Stephen,

What Porsche did was to incorporate longer fins and more fins (closer together). I am not sure why they put the fins closer together. I have an intercooler approaching 80% efficiency (without CO2). There is no need for bigger tubes. There is a need for thicker core with fewer fins (more space for air to flow through fins)

Maybe what Porsche is doing is a compromise between street and race. My race intercoolers are less efficient than stock when I am poking around town. However, when the air starts to move they are a lot more efficient than stock or GT2 intercoolers. We were able to mitigate some of the low flow loss by using a product called Radiator Relief.

 

So back to the topic....Anyone upgraded to aftermarket intercoolers?? If so which ones?? Any recommmendations?

 

If they weren't such a PIA you could dyno with a stock vs X50 set eh? My guess is if you haven't noticed any temp changes then I don't know where that 5-10% is going?

 

I installed custom ones made by S Car Go Racing.

 

buy a regular tt,then modify the car..i think for 17,000.00usd for the x50 is a waste!my opinion.....i was going to buy one,then i knew i was modding my car so i bought a reg tt!!!just my opinion

 

After reading and posting on this board, I think we've all developed a sickness for more power/mods. I dont think there is one 996TT owner on this board without any performance mods (or at least... thinking about getting it done).

I thought I was going to be perfectly content with the power when I bought my car...however after 10K miles (in 6 months), im seriously contemplating larger turbos and ecu tuning (again).

Bottom line...if you plan to participate on this board...get the standard TT and you'll soon realize why....MODS and MORE MODS!!!

 

The problem is the days of cams and a total engine design is over.Technology has allowed us the same type of gains on the newer chassis then the older ones. Sharing the sickness of HP is too easy. My motto is still "will work for HP"

 

I caught the same disease. I thought I could stop at the level 1 ECU. Then it was an exhaust. Then larger turbos, intercoolers, headers, and more tuning. Next, probably PSS9s. Maybe wheels.

So... I think your recommendation makes sense. Although, I'd recommend buying a slightly used standard TT to get a car that is (1) already broken in and (2) has already taken the large depreciation hit.
