Hi,
        Does anyone have a source for A/C evaporators for use as a

radiator?  I

have searched the web and found that everything is keyed to make and model
of the auto it goes in.  That does not help with dimensions and cubic
inches.  If you take one from a salvage yard to determine size then order a
new one from a supplier, seems like there should be an easier way. I know
the salvage yards could probably come up with several but  how does one
test the integrity of a component that has questionable history.  Like mom
use to say "Don't put that in your airplane, you don't know where it's
been".  Thanks for any help.

Why don't you just use a new rad under the engine? Get a free Summit
Racing catalog
and there are a bunch of different sizes of all aluminum rads to choose from.

Admittedly evaporator cores work pretty good as Tracy has been flying
around for
seven years with only one out of the two he has in there actually working
well:-)
(Mazdas are half as hard to cool as we thought :-))

Thanks Paul,
         I thought so after looking at Tracy's site I questioned the total
cubic inches required.  I also asked Charlie Airesman who used a radiator
from Ron Davis about my project and he said to use what Tracy is using.  I
currently have a side view drawing one to one scale and have to shrink the
radiator oil cooler stack a little, the air goes straight through with
expansion and augmenter sections. If I can get the augmentation to work I
can shrink the rad even more if I don't lose my hearing.

That would be great if you can get that exhaust augmented cooling to work.
I would like to see the drawings.

As I said before I would not attempt it in the air. There are way too many
variables for some one less than NASA to develope with unlimited amounts
of our tax money. There are also a bunch of NACA papers on the subject. Do you have
those?  They are not too encouraging.

Klaus flew side by side with Charlie Airesman and Charlie told him on the radio 
he was starting to overheat despite cooling a Soob with only about 100 to 120 HP.
