Different power steering cooler kit

[Quicksilvers]

I currently have a fabbed up Mishimoto power steering cooler kit installed at the last track event my power steering system was taxed on the first lap as on inspection my power steering fluid was boiling. In the past I have compared the Mishimoto power steering cooler to other aftermarket power steering coolers and the Mishimoto power steering cooler is smaller. I need to install a different aftermarket power steering cooler what power steering cooler kits do you all recommend? I also need to completely flush and refill my power steering fluid what brands of power steering fluid do you all prefer to use for track duty that has a higher boiling rate?
