Can't quite fathom how the air flows throught them or how they could have enough capacity, but they sound like the go....
Has anyone priced them; I imagine they would be priced out of the backyarders pricerange? They may fit very well into the Ritchwood technologys supercharger manifold.
They need to be configured into a plenum close together to eachother and the walls of the plenum. The cooling media (water) flows through them and the air flows around and inbetween the fines on the outside of the units.
