Now that is a great technical question! I would think the pressure would drop dramatically as it has a larger surface area to push a huge volume of mass through. Then again we don't know what the boost/pressure capacity is either.
A lot of engineering thats for sure!
I like the question very poignant... good stuff to know.

This issue is especially important on a non-positive displacment induction package where you are actually loosing cfm going into the motor whereas with a positive displacment SC, the blower essentially pumps the same amount of air per revolution (in theory).

If one were to compare 2 cores of equal cooling capacity, a core that is wider and longer with a lower profile will have a lower pressure drop than the core with a smaller cross sectional area that is taller. There are obviously other things that come into play such as the number of fins per inch, fin thickness, fin profile, # of tubes, and size of tubes.

Exactly, his unit came to my mind as well when thinking about the pressure drop in relation to the cooling capacity and restrictiveness of the core. Tom makes a nice unit.
