Hopefully somebody can help me out with this. What is the average static pressure (Pa) of a run of the mill heatercore? i.e when air is pushed through the fins, how much backpressure is generated. Just a rough estimate is fine. I hope I've got the terminology right

It varies with fin-density, thickness, and air flow; no simple numbers.

Bill Adams did some radiator tests that included static air pressure. I can never find anything on overclockers.com, but its there somewhere.

Thanks for the info I am just considering whether or not to shell out for a fatty radial blower or just stick with axial fans for my new project. The only limiting factor in the blower is that at higher back pressure the flowrate drops right down.

The size blower I'm thinking of getting should be able to cope with it though.

Opinions?

That should be more than enough. I thought about getting one with the square output side about the same size of the rad fins for an external box.

Yeah, this one fits over the heatercore I'm using pretty much dead on, that's why I want to use it. It's going on an external unit too, no way I'm having that thing hanging out the side of my box!

They cost some serious dollars though, but it will be pretty unique when I've finished it all up.
