R32 GTR Radiators.

[mazgtr]

Im looking at entering a few track days soon, and have heard from a few workshops and a couple of owners, conflicting comments concerning the ability of the stock R32 GTR Radiator to prevent the car from overheating when punted around a race track. I was just wondering if anyone here has any advice or an opinion on the subject, wether you do track days with the stock radiator without any problems, or if you've been forced to fit an aftermarket replacement Radiator.

My R32 GTR car has 2 x HKS 2540's and makes 330KW @ the wheels.

Thanks.
