Anyone install this ??

My car has the 3rd radiator kit because it's equipped with the Powerkit. Now, my brother installed the corresponding version for his former 996 Carrera as a modification prior to bringing it to the track for the first time, as added precaution to keep temperatures in check while tracking. Overall, we think it was a worthwhile modification but don't have any quantifiable evidence of its benefits.

I put one in my 997.2. It's a worthwhile addition for anyone tracking a 997. Suncoast has a really good deal on the 997.1 kit.

I have this as well as it comes with the X51 powerkit.

good idea to aid in cooling. As others may have mentioned you can get them right now on suncoast website. Great idea.

Should have come standard from Porsche in my opinion

I just ordered one. Figured it can't hurt.

Actually it can hurt. Having the third radiator will slow down the engines warm up when you first start out. Unless you really have a heat problem I wouldn't go to a third radiator. Generally, one thinks that having a third radiator is a good idea, but you have to give it some real thought and it has to be based upon your local driving conditions.

Car does see track periodically in high temps.

I am careful to warm up before high revs are allowed. BTW, Suncoast has them on sale for $189 - for the 997.1.

How will a third radiator slow down engine warm-up? The thermostat for the coolant will behave the same way whether there is two radiators or three.

I think anyone living in a warm climate would benefit from the additional cooling.

My exact thoughts. the water pump will pump water around only the engine until it gets too hot and the thermostat opens to allow the water to flow through the radiators. One issue may be that the water that eventually comes back into the engine from the 3 radiators is too cold causing larger swings in the coolant temperature in the engine.

I know that the oil in the engine is normally cooled by the engine coolant. If I understand correctly the 911 has an additional oil/water heat exchanger. Is this for the engine oil and/or the gearbox?. How is this system connected to the engine coolant system? How independent are the two systems?

Unless it's electrical there isn't another water pump. Is there another thermostat for the oil? This would allow the water pump to pump water through the radiators when the oil temp gets too high even if the water temperature of the engine is okay and the coolant thermostat is closed? Or is it much simpler in that if the thermostat for the water opens then it's assumed the oil needs cooling as well and the water circulates around the entire system?

Damn it, they've increased the price now from $189 to $249

They really meant limited time

Suncoast has these again for $199. I just ordered one for my S.

wondering if it has all the pieces.

I installed the same kit front Suncoast last month. Very straightforward. I was concerned that the hoses might leak because there is a bit of play in how they fit but they held tight. I was not used to that type of clamp. Overall very impressed with the quality of parts and completeness of the kit considering the cost.
