Indeed wasz 'forum experts' are indeed limited in their resources and this should be borne in mind by those looking to follow their advice, always better to listen to or seek guidance from those who do know what they are talking about. In this case it would seem that following our 'forum experts' recommended mod number 2 actually makes matters worse.
Unfortunately, much like the scientific analogy made, knowledge is an evolutionary process.
Baz updated his new findings on this current thread, I did my limited (by measurement resources and sample engines) over two years ago in July 2011.
Now I am not attempting to compare myself with Newton, but we don't think he is an idiot because 300 years later Einstein updated the rules, and we certainly don't devalue his limited research.
At least I do my own research and any post to that affect has been with the genuine intent to help.
But I do genuinely believe (irrespective of the relative temperatures experienced at the entry and exit of the 3.4 M96), that the proportional cooling chamber design on the 3.4 M96 is the reason both my experiments and conclusions differ from the advice for the latter (poorer) uniform cooling design of the 3.6 M96 and 3.8 M97.
And to be fair, it was me who suggested that physical block difference as the cause of the discrepancies. No one else had previously discussed that very relevant point or even attempted to deconstruct my findings on that material difference in the block design compared to the results of the later design.
I also stand by my assertion that once the thermostats (of either flavour) are fully opened, by definition, only additional cooling can be achieved by larger or more rads.
And even after I have learnt from this newest update from Baz, I would advise (and by my actions endorse) fitting a third centre rad if any engine spent most of its time exceeding the fully open temperature of its thermostat.
And although various replies have related to other regimes, and for those I have no argument and now better understand the issues of the thermostat siting (particularly on the later fundamentally poorer cooled blocks), but I don't think this specific suggestion/point has disagreement.
I will try not to give up on you Carruthers until you understand what I said and why.
