I dug around for pressure drop info and block and pump curves and did some not-so-WAGing.
I found Cathar's flow estimates for the cascade in a 1/2" system with a pro-core: 1.15 gpm for eheim 1048 and 1.6 for mcp600.
His estimated pressure drop for the Cascade at 1gph of 1psi.
JoeC's measured pressure drop for the mcw50 of .26psi
Using that info, I'm guessing not more than 1C improvement with a stronger (greater max head but louder) mcp650, assuming that the caprice core has pressure drop similar to the procore. Is this reasonable?
The most significant weakness would therefore be the weak axial fans I'm using with such a thick core. If I could install a properly shrouded blower at the sound levels I want, it might help.
Does anyone see reason for me to reroute the tubing (from the most recent pic above) to pump-rad-cascade-gpu-res ?
