[DeTomaso] Airflow testing

[Tomas Gunnarsson]

The inside air is likely notably warmer than what's behind the car IMO.
Regarding the tufts, for direction of flow you may get a clearer indication
if you hang a sheet of thin plastic (not soft, use something as stiff as
e.g. thick paper) from the top of the mesh. It won't flop around as much and
is easier to "read".

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?
