Track cooling recommendations - ZR-1 Net Registry Forums

I am currently refreshing my '90 with a full under plenum service including injectors and coils, I have also deleted the secondary system and removed the associated hardware and vacuum lines.

My plans with the car are to be a street/autocross car with some HPDE mixed in. I have a new 2 inch DeWitt radiator as well as one of Pete's underdrive water pump pulleys. I know the bypass system posses a problem with sustained time past approximately 6k rpm. I have searched and found mixed answers in posts about other options for helping keep the car cool for the occasional 20 minute HPDE sessions. Any help or links would be appreciated.
