Does anybody know how much boost this engine can take expressed in pounds per square inch? Just curious, thanks.

The Max pressure specified in the Operators manual is 51"hg of Manifold Pressure.
That would be 25 psi Absolute measured against a perfect Vacuum.

Depending on how you define "Boost"...
It would be 10 psi above atmospheric pressure at Sea Level.
And 15 psi at 10,000 Ft.
