Hey Mike, I got scared off of
the plate-type coolers as well, just wasn’t confident with the construction
- was able to custom order a Fluidyne cooler through conversations with both
Fluidyne and Summit Racing for my “RX7” – the custom was a
simple change from AN-12 to AN-10. I’m not excited about the
expected weight, but right now outside dimensions and installation location are
more important – I’ll take the 2-3 lb weight penalty in this
application.

Sorry
I'm a little late to the thread here - pc problems.
Anyway
there was a long discussion about these coolers on the RV-list a number of
years ago. They rely on a couple of bent tabs on the end plates to keep the
stack together. Some web surfing found some cases of failures. Scared me off.
The
Setrab coolers look very similar but are better assembled. Lot of RV guys use
them with good results.
The
Fluidyne coolers are no comparison. They are very well built but
heavy. I bought one but in the end didnt use it because I couldnt make it fit
in the space available. I went direct to San Bernadino where they are made to
see if I could get a custom one made to fit. Mistake. I mentioned it was for an
airplane and that was the end of the discussion.

Earl’s quoted specs:
Features

in the U.S.A from aircraft spec aluminum alloy, using the latest vacuum
brazing technology.
- Corrugated
screen internal turbulator plates increase both thermal efficiency and
mechanical strength resulting in the most efficient, smallest and lightest
practical package.
- Manufactured
from thin aluminum plates for the fastest possible heat transfer.
- Inlet
and outlet fittings o-ring to the top plate assembly.
- Designed
for the range of oil flows and air speeds encountered in high performance
automobiles.
- Available
in three widths with inlet and outlet fittings male AN.
- Every
cooler is pressure checked to 175 psi. Periodic samples are burst tested
to 350 psi.
