[DeTomaso] Airflow testing

[Matt]

Mike, there is no fan or condensor installed. The test is to see a control scenario to determine the natural flow prior to installing such.
To see the airflow is one thing,and I could determine from initial testing that optimum flow could be achieved by reversing the stock fan and blowing outward.
But then temperature is a factor. Is the air source hotter from the front? Would this negate any airflow gains?
I'll leave that to the engineers, I'm just a data collector...

    My guess is it looks like the positive flow throught out 0-100mph is outward , at least on the upper middle area. The lower section seemed to be less out and a little more in.



  What I find interesting is that even when you're standing still, there's no real indication of inward airflow.  Was the fan running?  Or were you trying to run this test without the fan to see which way the ambient air flowed?

  I think this region is rather turbulent and chaotic, and there probably isn't much formal flow one way or the other unless it's externally influenced by the fan.  Try another test with the fan on.  I'd expect to see the tufts sucked into the grille; the question would be whether they were sucked out as speeds increased?
