While testing my 547 type fan out I ran into a major problem the coupler design
I was using was failing at high RPM's.

I now have redesign it to remove the
coupler. The temperature of the heads was well with in the range that I was looking for. Max of 350 degrees on a 100 degree day. Oil never got above
240 degrees.
