Hey folks,
I'm thinking about using a Fedco 2-775 (for a 93-95 Plymouth, Voyager - 7.375"x6.25"x1.25").
$40 at Parts America $30 at Rock Auto .
I watercool primarily for silence and have had some problems getting air through a 2" heater core with an axial fan that's undervolted to the point of being inaudible (Panaflo L1A at 5V for instance).
Given that frontal area is the most important thing (see Cathar's explanation of why an in-air-series radiator adds little cooling in
this thread) I may be giving up only a little in potential cooling, to be gained back by being able to move more air at the same sound level.
I've sent emails to both Rock and PartsAmer. asking what the cores are made of - but they may or may not know and I would guess that someone here who has used one
would know.
I'm also curious about resistance to water flow, but, as I'm building systems that only flow somewhere between .5 and 1GPH and resistance is proportional to velocity, water resistance isn't as important as air resistance...
Thanks!
Bob
