Now that said, they are correct that moving the water too fast can hurt since you’re not giving the water adequate dwell time on the heat exchangers for the heat to actually transfer. The example I give my guys is sort of like a train station…if the train is flying by the loading dock, no one is getting on or off the train haha!

I’m going to say it yet again: capacity does NOTHING for cooling. It’s a band aid for inadequate heat exchanger units and/or improper flow. Period. Now if you know you’re not upgrading your blower bricks or heat exchanger, and more water capacity can help that, then by all means go for it. Interchiller is in the same boat…it won’t cool fast enough at WOT so you need some capacity, so I get it. But E85 is superior to a Interchiller and renders it unnecessary since alcohol needs heat to properly vaporize.

Back to capacity: I run zero capacity in my system and enjoy IATs that drop as the run goes on…because I have good heat exchangers and good flow. As I continue to turn the power up, I will probably make more improvements on that front using Gabe’s stuff. If I reach a point in power output where larger heat heat exchangers don’t keep up, then I’ll begrudgingly add capacity. But that’s extra weight so it’s a worst case scenario so I’ll avoid that as long as possible.
Thanks for jumping in Josh, this is a great topic! I was under the impression that laminar flow actually helped transfer heat between the layers of flow from the slowest moving nearest the heat source to the center of flow which is the fastest... similar to blood flow in the body.
