Joel,
We run the cooler on the scavage side, so the pressure is very low. We have
run 100 psi on the cooler with air on diesels and this one was leak checked
at 105 PSI.
They rate them at 300 psi, I just haven't had the guts to take one there.
One of the suppliers I use now also has liquid to air cores, just didn't
have the monster size I needed for the P&W R2000.

Larry,
Are the liquid to air cores the same? as I like the simplicity of the
construction. I guess they have a plate each side of the liquid are i.e
concertinered ( folded) aluminium with surface plate each side. Then
concertinered aluminium to allow air to pass through.
Marvelous idea IM(NT)HO.
How are they assembled i.e brazed or other method?
Does it carry the heat away better than tube types?
Are they lighter?
Who is the manufacturer?
Do they supply direct?
Are they cheaper?
