997TT intercoolers same as 996GT2?

[contigo]

Does any one know if the intercoolers on the new 997TT are the same as the 996GT2? Or what are the differences if any?

[Loren]

997TT uses 997 part numbers.

[contigo]

So are they the same and they change refs nos?

[Loren]

I serious doubt Porsche would stock the same part under 2 different numbers - not very cost effective.

[contigo]

All I have heard it is the same cores but no sure if the same cores as the GT2 996 and they make some changes probably on the ends, but heard also the hoses and everything on the 996TT will fit, want to know if they are an up grade or maybe just the same stuff

[Loren]

Perhaps you can find a dealer that will let you look at one of each?

[contigo]

Not here, the dealer here doesnt stock any parts here just filters, very bad service in our country from the PORSCHE REPRESENTATIVE

[Loren]

The 996TT/GT2 parts are cheaper (here in the US) than the 997TT parts - so I would use the 996 GT2 parts.

[contigo]

Seems we are alone on this one and neither knows the answer, there are some 997TT new ones on e bay for $200 each

[dixie]

Yes they will fit,I have them installed on my 996TT ,but only 3 of the 4 mountings will fit...

[contigo]

Great!!! for that fitting that didnt fit did you just change the clamp? Any difference you can notice when you changed them? Earlier boost, more boost, etc?

[contigo]

Great!!! for that mounting what do you do? Any difference you can notice when you changed them? Earlier boost, more boost, etc?

Unless i'm missing something here, how is an intercooler going to give your more boost or spool up faster?? They are just what it says on the tin.......... a cooler. So an upgrade only will make the oil cooling more efficient etc, not improve your performance? If you run bigger turbo's you need better intercoolers to keep the oil temp around the turbo's within limits so you 'maintain' optimum performance and dont damage anything. But intercoolers alone wont give you more BHP??

why do you think intercoolers would give you earlier boost?

if that's what you want you should be looking at ecu flash with hybrid turbos

upgraded intercoolers only help you on a hot day / during track session, if you have upgraded turbos

[jjcodex75]

Not necessarily. IF the new intercoolers flow better, then they will improve volumetric efficiency, which may yield a slight improvement in power.

AIR INTERCOOLERS, WHO IS TALKING ABOUT OIL INTERCOOLERS?????......

There are air intakes and intercoolers...different animals. The ICs cool the charged air, lower the temp. the denser the air and hence more power can be made through more efficient combustion. The stock ICs on a turbo are fine unless you:

1. track

2. drive in extremely hot ambient temps.

3. have high hp mods.

The turbo ICs are essentially heat exchangers Air to liquid in water cooled Porsches. Intakes bring cold air into the system.

I believe the ICs on a GT2 are more capable than a TT (996 or 997).
