Mike, thanks for the info!

But I already have the stiffer spring from PZL!

I've been pondering that but I don't think I have enough room in the duct
and I cannot get to the other duct to run one oil line there. Too much
stuff in front of it!

Adding my second cooler made little difference but what difference it made
was definitely in the right direction. I may change it to parallel.

My numbers are 68 and 46 respectively. I think I now know why! (see my post
to Brian)

#3 and 4? Now, THAT is strange. Before I added a baffle in the intake duct
of the plenum my #1 and 2 were the hottest. Now they are within 20C and
none ever hotter than 160C (320F).
