriminate.
Anyway, thanks for following my work. Its quite flattering

You mention a hardware change is needed. Well, Porsche is providing you that hardware change. That is what the larger turbos are.
The hardware is capable of much more than 30 hp. As is the factory Carrera and Carrera S turbo hardware.
That is why I shared the compressor/turbine wheel sizes with you.
I can't give you a video of a GTS beating a 911 Turbo as I'm not in charge of what GTS owners do with their cars and I am also unaware of any GTS tune being out already.
However, you have a timeslip of a C4S with a tune on 21's running 11.1.
More data, videos, etc., will come out. I'll provide a video of my car for you as soon as I get a tune. I'll make it versus a 911.1 Carrera S just for you.

Hey I'm with you on the hardware. Thanks for the data on the .2's.
Look at .2 Turbo S >> to the new GT2 RS. Crazy what they're pushing with what seems to be same basic engine. Amazing cars and that's cool. Me, I'd take a .2 GT3 or .1/next .2 GT3 RS. Just my preference as you have yours. Why Porsche makes a zillion 911 variants which is the real story here. Who the hell has been able to pull that off with a single model?? Nobody.
Nice chat and have a good night.

We can only dream. The .2 S is priced out of sight for us working stiffs and found the base at least as powerful as the .1 S. Having a hell of a time trying to use all the hp my base .2 C2 puts out in lower CT.

It's not about personal preference here. I'm talking about the power kit and tuning. That has to deal with turbochargers.

Brother there is no angst and anger. I will say you are the master of deflection! Don't worry though - in a few months there will be a lot of .1's hot for sale.

I sure as hell hope so!!
They are at their lowest inventory levels EVER and have actually increased in price this past year!! I'm having a hard time doing my hobby. More cars for sale would be a blessing. Anything you can do to help would be appreciated. Not sure your plan, but fill me in! I'll assist you

I don't like alcantara and blacked out wheels and the blackeyes around the LED headlights and the lower spoiler on the GTS so I "settled" for a C4S, so to speak, but I have all the perf/handling options you get on the GTS except for the bigger turbos. I couldn't bring myself to click the powerkit button for $12K (although it includes more than just the bigger turbos for that price). Now I get to revisit this whole decision tree all over again?
I am quite seriously thinking about this. Gonna call my local dealership and see if they are up for it.

Notice what 911 the people who think this isn't a bargain have...
What really cracks me up are the guys saying 'only' 30 hp. Do they not realize you can throw a tune on top? It's a turbo upgrade with the factory's blessing that with a tune should put the car ahead of a 991.1 Turbo. You're buying potentially 100+ hp not 30.
Is it a value now?

Maybe you are new to tuning turbo motors or to the 9A2 engine? I mean the only thing funny there is your lack of platform knowledge.
Not to worry, I'll tutor you. Here's specs taken from this article: http://www.****************/content.p...ocharger-sizes
9A2 3.0 991.2 Carrera
Horsepower: 370
Torque: 332 lb-ft
Boost Pressure: 13.1 psi
Bore x Stroke: 91mm x 76.4mm
Redline: 7500 rpm
Compression Ratio: 10.0:1
Intercooler: Air to Air
Turbos: 49mm compressor/45mm turbine
9A2 3.0 991.2 Carrera S
Horsepower: 420
Torque: 369 lb-ft
Boost Pressure: 16.0 psi
Bore x Stroke: 91mm x 76.4mm
Redline: 7500 rpm
Compression Ratio: 10.0:1
Intercooler: Air to Air
Turbos: 51mm compressor/45mm turbine
9A2 3.0 991.2 Carrera GTS
Horsepower: 450
Torque: 405 lb-ft
Boost Pressure: 18.0 psi
Bore x Stroke: 91mm x 76.4mm
Redline: 7500 rpm
Compression Ratio: 10.0:1
Intercooler: Air to Air
Turbos: 55mm compressor/48mm turbine
Now, look at a tuned graph for the 991.2 Carrera from GIAC:
![](http://www.germanboost.com/images/imported/2017/05/10mph12-1.jpg)
Notice 100 lb-ft of torque AT THE WHEELS gained at 3000 rpm. This is on a more conservative Mustang dyno which I myself have also dyno'd my 991.2 on.
Peak power goes up by 54 as the curve levels off toward redline. That is roughly 75 crank horsepower or so depending on what drivetrain loss figures you ascribe to. Yet you just stated that isn't possible? Well, it's staring you in the face.
So, you think the GTS with its larger wheels that will hold the torque curve further to right will not show larger horsepower power gains with a tune?
I'd love to hear why.
You're paying for a factory backed and tested turbo upgrade with the potential of offering over 100 horsepower over the Carrera S 420 as I already stated. Maybe now you'll understand.

Every ECU Tuner has graphs to sell their product. I'd like to see it out on a straight line in real world.
All I ever see are graphs and never any real world proof. No videos ever. Show me a video of a .2 C2S or GTS beating a .1 Turbo S
No hardware changes and 70HP+?? Ain't buying it.
Anyway, have fun![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)

I can lead you to the water but I can't force you to drink it.
The amount of turbo or forced induction vehicles gaining 70+ hp tune only these days is too long to list. I can see why this is shocking for 991.1 owners.
Somewhat disappointing the level of technical discourse among Porsche owners isn't higher caliber.

But the problem with the aftermarket tunes (like GIAC et al.) is the warranty.
X51 maintains the OEM warranty. That, to me, is worth the price admission alone, even if I come up some 80 hp short versus some aftermarket shop.

I'm likely in for the kit - great result, lots of head room and my car was pre - prepped e.g. SC and PSE. Good to go. Great gains across the whole curve without the very high losses associated with high revving NA engines.
