You might go as far as to build a test bar (sort of like a Spray bar
but oposite) with a required distance from the core, fore and aft.
This might keep everyones measuraments in the same relation to the
Inlet, and core.  Then come up with some test methods.  i.e. 55 mph,
record ambiant temp, take measurements five times and average them,
etc.  Speedometers vary from vehicle to vehicle, and since we are
scatered all over, density might have an affect.

I would think it would be better to make one test "rig" and have us
mount our radiators in a standard fixture that would be easily
attached to the "rig".  We could ship the fixtures to one place and
have all of the testing done on the same rig.  I am not volunteering
for the job, just trying to help eliminate abnormal variation.

Thanks Todd. I had more like 100 MPH in mind :-)
Use the air speed as the reference speed. Use another
manometer in the cab that the driver can read.
