I remember that prop, but don't think it was for a MP increase.. I think it
was to slam more cooling air into the cowling..

Hi Folks!

Was there ever a prop modified with a trailing edge bump for the purpose
of
increasing MP at the ram air inlet?

Faint memory is maybe Lopresti marketed a Hartzerll with a trailing edge
tab.
