I keep following developments and when I see actual figures I begin to wonder if diminishing returns point was passed some time ago? All the energy and time and $$$$ spent on Cascade SS and super small tube sizes.... is the improvement substantial enough to justyfi it? Don't get me wrong here, I don't want to be a party pooper but I like to ask such questions
On the side note, I think it was Les who posted link to a page with some calculator dor convective heat transfer coeeficient for a water jet. It remided me of another thread about Cathar's blocks here on procooling. I reminded me of this thread bacause drawing showed on this calculator page neatly supported my suggestion for improvemnt of jet type block - designing out stagnation zones while at the same time increasing surface area and jet pressure by decreasing&modelling cross sectional water jet area.
This would allow for bigger diameter jets, fewr ot them, cheaper (shorter) CNC and higher stress durability.
Earlier on Cathar was quoted writing about the need for suoer clean system... micro water filters.... I think BillA is right by saying this is not for the masses
