I'm afraid the 25k € stage IV is with the "special intercoolers" and not wit the "Secan intercoolers" according to CG website.

It said special IC before too, on the IC picīs it is Secan with 15 cooling channels and it says RS Tuning on them. RS said to my tuner that the new cheaper ones (second picture) doesnīt work with stage 4 well, tomorrow I should know...

These ICīs are from Cargraphic.de, Secan and CG new special IC that lookīs the same as FVD has.

http://www.cargraphic.de/index.php?/...,3811/&start=6
I think CG use wrong picture (Secan) instead of the new special ICīs on their homepage.

9ff ICīs cost 3950€ excl tax and they use them from 600PS to 750PS after that they use water cooled ICīs, thatīs all I know.

Cargraphic used wrong price (25k €) for stage 4 and has now change it back to 35k € + tax on their homepage. I got an offer I canīt refuse for the new ICīs made by NASA and according to CG they add 15-20PS to Stage 3.

You can compare your car with TB`s RS 660HP GT2, I doubt your advantage of 40HP will matter there, he is on rennlist forum (TB993TT).

I think his car is faster or at least not slower than this kit for 997 Turbo:

tuner: Cargraphic/RS Tuning
kit name: Stage 3 + Carrillo
Turbo: VTG
ECU: standard Motronic
Intercoolers: Secan
exhaust: Cargraphic
air intake: Cargraphic carbon
extra parts: CG headers, 100 cell race HJS cats
dyno resault: engine dyno: 624PS, 900NM DIN
Max Power=..624PS- max torque=.662ft-lbs with 100RON Shell V Power PUMP fuel at.DIN....bar -Temp=.DIN....
Max Power=.N/A.- max torque=..N/A..ft-lbs with RACE fuel at.....bar -Temp=.....
0-60mph: est.2.9s...sec 0-100kph: 3.0s
0-100mph:est.6.8s...sec 0-200kph: 9.1s
60-130mph:est.7s...sec 0-300kph: 23.8s
1/4 mile:....sec @ .... mph
standing mile:est .30s..sec.190....mph
transmission: 6spd 890NM Sachs clutch
Man my 997tt tip is faster than this GT2

Where did you read that, don't think I ever said that ?

They are broadly similar, on a Schmirler tuned engine they keep within about 20-25DegC of ambient.... on other "tunes" your results may vary

I think I am fairly safe in saying to expect some RS Tuning engines to be sporting a set in the near future "

Sorry if I misunderstood you, but it gave me the impression that the Secan was still slightly better?
Yes, see what you mean...

When they did the test it was with that tuning box "tune" the IATs were crazy as the programming was overworking the VTGs big time, they thought my ICs were not good but then swapped to Secan and the IATs were virtually identical, I think he said they were maybe 2 deg C better with the Secan but that was at the ~75DegC level so barely relevant. I suspect the Secans would always HAVE to be a little better

On the engine dyno the average IATs used (during tuning) via the water cooled IC were 36DegC so he definately knew what he was working with....

Those numbers are the same as a bone stock 2010 911 turbo...

Not to forget, a 2010 Turbo with PDK and launch aid. Those two features alone are probaly worth about .3-.4 seconds.

Not to mention the RS Tuning GT2 achieves 300 km/h 15-17 seconds faster.
