Probably 9 - 10 but this number depends on various inconsistencies with engine design and build which includes but is not limited to valve design and configuration. Also it's difficult to convert "cubic centimeters" or "cubic inches" into "horse power" due to the fact that one is a measurement of "area" and the other is a measurement of "power". Hope this helps.
