Great! Where can we see these data?

To all  who have expressed interest in stock fan vs electric fan test 
results.  Matt Nall has done a great job of converting the excel file
charts into  jpgs that can be posted to fastvairs and other web sites.
I believe Ken  Hand may put on his and other have offered. I will send
data to those who  have offered. Thanks

There are 6 graphs. There are the main 2 which  show the stock
fan data including CHT, Oil temp, manifold press, duct temp,  and speed.
There is another like above for the electric fan.

4 more  graphs show details better by plotting , for example, CHT in a 
direct  comparison , stock vs electric.

There is a timeline sheet that shows  the time points and when things 
happened for ea of the plots.

There  is a spec sheet for fan used showing the extreme loss of flow when
there is  even a fairly minimal pressure against which the fan must work.

All  data was collected with a datalogger with 12 bit adc and type K  
thermocouples and ea channel was calibrated a 3 point, lower- expected  
temp- and above expected temp using an Omega thermocouple  calibrator.

regards,

frank parker
