Intercooler: horizontal or vertical core

[gui67]

Did someone already made a comparison between intercoolers with horizontal core ( smaller sectional area and longer exchanger) vs vertical core (short exchanger but with bigger sectional area)
here are some picture to help you understand what I mean:
vertical:

horizontal:


for the same frontal area, the vertical would be better because it causes less pressure losses (lower air speed in the channels and less length.

But in the real life, on my 67 camaro, I only have limited space and need to put one pipe on the side to go to the upper tank for a vertical core, which means less frontal area.
I made some calculations using the space I have on my car:

the horizontal core would have 3 times more pressure losses then the vertical one, but also 48% more frontal area.



here are some details about the data (for 6000RPM, 6.3l, 85%volumetric efficiency):
horizontal Vertical
air speed: 15.9m/s 12.5m/s
core length: 470mm 250mm
frontal area: 0.21m2 0.14m2

Is there a rule for maximum air speed in the core in order to dimension it?
Did someone already made some comparison of 2 solutions in the same car and saw a difference?
The pressure drop from horizontal core could be overcome with more pressure from turbocharger, but that again creates more heat...

What is a common pressure loss in intercoolers, maybe it is so small that the 3 factor in this case would change nothing
