Hello Pascal,
You are more then welcome here.
We have very nice restaurants, shops and the Bosphorus... too much too see here, i'm sure your wife will love it too.
Regarding the intercoolers, we have tested every brand here, the best solution is water/meth injection.
It will cool down intake temp and it will boost your octane level.
We have installed more than 18 kits here, most of them were Porsche's.
Its really the way to go.
There is also one more trick that you can do.
We have produced bigger air ducts for the intercoolers.
They are like the GT2RS but wider to get more air. You can see them in the pictures below.

Wow that air duct inlet is huge!

what is the cost of the bigger air ducts do you have them?

Rebuilt engine with cams rods, etc etc with large gt2 VTgs and expansion intake (the one that none except my tuner likes!) making 740hp /950nm. Logging at 23 ambient around 52 max IATs (probably lower than 50 without an air leak i had). At 10 ambient logging around 37. All measurements to 300kms per hour with gt2 rs coolers. Have a simple water spray system for the ics, but not sure how much this contributes. I think the expansion intake is the trick with VTgs for up to my power level. But none seems to want to believe this.
100-200 in 5sec, 100-300 16.8 with passenger. All ecu safeties are on. Pump fuel 100 oct but really bad quality in Greece these days..
Have you tested those inlets you posted above Emre? Do they make a measurable difference?

I'm planning to test them on the same car, same day and same road.
What boost are you running with your current setup?
You are lucky to have 100oct fuel, we only have ''97'' here which is actually like the 95.

Thank you for your kind words.
We have them in stock, i'm just waiting confirmation from DHL
Cheers,

I talked with the guy responsible for aerodynamic at Manthey, he told me that they tried to catch more air with the modified fender intake but no success, of course they measured kilograms of air passing the core every time with modified air ducts.
but maybe you did something different
Emre, hope I will hear truth about the coolers finally from you

hum, hmm....
after analysis of a several logs from several tuned TTs and GT2s my synthesis is:
-There is no one air/air intercooler direct bolt on able to cool with real efficiency a tuned 997TT at high speeds. (>270kph)
Perhap's unproper airflow in the fenders more than the quality of the parts, but even very expensive Euro parts do not hold the IAT cool by 15°C AT...
-the best logs I received came from 2 cars fitted with GT2 expansion intake.
Most of the tuners (US and Euro) consider this intake as restrictive >650hp.
The 2 cars are fitted with different Ics and show correct logs.
The Ics are 997.2 s for one and TPCs the second.
So, perhap's the GT2 intake is a key for lower IAT, but some great tuners claim not...
My choice for now is keeping my 997.2 ics and using an external water injection.
I found an Aquamist system (from a toasted engine!) I will use to mist water in my Ics, seems to me the safest and easiest solution for now...

nothing can beat a good-tuned water injection setup in terms of cooling.. It does not only cool down your intake temperatures, it also cools down EGT's. Most tuners aftermarket IC will work well with your setup as long as you use water injection. Good call by sticking .2 I/C's and water injection.

Ah?
I was wondering where it was, so Ok, different intake would be responsible only if we could notice lower IAT with the sensors behind it...
So 997.2s and TPCs are the most efficient parts which I had logs.

Pascal, my logged performance data indicate that 740hp is indeed possible with gt2 intake. Need to run lean and with high ignition angle (that means good fuel) but it is certainly possible. Temperatures in the chamber are reduced around 10-15 degrees according to Porsche and this is where the power is coming from. IATs are lower as a direct or indirect part of all the above, not sure which one.
Otherwise you need different turbos or water injection etc. or maybe secans (still have not seen any logs though from 997tt).
