I like dyno data for engine performance, but a "cooling SYSTEM" can't be simulated unless you put the dyno in a NASA wind tunnel and replicate the two main stages of flight - takeoff and climb at full throttle (need everything right for that speed) and cruise

 
How do you think dyno's provide cooling?  Why can't they provide two different levels of airflow?   For the record, this inability to test or predict the behavior of anyone's particular plane, is the main reason I say you can't use math to solve this question.  Once you collect the data, math can agree with the results you got, but what good is that? 
 
Cheers,
Rusty (able to predict lotto numbers after they're announced)
