Sorry to bump an older thread. For your setup, do you know what kind of flow you're getting through the entire system? I'm about to embark on some similar mods and will be curious what you achieved. Your setup looks awesome and love the attention to detail about avoiding sharp bends. Thinking about the same thing on my side. Plenty to ponder.Yeah it's running and seems to be performing as expected. For my purposes it's what I need for 20 - 30 minute road course sessions with sustained high RPMs and repeated demands for WOT. Lots of air flow thru a huge H/E (no fans, they restrict air at these speeds) and lots of coolant flow thru the system to pull heat quickly. A trunk tank would just add unnecessary weight, complexity, make the pump work harder, and ice won't last long enough. If you're drag racing and run with ice to get IATs below ambient that's an entirely different strategy.
