Subject: Some Taxi testing today. With oil leak.

I got the turbo back from the re-build shop today and did some high speed
taxi testing.  I even got the tail off the ground....  :-)

Cooling has not been an issue yet for easy ground testing.  Coolant and oil
both maxed at 70C (160F).

With Jim Maher's help I fixed my tach and found that I really am getting
more than 4500 RPM. To be specific, 4700 static at 29"MAP and 5300 at 33"
using Jim Mosur's old prop (similar to Tracy's old prop?)  And that's enough
to fly.

First flight was scheduled for Sat the 19th, but the turbo continues to spew
oil-smoke.  I am beginning to wonder if I am feeding it too much oil.  Rusty
says that is an internal restrictor, but looking in the oil inlet it looks
like it goes straight to an oil gallery.  I am feeding it with an AN-6 line.
I think I should try putting in a restrictor but I don't know how big to
make the opening.  Any input?

The oil return is also AN-6 (and bigger) and is all downhill to the pan.
