What do you think the of the increased turbulence idea?

IMO, there is no benefit from increased turbulence except packaging.  Any
significant angle will certainly cause separation from the leading edges of
the fins which will increase pressure drop.  I would much rather have the
increased airflow than the turbulence given the same pressure drop.  Look
closely at a good rad and you will see little notches and waves in the fins
to control mixing and turbulence.  These have resulted from much theory and
testing and don't need and turbulence help from you :-)

BTW do you have the K & W book? I can scan a couple of
more pages on this subject and send them to you.

No, but I'd like to.  Do you know where I can get a copy?

I only found the one (I bought) on the internet used book circuit.
