Hi Willie

the crux of the issue is data
w/o data its all conjecture and degrades immediately to debating opinions
and the data is so costly that none who have such will release it

worth observing is that the designer does not have to be the mfgr, the QP rads are a case in point
and, like Willie, there is another big step up ahead

if you users would like to contribute, state what you would like to see in a new rad
- then watch the scramble to make the product, IF someone thinks there is a real market
(and not 6 extremists hyperventilating with each other, I'm reminded of the 3 fan rads)

there will be a significant amt of comparative data released shortly, by the same source as ever
performance data, not radiator 'design' data; good for inferences however
