Pressure drop is an almost impossible question to answer. Each application, each SC (turbo, screw, roots, centrifugal) will differ. With the massive amount of surface area, there is really very little pressure drop.

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.

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).

That's exactly why Tom Robinson's R-Tech Supercooler, designed specifically for centrifugal superchargers, was so effective. Very low restriction, minimal loss of boost.

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.

Looks like a copycat cooler to me.

LOL, thats pretty funny! Is that copying by making bigger core, rugged bar/plate design, offering aluminum and cupronickel, oversized water fittings???

Split housing. And why would you offer aluminum cores, they don't last.

I have seen Jason's coolers and they look like a work of art , also congrats on his results at LOTO
