Are you doing this one as a 2-pass also? I think we talked about it but I don't remember.
No, I think it will be easier and more effective to just make it as a single pass. The larger the core is the longer the water will stay in the radiator so I am sure it will be fine.
If not I will charge the system with liquid notrogen.
