Hi
Ed;
My theory is that the smaller passages in the Ford cores
will allow more surface to coolant contact, which is what we are looking for.
The size of the Ford cores allow for a far better mounting arrangement, which
positions the cores for optimum airflow. Due to the better position I was able
to build very smooth flowing composite intake ducts, which should
optimize airflow through the cores. Of course none of this matters if I can't
get sufficient coolant flow through them.
I have brought home from work an industrial magnetic tube
flowmeter & a transmitter. I've done a few preliminary tests with the flow
through the cores in series & I've now rewelded the cores in a parallel
configuration, but have not had time to plumb them for a test (had to go to the
in-laws for Christmas). This week I'm concentrating on finishing prepping for
painting and really hope to paint next week. After that I will be away at tech
school for 2 months. I hope to return home every other weekend, at which time I
will complete my flow testing and submit a full report to the list. Preliminary
results look promising. I don't want to post an incomplete report, to avoid any
speculating & theorizing to which I don't have time to respond to right now,
due to my schedule.
Second, Todd is apparently
going to try the Ford evaporator cores as they fit is cowl spacing
requirements better than the GM. However, unless Ford has changed the
construction of their cores, I fear he is going to find that due to the very
small cross section of the Ford core tubes that they will not flow adequate
coolant to keep a 130 hp or more powerful engine within the desired temp
range. However, since I have not tried the Ford cores, it will be
interesting to see whether that hypothesis turns out to be correct or
not
