I think part of the problem with rad Temps is where I was trying to measure from. I was taking the temp on the top tank/inlet, and again on the bottom tank and only had a 10 degree difference, which is consistent with the same measurement points i just took on my cold case radiator.
If comparing the temp at thermostat housing to bottom tank/outlet, we are getting the the ~30 degree drop on his radiator as well as mine.
I imagine the radiator itself is distributing the heat somewhat evenly (within the 10 degrees)across itself.
His radiator seems to be a newer aluminum with 2" core, and vertical flow, so I think it is "mostly" doing its job. My cold case is a cross flow, which I assume cools more efficiently then the vertical flow models?
