Ok, so i went n read some more, chatted to some people and worked out what i had wrong with the other condenser i use and im happy to take my Spanking.

Please sir may i have another lols

So in my reading a couple of nuggets that popped out for me were...

No point having a radiator larger than the actual open area of your grill minus any mesh and so forth, seems like common sense and would point to where a smaller thicker radiator could work better than a wider 2 core one depending on the car.

One source stated that the ideal flow speed through a radiator tube is 6-7 feet per second with the errosion factor starting at 10fps - thoughts, comments, is it worth the math to work that out?

It would seem to me that an external electric pump like the Davies Craig ewp 40gpm with a diy pwm control for it and thermo fans would be a good street set up that would be traffic jam indifferent? No doubt insufficient for a serious engine with sustained rpm, thoughts?
