My air to water experience is fairly limited to the DSM platform, I have had numerous friends run it successfully. Their biggest issues typically related to keeping the coolant side sealed as the length and complexity of the lines were prone to leakage. They simply work when done right.

Your charge cooler looks to be at twice the size of what my DSM friends ran, so that tracks given the nearly 3x displacement increase and higher boost pressures being seen.

Most aftermarket charge coolers I've seen mounted to the side however, not directly above the engine. I assume that diesel will throw off a good amount of heat, especially with the turbos inches away, but you do appear to be liberally applying insulation that should help offset.

Given factory supercharged applications like the Hellcat and ZR1 included air to water intercoolers (charge coolers) are integral into the supercharger, even closer to the heat of the engine block, I'm sure you wouldn't be the first engineer combatting ambient temperature impacts on the charge cooler design.

I'm very interested to see how it works out, how close you get to target temps. Will you have probe(s) to monitor while driving?
