CSF makes a nice product.

 

As I said you need flow, yes when the car is moving you will see some. At idle kinda doubt it! Water pump is pumping less and the air movement is limited.

 

you are forgetting both heat reserve/capacity of the radiators, as well as fan forced airflow they see at a hot idle.
Am not sure what the OE-spec W.P. flows L/hr. but it works....
Results are results; mine runs cooler in the operating parameters it is subjected to. I had previously thought of adding the additional TT rad fan to my GT2, but no longer need to.

 

I am putting on a set soon too.

 

Fan forced airflow is not normally in high speed, it goes to high speed if the AC is on or the coolant temp reaches a threshold. I agree you should see better cooling once the car is moving and engine rpm goes up to force more flow. I bet if you idle your car in hot weather for a period of time after a full warm up, you may see a slight difference but not much. These radiators excel when you have good healthy air flow and engine speed driving coolant flow. Once the radiators are heat soaked, if airflow is not up, they will remain at that temp. Hence the reason I said I wish there were higher flow water pumps available, then you max the entire system. I am not bashing these radiators they are great and a wonderful alternative to Porsche OEM.

 

agree!

 

Had my set installed last week however the temperatures here in Vancouver BC arent even remotely hot for me to provide any feedback. lol. Will know better come summer once track season starts up again

Great, well made product based on first impressions though!

 

figured I'd update this...
I have the first set of CSF rads made for our cars, and now have just over 40,000km's on them, have been trouble-free and temps have been great, street and track.
Cheers,
