(Eds Note:
This implies that the slower the air flow through the radiator (less dynamic
pressure) then the thinner your radiator needs to be for good cooling - but, if
you have the high dynamic pressure, then a more compact thicker radiator
is perhaps a better solution)
When I was
dealing with Howe racing about my radiator, I asked about a 4 row, about 5 inch
thick rad. They said that was the standard for the high speed tracks,
specifically because it allowed them to reduce drag with the thicker
core.
That being
said, my next Howe rad is going to be the same 2 row, 2.5 thick version
that I have now, because I've added the oil cooler on top of it. The
total thickness of rad and oil cooler is about
4.5".
