Vertical vs. Horizontal Intercoolers
Your thoughts? Anyone run one on their SE-R?

This would probably be where any added cooling would come from, because the air would likely be moving at a lower velocity with more time to cool with all the extra rows.

So most of us have seen the APS site touting the benefits of a vertical flow IC.

I always thought ya ya whatever.
So lets see its a 9x25x3.5" = 787.5 in^3 compared to a standard 12x24x3 = 864 in^3 horizontal FMIC found on many of the turbo kits
Similar cubic area so cooling should be the same.
But looking at Bell's website made me wonder..

So this time the comparison is between CFMs
Vert: 1607
Hori: 484
Interesting. almost 4x the CFMs for the same area. To match that same CFM on a horizontal you would need a 40x24x3" core Even if you want to a 3.5" like i think the GTM/Greddy kit is, you'd need a 34x24x3.5" for the same CFM
so I guess, do CFMs contribute as much to cooling as does physical size? And all else equal, would you want to gain that extra volume by adding thickness or frontal area (more space limited in that option)
