Is this IC coolant system tied into the engine coolant system via overflow tank or was that bypassed? Do you have a DIY parts list your might provide? If isolated, is this the same 50/50 antifreeze mix. I was toying with the idea of using a different type of actual heat transfer fluid other than gycol based that might give better heat dissipation. So much is written about the IC Pump and adding bigger HEs, but nobody is talking about the actual fluid in the tubes that is actually doing all the work. What's the total capacity of your system?
