In your Franklin manual, under "Operating Limitations", there is a max
manifold pressure/inlet temperature listed.
In the case of the Franklin, it is limited by detonation, not power. The
crank/cylinder heads in the old Franklin are the same as in their (out of
production) turbocharged version ... I can't remember the power figures, but
they were definately more than 220HP, I seem to recall closer to 300
horsepower. The only difference (according to Heinly, now deceased) is the
substitution of low compression pistons.
He said the crank, cylinders and pistons were well up to the task.
I'm not willing to try it though.

I have herd that on very cold days in Alaska with density altitudes below
sea level it is possible to over boost a normally aspirated engine.But not
at 29 inches.
