I admit that I still believe a 1600, and especially an 1800, is fully
capable of producing 60 hp on takeoff and 30 hp in cruise with a 52 inch
diameter prop--and that the addition of thermal barrier and dispersant
coatings might allow a climb power approaching 40 hp. But none of that
detracts from the basic points--that cars and trucks normally opperate at
surprisingly low ower levels, and that 100 maximum continuous hp from a
Continental O-200 really does mean continuous. Taken in that context, tha
1600 might well be 40 hp maximum and 30 hp cruise; and the thermal coatings
might raise that to 45 hp maximum and 33 hp cruise.

Except for the FACT that it is a rare O-200 that will produce an
honest 100HP under "standard conditions" in stock form, and on an
average day, in average conditions in most of the continental US, 90%
would be doing good on the ground - less in the air.
