[V8Vairs] MORE: -- Cooling Pipes

[Sadek, Charles H CIV B-DeptStaff]

Thanks, From all on this. Very helpful to me. Ref increased surface
area. I agree.  I used this solution on my Corvair D Production race car
(#73) where I run the front-mounted oil cooler lines out of both
(Aeroquip at each end of each pipe)and long lengths of 1/2" electrical
conduit with ANC ends brazed on them. I got the idea from Bob Coffin who
used it racing in AZ. It is hard to get the oil up to Temp. I need to
re-think my oil line routing to add the Oil-Stat I have for quicker warm
up.

Toby, thanks for telling us about the weather... ;>(

Oh, changing email to chsadek at adelphia.net at end of month. Current work
emails will no longer apply.

To add to the discussion on radiator pipes, I offer this.  A while back
I asked Bill Bertram, who runs a Chevy V6, how he liked his rear
radiator setup.  

His reply:
"The rear radiator has worked fine for me. It is a 31x19 
mustang aluminum unit from Becool.
The scoop is a 3 piece sheet metal unit that mounts to the tabs I tig
welded 
to the radiator. I have dual Spal fans that are controlled by individual
temp 
propes. 1 is in the intake manifold and the other is in the outlet side
of 
the radiator. The fans are pullers mounted on the rear of the radiator.
I am 
using a Stewart high flow water pump. I do not have AC so no evap. It
never 
gets above 200 degrees. The plumbing is easier than a front mounted
unit. I 
use 1.5 inch stainless tubing."

As far as larger pipes providing more cooling, I think it's on such a
small scale as to be insignificant in this application.  The
cross-sectional area to surface area ratio is a constant pi/2.  With
larger pipes you are moving more water, but slower.  Chuck S was right
in saying you'll get more surface cooling from multiple pipes, but space
becomes the issue.  A good sized radiator and efficient cooling fans
will override any issue with pipes.
