In addition, the horizontal i/c is requiring air to go through a smaller area that is over twice as long as the vertical flow's. (24" length vs 10" length).
Now there are many other factors, such as tube size within the core, fin density, etc.

I run 5.21-5.28 at 138mph in the 1/8th at 3450 raceweight and 20lbs of boost.

It works.

At the top of the track, on a hotlap pass, IATs pre-intercooler were 220*F, post-intercooler were 100*, ambient was around 85*. Max pressure drop was 0.5 psi.
