PDK dilemma - turbo = major overheating?

So I'm looking at picking up a 2nd gen PDK...

I know some people with 09 and '10 PDKs have had overheating issues on the track, which I assume is why Porsche added the 3rd radiator in '11.

The problem is that I'd eventually like to add an intercooled TPC turbo kit when one is available for the 2nd gen ...

There's no room to add yet another radiator up front for the intercooler in an '11, so that means I should be looking at 09s and 10s.

But if stock 09s and 10s already have overheating problems, I can only assume that significantly boosting the output with a turbo kit will only make the problem even worse.

I'm sure that adding a deep sump with a few extra quarts of oil along with an oil cooler would help, but I doubt it would help enough.

Anyone have any thoughts on this? Surely I'm not the only one who is looking forward to a boosted 2nd gen PDK CS...

I'm not a tech, but trying to clear few things.
1 When you are saying gen 2 PDK overheating, did u mean PKD tranny oil or engine oil overheating, or both?
2 I believe the 3rd radiator that TPC using is the oem one, they just add another air to liquid engine oil cooler underneath.
3 Either high boost or low boost, it would not effect PDK. I believe Porsche running tranny and engine oil coolers separately.

The people I've talked to say their PDK cars just overheat when pushed hard on the track. The water temp ranges anywhere from above normal to almost maxed out on the temp gauge to the point where you have to come in depending on ambient temp and how you're driving.

My point about the radiator is that 2011 PDKs already have a 3rd radiator up front - I assume to address the overheating issue. So it's gonna be pretty much impossible to add an intercooled turbo system to an '11 because there's nowhere to put the radiator for the intercooler.

That leaves having to use an 09 or '10 car to start with, since they don't have the 3rd radiator from the factory, which allows you the room to add another radiator up front for the intercooler.

But that leads back to the original problem ... if the 09s and '10s overheat on the track stock, I can only imagine that adding a turbo will only make it worse if anything. Either way there is no room to add an additional radiator to help prevent the overheating if you're running an intercooled turbo kit because there's nowhere to add what would then be a 4th radiator.
